Summary: Update the C files under edenscm/mercurial/cext to use absolute includes from the repository root. Also update a few of the libraries in edenscm/mercurial that the cext code depends on. This makes these files easier to build with Buck in fbsource, and reduces the number of places where we have to use deprecated Buck functionality to help find these headers. This also allows autodeps to work with the build targets for these rules. Reviewed By: xavierd Differential Revision: D19958221 fbshipit-source-id: e6e471583a795ba5773bae5f16ed582c9c5fd57e
