Angle's existing GN files only work in Chrome, so I've written a new one.
This won't work on Windows, but our GN build doesn't work on Windows anyway. So this CL is an attempt to get a ahead of that curve on ANGLE. It looks large but fairly straightforward.
Now working on Linux:
$ gn gen angle --args=skia_use_angle=true
$ ninja -C angle
$ angle/dm --config angle-gl --src gm -w dm-out

Uh, so hey, I just noticed that while the CommandBuffer Test bot runs
with --config commandbuffer, the Perf bot just runs as a vanilla GPU bot.
Shouldn't we pass --config commandbuffer?

Android API >= 24 implies Vulkan support, so we can have a more useful default here than 'false'. If for some reason you wanted to turn it off, you can still override skia_use_vulkan.
The defined(ndk_api) guards other users of our GN files (Fuchsia) who may not have an ndk_api argument defined in their BUILDCONFIG.gn.

These were intended to prevent GN and GYP Android bots from stomping on
each other. Turns out, they don't, even without this... they're writing
most files to completely separate paths:
- GYP puts most data under $EXTERNAL_STORAGE, generally /sdcard
and its binaries (libdm.so, libnanobench.so, libskia.so, skia_launcher)
in /data/local/tmp;
- GN puts everything under /data/local/tmp, and its binaries (dm, nanobench)
don't overlap GYP's.
So clearing /data/local/tmp was essentially just removing GN's data; GYP's
data file caching was never affected and can't conflict with GN's.

Just to take inventory of which old problems still linger and which are now moot, I've gone out of my way to have this stand alone. All of gn_android_flavor's logic is self contained, without any dependency on the platform_tools scripts.
The tricky bits turn out to be, copying directories containing symlinks---or really any copying involving more than one file---and getting the exit code back from adb shell. Luckily the ADB I've got on my desktop and my Nexus 5x seems to handle this all without the awkward workarounds you see here, so there's hope that One Day Soon the weird parts (basically, anything with inline python) can go away. Once we've got these bots landed green, I'll go see whether the fixes are due to ADB updates, Android updates, or perhaps something else like hardware.
The parts marked TEMPORARY are a nod to the fact that the devices are used by gn_android_flavor and android_flavor both today. It's mostly about not stepping on each other's toes or leaving anything laying around that might confuse each other. The marked parts can go away when bots are either gn_ or non-gn_ but not both.
I have omitted a few steps that may be important, but which are easy independent follow-ups:
- running as root
- locking clocks
- waiting on battery levels
- fancier wait-for-ready than adb wait-for-usb-device
It'd be nice to, e.g., reaffirm that locking clocks helps perf stability, and that we're locking to the best policy. I've tried to keep this CL as trim as possible, leaving any of these vaguely optional steps for later.
As of PS 41 or so, it looks like the trybots are all behaving as expected.
We should expect no new images in Gold. Can we see trybots in Perf yet?

Attempt to take over all *SAN builds.
MSAN has a lot of coordination required between gn/BUILD.gn and gn_flavor.py.
I'd like to follow up to move more of this into gn/BUILD.gn, to make it easier
to use locally.
The compile steps should be much faster now. We no longer build CMake
and Clang for every run, instead using the clang_linux CIPD package. This
removes the need for all the third_party/externals/llvm/... dependencies.
Similarly, since we're using the clang_linux package, we no longer depend
on Chrome's Clang, and thus no longer need to sync chromium on these bots.
Instead of packaging up MSAN libraries and llvm-symbolizer in the compile
output, I have the test / perf bots also depend on the clang_linux package.
These do not vary from build to build.
No more need for the xsan.blacklist -include hack: Clang, GN, and Ninja
all track changes to xsan.blacklist without our help.
This has the incidental effect of upgrading the compiler used by *SAN
bots from Clang 3.8 to Clang 3.9.
