Teach git to load default Trace2 settings from the system config (usually
"/etc/gitconfig"). The existing GIT_TR2_* environment variables can be used
to override the new system defaults. It also includes a little startup
refactoring.

Note: I found interactive testing of this feature to be awkward on some
platforms because of the use of prefix- or runtime-prefix-relative locations
for the system configuration. It was easy to accidentally use an officially
installed version of git to set a system config variable in the official
system config directory; and then when testing with the test version of git,
that value would not be seen because it was looking for the system config
file in a different directory.

Jeff Hostetler (4):
  trace2: refactor setting process starting time
  trace2: add absolute elapsed time to start event
  trace2: find exec-dir before trace2 initialization
  trace2: use system config for default trace2 settings
