Thrift: No using namespace.

Summary:
using namespace XXX; is tricky because it imports a lot of crap into your namespace.
Also, if we ever decide to remove boost as a dependency, "using namespace boost"
makes it harder.

This patch removes all using namesapce XXX; with one or more using XXX::YYY;
There are some exceptions, such as test, tutorial, namespace std, and
facebook namespaces.

Test Plan:
Recompiled thrift.
grep --binary-files=without-match -r 'using namespace' . | \
  egrep -v '^[^:]*: *using namespace (std;$|facebook)' | \
  grep -v '<< endl' | \
  grep -v '[^:]*/tutorial/' | \
  grep -v '^./test/'

Revert Plan: ok

Notes: I wouldn't bother, but it is fixathon.
