libdebugger: Fixes to debugging, ARM support, locking, and gcc-7.1 warnings.

- Add `printk` support to aid multi-core debugging.
- Add lock trace to aid lock debugging.
- Fixes to gcc-7.1 warnings.
- Fixes from ticket #2879.
- Add verbose command controls.
- Change using the RTEMS sys/lock.h API to manage exception threads.
- ARM hardware breakpoint fixes. Support for SMP stepping
  is not implemented, this requires use of the context id
  register.

Closes #2879.
