a28dea0fe4 target/cortex_m: avoid dwt comparator overflow
Avoid ever overflowing the DWT_COMPARATOR array by allocating space for
16 comparators (the field is masked by 0xf).

On a stm32f767zi chip (on a nucleo-767zi board) I've been seeing crashes
with address sanitizer enabled due to its (apparent) 10 present
comparators. This appears to be due to
https://sourceforge.net/p/openocd/tickets/178/.

In non-address sanitizer builds, this would likely cause some random
memory to be written to in some cases. (see above bug for observations).

2231da8ec4 target: restructure dap support
- add 'dap create' command to create dap instances
- move all dap subcmmand into the dap instance commands
- keep 'dap info' for convenience
- change all armv7 and armv8 targets to take a dap
  instance instead of a jtag chain position
- restructure tap/dap/target relations, jtag tap no
  longer references the dap, daps are now independently
  created and initialized.
- clean up swd connect
- re-initialize DAP also on JTAG errors (e.g. after reset,
  power cycle)
- update documentation
- update target files

related to a configured target.

828ee07657 server: bind to IPv4 localhost by default
Since OpenOCD basically allows to perform arbitrary actions on behalf of
the running user, it makes sense to restrict the exposure by default.

If you need network connectivity and your environment is safe enough,
use "bindto 0.0.0.0" to switch to the old behaviour.

935f0c5cc2 gdb_server: fake step if thread is not current rtos thread
gdb assumes that a rtos can make any thread active at will in response
to a 'Hg' packet. It further assumes that it needs to step-over after
setting a breakpoint on frame #0 of any non-current thread. Both
assumptions are not valid for an actual rtos. We fake the step-over to
not trigger an internal error in gdb. See
https://sourceware.org/bugzilla/show_bug.cgi?id=22925 for details.

cbf7889873 gdb_server: fix ignored interrupt request from gdb during stepping
Normally, when a ctrl-c is received from gdb, a SIGINT is reported back
unconditionally to tell gdb that the target has stopped in response.
However when a rtos support was configured, the rtos awareness overwrote
the signal with an actual thread state, which gdb then ignored and got
stuck without the user able to interrupt.
