[PATCH 00/12] filter framework and lua integration: complete

[Jason A. Donenfeld]

The beginnings of the filter framework I merged yesterday. This is
the second half. It is a combination of my work and John's, and
allows for a variety of different types of filters to be used with
cgit. We support long lived ones as well as one-off ones, complete
with support for redirecting write(), cleanup functions, init
functions, and more...

This patch set begins with finishing the infrastructure for more
advanced filter types. Then I add lua support, during which time I
make a few changes to the infrastructure. I should have split this out
into a separate commit, but I didn't. It should be fairly straight-
forward though. Finally, this series ends with adding support for the
email-filter option and writing both an old style "exec:" script for
adding gravatars, as well as a new style "lua:" script for the same
thing.

We managed to do all of this in under 500 lines of additions, evidently.
