Create an unified binutils source tree for both Android and ChromiumOS.

About source code - The base version of this binutils is newer than that
of aosp/binutils-2.25, it is based on the binutils that is used to build
google products and ChromiumOS. And it contains *all* local Android
patches as well as all patches that are cherry-picked from upstream for
aosp/binutils-2.25 tree (up to Nov. 5 - 932d71b85). You may find the
detailed development history for this binutils tree here -
https://chromium.googlesource.com/chromiumos/third_party/binutils/+log/unification
(This CL is a combination of all the CLs in it. After this CL is
submitted the tree will be identical to
https://chromium.googlesource.com/chromiumos/third_party/binutils/+log/unification
at 2865a3615d80bd5f82d14d7e0484e84dc052596a)

About testing - We tested this binutils for both ChromiumOS and
Android. For android, we tested building N4, N5X, N6, N7, N9 using new
binutils, we also did a full-build of toolchain (by build.py) and built
a N5X image; for ChromiumOS - it passed ChromiumOS toolchain release
tests on all 4 platforms (x86, x86_64, arm32 and arm64).
