Dragonite, which have only one working watchpoint unit.

ARM11: fix breakpoints with GDB
This fixes a bug whereby GDB's breakpoints weren't activated.
The root cause is a confused interface to resume(). Fix by
almost ignoring the "handle breakpoints" parameter; it only
seems related to the case of skipping breakpoint-at-PC.
Update a few coments to clarify what's happening.

Cortex-M3 vector_catch testing support
The "cm3-ftest.cfg" can be used to verify that OpenOCD handles
certain faults correctly:
- Test #1: it ignores faults that it wasn't told to catch
- Test #2: if vector_catch is told to catch, it catches
The "fault.c" generates ASM code to trigger faults, while the
config script loads and runs pre-compiled code.
