Bug 1328184 - Part 1: Deal better with an existing source checkout; r=mystor

Browse Source 
Since individual config files have different source repos declared,
it's better to deal with each individual source directory separately.
Also make sure to revert any of the existing changes in each directory
so that attempts to apply patches to the source directory or import
our static analysis checks into clang-tidy are guaranteed to always
succeed.
