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
It turned out a lot of the namespace stuff still worked. The biggest thing for the first pass is that we don't fallback to the global function or constant if there isn't a namespaced one.
Also, when a constant has a ##\## anywhere in it it throw an error when it isn't defined, instead of assuming the string.
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
