Add the gdb remote target operations for branch tracing.
We define the following packets:
Qbtrace:bts enable branch tracing for the current thread
returns "OK" or "Enn"
Qbtrace:off disable branch tracing for the current thread
returns "OK" or "Enn"
qXfer:btrace:read read the full branch trace data for the current thread
