[PATCH v2 0/1] Write trace2 output to directories

[Josh Steadmon <steadmon@google.com>]

Persistently enabling trace2 output is difficult because it requires
specifying a full filename. This series teaches tr2_dst_get_trace_fd()
to create files underneath a given directory provided as the target of
the GIT_TR2_* envvars.

Changes since V1:

* No longer supports timestamp templates.
* No longer supports filename prefixes.
* Always creates filenames based on the final component of the trace2
  SID.
