Update to 38.0.2125.58
Fix patching
ui_unittests are really gone.
Disable browser_tests and unit_tests for now, they require unavailable mock4js
Fix when TESTS are on, this file does not make sense on FreeBSD.
Disable GPU information collection on BSD, it uses Linuxy interfaces.
This should work, but it doesn't without the big hammer.
Back to internal libvpx because Chromium uses unreleased features of it.
Ensure all relevant third-party code is saved.
Fix build with external protobuf.
Fix build on FreeBSD.
Disable some GPU code on FreeBSD for now :(
Revert "Disable browser_tests and unit_tests for now, they require unavailable mock4js"

This reverts commit 0d9fef72ec07cd60a9c7c52fe61c5346d1cc3119.

mock4js is now excluded from deletion in Makefile.
Do not prune mock4js, it is used by some unittests and not available
elsewhere in the Ports Tree.
