Add FilePath to base namespace.

Add FilePath to base namespace.

This updates headers that forward-declare it and a few random places to use the namespace explicitly. There us a using declaration in file_path.h that makes the rest compile, which we can do in future passes.

There were no problems landing this! I closed the tree but only had to clobber
one bot with bad dependencies. I also verified there were no >80 col lines.

Good job! This was also probably a good time to land.  Release eng will cut
a new version a week from monday, so there will be some folks begging to
backport a few things after that date.... and it will be good that you
won't change stuff around that point (so that patches will merge cleanly).
