James E. Blair 3d5f87359d Add configuration support for negative regex
The re2 library does not support negative lookahead expressions.
Expressions such as "(?!stable/)", "(?!master)", and "(?!refs/)" are
very useful branch specifiers with likely many instances in the wild.
We need to provide a migration path for these.

This updates the configuration options which currently accepts Python
regular expressions to additionally accept a nested dictionary which
allows specifying that the regex should be negated.  In the future,
other options (global, multiline, etc) could be added.

A very few options are currently already compiled with re2.  These are
left alone for now, but once the transition to re2 is complete, they
can be upgraded to use this syntax as well.
