Initial commit of re2 2014-03-04 library.
Relocated re2.
Initial attempt at porting Makefile.
Added the rest of the libre2 unit tests to automake. Updated the project
to compile libre2 and have libschwa staticly link against it in a nodist
manner.
Made re2 its own autoconf project. Added pthread autoconf detection
instead of hardcoding as per the original makefile.
Split libschwa unit tests into one binary per namespace.
Initial commit of cityhash 1.1.1.
Added SSE and pthread autotools support throughout.
Switch over to using RE2 from C++11 regex since gcc < 4.9 doesn't
properly support them.
