Update the build infrastructure to use Git instead of Subversion

Summary:
The doc repository is not mirrored to Subversion so updating the
repository from Subversion does not make sense. Remove
Subversion-specific files too.

While here remove now defunct $FreeBSD$ markers in affected files.

Test Plan:
make clean
make update
make
