Initial support for disassembling Thumb2 code. This works only for
Cortex-M3 cores so far. Eventually other cores will also need Thumb2
support ... but they don't yet support any kind of disassembly.
- Update the 16-bit Thumb decoder:
* Understand CPS, REV*, SETEND, {U,S}XT{B,H} opcodes added
by ARMv6. (It already seems to treat CPY as MOV.)
* Understand CB, CBNZ, WFI, IT, and other opcodes added by
in Thumb2.
- A new Thumb2 instruction decode routine is provided.
* This has a different signature: pass the target, not the
instruction, so it can fetch a second halfword when needed.
The instruction size is likewise returned to the caller.
* 32-bit instructions are recognized but not yet decoded.
- Start using the current "UAL" syntax in some cases. "SWI" is
renamed as "SVC"; "LDMIA" as "LDM"; "STMIA" as "STM".
- Define a new "cortex_m3 disassemble addr count" command to give
access to this disassembly.
Sanity checked against "objdump -d" output; a bunch of the new
instructions checked out fine.

converts a number of 'simple string lookup tables' into NVP tables.
These NVP tables will be used by various commands coming in the next patch.

into the target implementation.
Also target_process_reset() is now simpler and has error handling,
e.g. if assert reset fails, then target_process_reset() will propagate
that error.
cmd_ctx was passed in to examine(), which is wrong - removed that.

from pre/post_reset event scripts. Adding the second parameter was
a mistake seen in retrospect. this gives precise control in post_reset
for *when* the post reset speed is set. The pre_reset event was
added *after* the second parameter to jtag_khz/speed
- the target implementations no longer gets involved in the reset mode
scheme. Either they reset a target into a halted mode or not.
target_process_reset()
detects if the reset halt failed or not.
- tcl target event names are now target_N_name. Mainly internal
at this early stage, but best to get the naming right now.
- added hardcoded reset modes from gdb_server.c. I don't know precisely what
these defaults should be or if it should be made configurable. Perhaps some
hardcoded defaults will do for now and it can be made configurable later.
- bugfix in cortex_m3.c for reset_run_and_xxx?
- issue syntax error upon obsolete argument in target command instead of
printing message that will surely drown in the log
