protobuf: bump to version 3.0.0

It also changes the python-protobuf.hash file to be a symbolic link to
../protobuf/protobuf.hash so that both hash files don't have to be
updated when protobuf is bumped.

In addition, the 0001-disable-unneeded-build-dependencies.patch patch
from package/python-protobuf/ is removed because it has been merged
upstream.

-It's not possible to define "#error" inside a define.
-It causes 'error: stray ‘#’ in program' compilation error.
-
-Now the define GOOGLE_PROTOBUF_ATOMICOPS_ERROR is the error message
-and it's used along the code together "#error".
