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
a number of regressions in older versions of GDB regarding remote thread
display. Trust me, it's great.

This patch removes the display_str member in the thread_detail struct.
This member was not being used and provides no additional benefit over
the thread_name_str and extra_info_str members. This change is made in
preparation of support for the qXfer:threads:read packet, which will
modernize how thread information is shared with GDB.

Some targets (Cortex M) require more complicated calculations for
turning the stored stack pointer back into a process stack pointer.
For example, the Cortex M stores a bit in the auto-stacked xPSR
indicating that alignment had to be performed and an additional 4
byte padding is present before the exception stacking. This change
only sets up the framework for Cortex-M unstacking and does not
add Cortex-M support.
Note: this also fixes the alignment calculation nearly addressed by
change #2301 entitled rtos/rtos.c: fix stack alignment calculation.
Updated calculation is in rtos_generic_stack_align.

Each RTOS implementation uses it's own (similar) code to free
the thread list. There are some additional issues:
<--->
if (pointer != NULL)
free(pointer);
<--->
This is not necessary, free(NULL) is perfectly ok.
<--->
free(rtos->thread_details);
rtos->thread_details = NULL;
rtos->thread_count = 0;
<--->
The 3rd line has been missing for all RTOS but ChibiOs. There are paths
in the code where rtos->thread_count is never set to NULL, which can
lead to null pointer dereference of rtos->thread_details.

Rename cortex_m3 target to use a more correct cortex_m name.
This also adds a deprecated_name var so that older scripts issue a warning
to update the target name.
cfg files have also been updated to the new target name.
