- 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.
