*** TEST RESULTS FOR COMMIT d33501a51f46193387ff2d101752a9a878202f82 ***

Author: Markus Metzger <markus.t.metzger@intel.com>
Branch: master
Commit: d33501a51f46193387ff2d101752a9a878202f82

record-btrace: add bts buffer size configuration option
Allow the size of the branch trace ring buffer to be defined by the
user.  The specified buffer size will be used when BTS tracing is
enabled for new threads.

The obtained buffer size may differ from the requested size.  The
actual buffer size for the current thread is shown in the "info record"
command.

Bigger buffers mean longer traces, but also longer processing time.
