The code for obtaining a BuildReader for evaluating moz.build files
is generic and non-trivial. We already had a custom implementation
for `mach file-info` that implemented support for Mercurial
integration. Bug 1383880 will introduce a second consumer.
So this commit factors out the "obtain a BuildReader" logic into
a reusable function on our base MozbuildObject class. This makes
it easily available to various parts of the build system and mach
commands.
As part of the change, we detect when ``.`` is being used as the
revision and verify the working directory is clean. This behavior
can be disabled via argument if unwanted. But it's useful by default
to ensure consumers aren't expecting to read uncommitted changes.
