From: Derrick Stolee <dsto...@microsoft.com>
Documentation/technical/api-trace2.txt contains the full details
of the trace2 API and the GIT_TR2* environment variables. However,
most environment variables are included in Documentation/git.txt,
including the GIT_TRACE* variables.
Add a brief description of the GIT_TR2* variables with links to
the full technical details. The biggest difference from the
original variables is that we can specify a Unix Domain Socket.
Mention this difference, but leave the details to the technical
documents.
