This patch adds support for p packet responses by targets configured
with RTOS support. This change required moving to a rtos_reg struct,
which is similar to struct reg used by targets, which resulted in
needing to update each stacking with register numbers. This patch also
allows targets with non-linear register numbers to function with RTOSes
as well.

Virtual targets, like mem_ap, do not or cannot implement the required
functionality to accept a GDB connection. In the case of mem_ap, the
method get_gdb_reg_list() is missing and a following connection from
gdb causes OpenOCD to segfault.
OpenOCD opens a GDB port for each target; it's always possible to
connect, by mistake, GDB to one virtual target.
Add a method to check if the target supports GDB connections (for the
moment just checking if get_gdb_reg_list is implemented).
Skip opening a gdb server for every targets that don't support GDB
connections.

The argument passed to global config command "gdb_port" is usually,
but not always, a TCP port number. In case of multiple targets, this
numeric value is used as the first port of a set of consecutive TCP
ports assigned one per target.
If the argument is not a numeric value (e.g. "pipe", "disabled", ...)
then incrementing it for the next target has no sense.
Add the option "-gdb-port number" to the commands "target create" and
"$target_name configure" to override, for the specific target, the
general global configuration.
This permits to use a per target "-gdb-port disabled", when no gdb
port is required for that specific target.
It also makes possible to choose a custom TCP port number for each
target, overriding the usual sequence of consecutive port numbers.

Every TCL command can be renamed (or deleted) and then replaced by
a TCL proc that has the same name of the original TCL command.
This can be used either to completely replace an existing command
or to wrap the original command to extend its functionality.
This applies also to the OpenOCD command "shutdown" and can be
useful, for example, to set back some default value to the target
before quitting OpenOCD.
E.g. (TCL code):
rename shutdown original_shutdown
proc shutdown {} {
puts "This is my implementation of shutdown"
# my own stuff before exit OpenOCD
original_shutdown
}
Unfortunately, sending a signal (or pressing CTRL-C) to terminate
OpenOCD doesn't trigger calling the original "shutdown" command
nor its (eventual) replacement.
Detect if the main loop is terminated by an external signal and
in such case execute explicitly the command "shutdown".
Replace with enum the magic numbers assumed by "shutdown_openocd".
Please notice that it's possible to write a custom "shutdown" TCL
proc that does not call the original "shutdown" command. This is
useful, for example, to prevent the user to quit OpenOCD by typing
"shutdown" in the telnet session.
Such case will not prevent OpenOCD to terminate when receiving a
signal; OpenOCD will quit after executing the custom "shutdown"
command.

Commit 5087a955 added custom signal handlers for the openocd
server process.
Before this commit, when openocd is run as a background process
having the same controlling terminal as gdb, Control-C would be
handled by gdb to stop target execution and return to the gdb prompt.
However, after commit 5087a955, the SIGINT caused by pressing
Control-C also terminates openocd, effectively crashing the
debugging session. The only way to avoid this is run openocd in
a different controling terminal or to detach openocd from its
controlling terminal,
thus losing all job control for the openocd process.
This patch improves the server's handling of POSIX signals:
1) Keyboard generated signals (INT and QUIT) are ignored
when server process has is no controlling terminal.
2) SIGHUP and SIGPIPE are handled to ensure that .quit functions
for each interface are called if user's logs out of X
session or there is a network failure.
SIG_INT & SIG_QUIT still stop openocd
when it is running in the foreground.

In a multi-target environment we are supposed to have a single
gdb server for each target (or for each group of targets within
a SMP node).
By default, the gdb attached to a server sends its command to
the target (or to the SMP node targets) linked to that server.
This is working fine for the normal gdb commands, but it is
broken for the native OpenOCD commands executed through gdb
"monitor" command. In the latter case, gdb "monitor" commands
will be executed on the current target of OpenOCD configuration
script (that is either the last target created or the target
specified in a "targets" command).
Fixed in gdb_new_connection() by replacing the current target

This change contains an alternative to Matthias Welwarsky's #4130
(target-prefixed commands) and to #4293 (event handlers).
get_current_target() must retrieve the target associated to the current
command. If no target associated, the current target of the command
context is used as a fallback.
Many Tcl event handlers work with the current target as if it were
the target issuing the event.
current_target in command_context is a number and has to be converted
to a pointer in every get_current_target() call.
The solution:
- Replace current_target in command_context by a target pointer
- Add another target pointer current_target_override
- get_current_target() returns current_target_override if set, otherwise
current_target
- Save, set and restore current_target_override to the current prefix
in run_command()
- Save, set and restore current_target_override to the event invoking
target in target_handle_event()
While on it use calloc when allocating a new command_context.

This patch adds support for the qXfer:threads:read packet. In addition
to providing a more efficient method of updating thread state, recent
versions of GDB (7.11.1 and up) can also report remote thread names.
While thread names are not enabled in this patch due to its limited
applicability at the moment, it can be enabled at a later date with
little effort.
As a part of revamping how threads are presented to GDB, extra info
strings for each of the supported RTOSes were updated to match
conventions present in the GDB source code. For more information, see
remote_threads_extra_info() in remote.c. This results in a much smoother
experience when interacting with GDB.
It is also worth mentioning that use of qXfer:threads:read works around

To speed up downloads, OpenOCD sends gdb OK when a write is received,
even before the write has actually occurred. The failure is then
returned for the next write. That leads to the following confusing
behavior:
```
(gdb) p/x *((int*)0xdeadbeef)=8675309
$2 = 0x845fed
(gdb) p/x *((int*)0x80000000)=6874742
Cannot access memory at address 0x80000000
```
While it's actually the first write that failed.
This change hacks around this problem by not sending OK for small writes
(len<8) until the write has actually occurred. This does not impact
download speed, since during downloads (almost) all writes will have
much larger length.

The current implementation is not suitable for user provided data
because it does not detect invalid inputs in many cases. For example,
the string "aa0xbb" is successfully converted to the 3 bytes: 0xaa,
0x00 and 0xbb. An other example is "aabi" which is successfully
converted to the 2 bytes: 0xaa and 0x0b. Both are obviously incorrect.
Make unhexify() robust on invalid data and use more appropriate data
types for its parameters. Also, add a small documentation for the
function.

Currently, the maximum size of a command sent to the TCL server is
4k. This patch increases this limit up to 4M.
Reasoning:
To get high-speed JTAG data transfers, I'm using a very long shift
register. This reduces the overhead of the state changes, as well as the
latency due to the common USB adapter transfers considerably. In order
to submit those long DRSCAN commands to OpenOCD over the TCL/TCL
interface, long TCL command lines are required. This is enabled by this
patch.
v3:
Address review comments. Drop line instead of connection when realloc()
fails.
Changes in v2 of this patch:
The line buffer is allocated dynamically to avoid an OpenOCD memory
overhead if the large buffers are not used. The buffer starts at 4K and
increases exponentially up to 1M, and then linearly in 1M increments up
to 4M.

This patch might influence openocd Tcl commands behaviour in subtle
ways, please give it a nice testing.
The idea is that if an OpenOCD Tcl command returns an error, an
exception is raised, and then the return code is propogated all the
way up (or to the "catch" if present). This allows to detect
"shutdown" which is not actually an error but has to raise an
exception to stop execution of the commands that follow it in the
script.
openocd_thread special-cases shutdown because it should then terminate
OpenOCD with a success error code, unless shutdown was called with an
optional "error" argument which means terminate with a non-zero exit
code.

Comment in gdb_server code mistakenly attributed constant warnings
about unexpected acknowledgement to the ACK packet sent by GDB when
establishing connection. However that is not the case, OpenOCD
gdb_server is handling this packet correctly without an warnings. This
warning instead was caused by the ACK packet which GDB sends right after
going into noack mode. Because OpenOCD gdb_server is already in noack
mode at this state, it emits warning about it. This is a documented GDB
behaviour
(https://sourceware.org/gdb/onlinedocs/gdb/Packet-Acknowledgment.html)
so there is no reason to scare users with warnings in this case.
This patch basically introduces two-level noack mode: after receiving
QStartNoAckMode gdb_server will set noack_mode to 1, then it will
receive this last ACK packet, but instead of printing a warning,
noack_mode will be increased to 2. Should there be any other ACK packets
after that, they will be properly reported by warning. All other code
that relies on noack_mode checks it for "!= 0", so there will be no
difference if it is 1 or 2.

The File I/O remote protocol extension allows the target to use the
host's file system and console I/O to perform various system calls.
To use the function, targets need to prepare two callback functions:
* get_gdb_finish_info: to get file I/O parameters from target
* gdb_fileio_end: pass file I/O response to target
As target is halted, gdb_server will try to get file-I/O information
from target through target_get_gdb_fileio_info(). If the callback function
returns ERROR_OK, gdb_server will initiate a file-I/O request to gdb.
After gdb finishes system call, gdb will pass response of the system call
to target through target_gdb_fileio_end() and continue to run(continue or step).
To implement the function, I add a new data structure in struct target,
called struct gdb_fileio_info, to record file I/O name and parameters.

The format of 'M' packet is 'M addr,length:XX...'. The data
follows ':' immediately. No need to '+2' to SEPARATOR in
unhexify(), because SEPARATOR points to data correctly.

The calculation for reg_packet_size in gdb_get_registers_packet() could
generate a wrong result in the case of multiple registers whose size is
not a multiple of 8.
The current calculation sums the sizes for all registers then rounds the result
up to the next multiple of 8.
Instead it should round each register size up individually and sum the results for all registers.

- works on Cortex-M3 with ThreadX and FreeRTOS
Compared to original patch a few nits were fixed:
- remove stricmp usage
- unsigned compare fix
- printf formatting fixes
- fixed a bug with overrunning a memory buffer allocated with malloc.
Fix a bunch of typos.
Most are in code comments, so nothing should break. UNKOWN_COMMAND and
CMD_UNKOWN are not used elsewhere, so correcting the spelling should
also not break anything.
the error values is not part of the interface to the user,
so they should never be printed in LOG_INFO or LOG_USER.
Printing them in LOG_DEBUG() rarely makes much sense but
is OK.

gdb connect can fail when the flash has not been probed.
During gdb connect, the flash layout is reported, but this
can not be automatically detected for a target that is
powered up and OpenOCD supports connecting to gdb server
even if the target is powered down.
The solution is to turn of the gdb_memory_map feature.
