Remember, don't cast your pointers between types of different sizes!
While the FreeRTOS handlers attempt to account for different pointer and
list widths, the types used are always fixed, so this will _remain_
broken if/when someone targets FreeRTOS on 8/16/64 bit targets. (Note
that this patch does not _change_ that, it was fixed to 32bit before as
well)
In the meantime, this properly handles 32bit reads on a mips BE system
(ath79) as well as remaining fully functional on x86_64.

The function free() can be called with a NULL pointer as argument,
no need to check the argument before. If the pointer is NULL, no
operation is performed by free().
Remove the occurrences of pattern:
if (ptr)
free(ptr);
While there replace a sequence malloc(size)+memset(,0,size) with a
calloc(1,size).
Replace a pointer assignment to '0' with an assignment to NULL.
In server/*, an error is logged if the ptr was already NULL. This
cannot happen since the pointer was already referenced few lines
before and openocd would have been already SIGSEGV in that case,
so remove the log.

The script checkpatch available in new Linux kernel offers an
experimental feature for automatically fix the code in place.
While still experimental, the feature works quite well for simple
fixes, like spacing.
This patch has been created automatically with the script under
review for inclusion in OpenOCD, using the command
find src/ -type f -exec ./tools/scripts/checkpatch.pl \
-q --types POINTER_LOCATION --fix-inplace -f {} \;
then manually reviewed.
OpenOCD coding style does not mention the space around pointer's
asterisk, so no check is enforced. This patch only makes the style
uniform across the files.
The patch only changes amount and position of whitespace, thus
the following commands show empty diff

1. Add get_thread_reg() to rtos. It's used in rtos_get_gdb_reg() to read
the value of a single register, instead of reading all register values
by calling get_thread_reg_list().
2. Add set_reg() to rtos. gdb_server uses this to change a single
register value for a specific thread.
3. Add target_get_gdb_reg_list_noread() so it's possible for gdb to get
a list of registers without attempting to read their contents.
The clang static checker doesn't find any new problems with this change.

Currently size of the GDB buffer is 16384 bytes but it is treated as
nul-terminated string in most of the code, so effective size of the
buffer is actually 16383 bytes. OpenOCD responds with `PacketSize=3fff`
to qSupported request. Result of GDB's `m` command is encoded in hex so
each data byte uses two bytes in the buffer. As a result GDB will split
bulk read requests into chunks 0x1fff bytes each. This causes troubles
on targets (or memory regions) which support only aligned, word-sized
access (such as MMIO buffers).
Steps to reproduce (psoc6 target):
gdb> dump binary memory dump.bin 0x040320000 (0x040320000 + 65536)
OpenOCD:
Error: Failed to read memory at 0x40321ffe
Error: Failed to read memory at 0x40321000
Error: Failed to read memory at 0x40323000
Error: Failed to read memory at 0x40325ffe
Error: Failed to read memory at 0x40329ffa
Error: Failed to read memory at 0x40329ffc
Error: Failed to read memory at 0x4032bffc
Error: Failed to read memory at 0x4032dffa
Consolidate GDB_BUFFER_SIZE usage: ensure size of each buffer is
(GDB_BUFFER_SIZE + 1), add explicit comment that additional byte is used
for nul-termination. Report correct size of the buffer to GDB (0x4000)
as recommended in GDB's docummentation: `if the stub stores packets in a
NUL-terminated format, it should allow an extra byte in its buffer for
the NUL`
Checked with clang-asan, clang-analyzer, valgrind - no new errors.
