Fixing rat warnings

We need to clean up the RAT report to 0. Apache projects aren't supposed to
release until they have shown that all of their files have proper headers.

Note that although most of the files are just missing headers, some of them
explicitly say copyright by facebook and released under the Thrift (not Apache)
license. I'll generate a list of them, but I'd really appreciate it if someone
from facebook could in verify that they intend to license them to Apache.
