[PATCH v4 04/14] trace2:data: add trace2 regions to wt-status

[Jeff Hostetler via GitGitGadget]

From: Jeff Hostetler <jeffh...@microsoft.com>

Add trace2_region_enter() and trace2_region_leave() calls around the
various phases of a status scan.  This gives elapsed time for each
phase in the GIT_TR2_PERF and GIT_TR2_EVENT trace target.

Also, these Trace2 calls now use s->repo rather than the_repository.
