Marker for start of git trunk commits.

This is here for the benefit of 'git describe'.
Update libgit2 version from 0.20.0 to 0.21.1

It seems that couple of our patches are now upstream.

Also, set EXECUTABLES= in the build.sh file so the test
binary gets validated and translated.

Also, fix compiler warnings (mostly adding ll to
integer constants).
