Markus Metzger b0627500e8 btrace: maintenance commands

Add maintenance commands that help debugging the btrace record target.
The following new commands are added:

maint info btrace
  Print information about branch tracing internals.

maint btrace packet-history
  Print the raw branch tracing data.

maint btrace clear-packet-history
  Discard the stored raw branch tracing data.

maint btrace clear
  Discard all branch tracing data.  It will be fetched and processed
  anew by the next "record" command.

maint set|show btrace pt skip-pad
  Set and show whether PAD packets are skipped when computing the
  packet history.
