[Android] Clear FLAG_FORCE_NOT_FULLSCREEN when entering fullscreen

The FLAG_FORCE_NOT_FULLSCREEN flag of Android Window will force the
Android system to show status bar, even with SYSTEM_UI_FLAG_FULLSCREEN
set in SystemUIVisibility.

Record whether the FLAG_FORCE_NOT_FULLSCREEN is set before entering
fullscreen and clear it if so. Add the flag back if necessary when
exiting fullscreen.

[Android] Add test case for onReceivedErrorTest().

This patch is to add test case for onReceivedErrorTest().
Open some urls with error format, the resource client will receive
the related error. Verify the error information with the expected
result.
[Android] make_apk: Print an error message _before_ exiting.

Fix the order of the print() and sys.exit() calls so that the error
message is actually printed before the program exits.
[Runtime] Disable extensions api for external web page.

We should only enable extension js api for frame which with
app scheme or file scheme.

Move to M37.0.2062.20

- Skip SIMD command line for now.
- sync gyp_xwalk with gyp_chromium (r274762).
- Fixed the code for the Geolocation. Just like in M36 the delegate
has been refactored. It's now not a separate class to inherit from
but a regular object to instanciate. On other platforms than Tizen and Android
we need to make sure we return with the callback otherwise it hangs waiting for a reply.
As we do not support this on desktop we can just early return false.
- Fix 'screen' property not being replaced in a test : Blink commit 5fdac279
made the 'screen' property non-replaceable, so the only way to overwrite it
now is using v8tools utility to force.
- [Android] Strings now are generated differently through a dedicated GYP target.
- DEPS.xwalk: Start tracking Ozone-Wayland's Milestone-Summer branch.
- [Android] Fix resource packaging : In upstream the resource processing changed a
lot.
-[Tizen] Temporarily disable ALSA support : https://codereview.chromium.org/264973012 introduces a dependency on
ALSA's sequencing interface, which is currently disabled on Tizen.
- [Tizen] Add a patch for angle specific to Tizen to skip the .git/index dependency wrongly added. Fixed upstream
already http://code.google.com/p/chromium/issues/detail?id=395705
[Tizen] Temporarily disable WebRTC support (XWALK-2160)
