Change fileapi namespace to content for files that are moved under content/

Change fileapi namespace to content for test files that are moved under content/

Note that this temporarily adds some content:: notion in webkit/ (mostly for friend'ing / forward decls)

This also includes some refactoring in some test code (namely obfuscated_file_util_unittest.cc) to work around
cross-namespace friend'ing.

net/ LGTM.  TBRing me on this was completely reasonable, just thought I'd chime
in.
