chromium: Update all channels to latest versions.

Browse source 
With this commit, the following new upstream versions are introduced:

stable: 35.0.1916.153 -> 36.0.1985.125
beta:   36.0.1985.84  -> 37.0.2062.44
dev:    37.0.2054.3   -> 38.0.2101.0

All builds were successfully tested on my machine, however in order to
update the beta and dev channels, a few additional modifications were
necessary:

 * Don't update address_input_strings.grdp anymore because this has been
   done/fixed upstream and was relevant in version 37.0.2054.3 _only_.
 * No need to fix references to /usr/bin/gcc in version 38 anymore.
 * Constrain patch for Angle (introduced in 4cbedd7) to version 37 only,
   because it already has been applied upstream in version 38.
 * Drop user namespaces patch for version 31 up until version 35,
   because version 36 is already in stable.
 * Don't try to build bundled Clang and/or even build using Clang.
 * Remove obsolete patchPhase commands that are specific to version 35
   and older.

While testing the dev version 38 I came accross a font rendering issue
which needs to be addressed ASAP (perhaps related to #3187), however the
browser works otherwise.

commit ff4e8b4af04c58fc4c58ee7ed108aefcdc26a960
Author: aszlig <aszlig@redmoonstudios.org>
Date: Thu May 16 14:17:56 2013 +0200
zygote: Add support for user namespaces on Linux.
The implementation is done by patching the Zygote host to execute the sandbox
binary with CLONE_NEWUSER and setting the uid and gid mapping so that the child
process is using uid 0 and gid 0 which map to the current user of the parent.
Afterwards, the sandbox will continue as if it was called as a setuid binary.
In addition, this adds new_user_namespace as an option in process_util in order
to set the UID and GID mapping correctly. The reason for this is that just
passing CLONE_NEWUSER to clone_flags doesn't help in LaunchProcess(), because
without setting the mappings exec*() will clear the process's capability sets.
If the kernel doesn't support unprivileged user namespaces and the sandbox
binary doesn't have the setuid flag, the Zygote main process will run without a
sandbox. This is to mimic the behaviour if no SUID sandbox binary path is set.
