87c90393fe Cleanup of config/includes.
Remove a use of AH_BOTTOM from configure.ac. This macro is used by
autoheader to add '#include' of some include file to the end of
config.h.in and then to config.h. OpenOCD can be built with a custom
config.h, so it's preferable to move these '#include' statement directly
in the C files that need them dropping this unneeded dependency.

It also causes problems when I want to use the gnulib library (which
comes with its own Makefile, and does not have the same include path as
the top-level Makefile).

So this change touches a lot of files, but is actually really simple. It
does not affect functionality at all.

a5471b1b2c drivers/cmsis-dap: add multidrop capability
Uses CMSIS-DAP v 1.2 or higher protocol command DAP_SWD_Sequence
to write to DP TARGETSEL register. This write is not acknowledged
by device so we cannot use standard DAP_Transfer

ff755a575e drivers/cmsis-dap: flush read
Some CMSIS-DAP adapters keep buffered packets over
USB close/open so we need to flush up to 64 old packets
to be sure all buffers are empty.

Flush just after cmsis_dap_open() and in the case of command mismatch.

80970811f4 drivers/cmsis-dap: improve error checking
Check returned HID report number (or the first byte of returned
bulk packet) which should be equal to the issued command or 0xff
in case of the command is not implemented.

Fix error return paths in cmsis_dap_init() to clean up the adapter
connection.

Don't fail cmsis_dap_init() when an unimportant function fails
(for the case the adapter doesn't implement some parts of protocol).

01030fb893 drivers/cmsis-dap: tidy up buffer access
Each one of CMSIS-DAP command handlers was responsible for setting
HID report number, which in case of USB bulk transport was not used
at all. The command had to be filled with 1 byte offset whereas
the response was read without an offset.

Introduce 'command' and 'response' pointers into struct cmsis_dap.
Use them for filling the command and read the response respectively.
CMSIS-DAP command parameter are now at positions as documented in
https://arm-software.github.io/CMSIS_5/DAP/html/group__DAP__Commands__gr.html
Adjust buffer allocation for HID and USB bulk transports.

While on it, use h_u32_to_le() and h_u16_to_le() instead of per-byte
writes.

fed42ccfd3 cmsis-dap: don't update the packet size across backends.
The hidapi cmsis-dap backend is using a packet_size of
64+1: 64 is the bMaxPacketSize0 and 1 is the hid Report-Id.

In hidapi::hid_write(), the packet_size is decremented by 1 and
stored for the next transfer.
The packet_size is now valid bMaxPacketSize0=64,
so when hid_read() is called, libusb_bulk_transfer() finishes w/o timeout.

For the libusb bulk backend, the same packet_size of 64+1 is used,
but there's no hid_write() to decrement and store it for the next read.

So the next time a read is done, it will try to read 64+1 bytes.

Fix this by putting the packet logic within each backend.
Use calloc() to allocate the struct cmsis_dap to be on safer side.

8f927d5164 Add CMSIS-DAP v2 support
This change implements CMSIS-DAP v2 which works with raw USB bulk transfers.

The old driver is now split into a generic CMSIS part and a HID backend,
with a new raw USB backend for CMSIS-DAP v2.

New commands:
- cmsis_dap_backend (usb_bulk | hid | auto)
- cmsis_dap_usb interface <interface number>
