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.

  • Property mode set to 100644
