I was learning from @jdelong and he said that you should use
double quotes for local includes and angle brackets for library
includes. I asked why our code was the way it was, and he said he wanted
to clean it up. I beat him to it :)
Conflicts:
hphp/runtime/base/server/admin_request_handler.cpp
hphp/runtime/vm/named_entity.h
Also, since its always present, remove the special case
code for adding systemlib to a RepoAuthoritative repo,
and clean up all the magic variables for finding systemlib.
If HHVM_SYSTEMLIB is set, and the file exists, it will be
used as systemlib, otherwise, the embedded one will be used.
