e0fc21a2a7 adiv5_swdp: allow to connect to a sleeping target by pulling SRST 
This patch introduces a new command, "connect_srst [enable|disable]"
which allows to enable special mode in which SRST would be pulled low
before the SWD scan till attaching to a target.

Since on Cortex-Mx the SRST signal doesn't gate JTAG and SWD, it's
possible to connect to a target while holding reset, ask it to stop at
reset vector and only then deassert reset, thus allowing to attach to
the kind of firmware that goes immediately to sleep or disables
debugging by other means early on start.

Tested on an STM32VLDiscovery board with STM32F100 configured to go to
STOP mode and executing WFI in the very beginning of main().

ffda30f393 Add support for a more comprehensive target description, including the additional v7m registers. 
This doesn't work with vanilla gdb, as for reasons unknown said vanilla gdb doesn't support XML target descriptions queried from the remote.

Add code to the fault unwinder to deal with the stack alignment fixup and FP registers.  Avoid saving/restoring registers that don't get trashed.
