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.
