[Android] Add test case for handling wtai uri

wtai is a standard w3c defined at http://www.w3.org/wiki/UriSchemes/wtai.

BUG=https://crosswalk-project.org/jira/browse/XWALK-321
[Android] Fix crash issue caused by the download listener.

This is because the XWalk core uses the request API to download
local file in the case, which would cause the crash.

So when downloading the local file, download listener would
only do the file transfer for this.

Use 'virtual' and OVERRIDE to fix Mac build

Build on Mac (with Chromium's clang plugin) requires that overrides use
the OVERRIDE macro, and that we always explicitly declare functions as
virtual even if they would implicitly be.
[Application] No need to explicitly Delete() a ScopedTempDir

In destructor for the tests, we don't need to explicitly call
ScopedTempDir::Delete() for our instance, since it will be immediatly
destroyed, and the destructor already calls Delete().

This was breaking build on Mac because the Delete() function uses
WARN_UNUSED_RESULT and Clang was catching it.

[WiDi API] Fix the issue for the relative url passed to requestShow.

If a relative url is passed to requestShow, the page can not be opened correctly.
Fix it by resolving the url with base url to make it to be an absolute one.

[Tizen][UI] Move TizenSystemIndicator to tizen/mobile/ui/

Move system indicator view and its helpers to tizen/mobile/ui/. The
rationale is that tizen/mobile/ directory stores components that are
self-contained and Tizen mobile specific.
[Extensions] Fix regression, extensions not being registered on Tizen and Android

RegisterInternalExtensionsInServer should have been renamed for Tizen and
Android and not only for desktop. The extensions were not being registered
because of that for these platforms.

Thanks to Jesus Sanchez-Palencia for pointing the directions.

[Packaging] Change the way we pass BUILDDIR_NAME to gyp and make.

The M32 Chromium rebase ended up causing a regression in the incremental
Tizen builds: even with no changes, an incremental build would always
trigger a regeneration of most of the V8 bindings in Blink, which then
caused an almost full rebuild of Blink itself.

This was caused by changes in Blink's Source/bindings/derived_sources.gyp,
which were generating some file lists that were dependencies for some
targets in the source tree itself. Since the source tree is erased in every
build, the file lists are regenerated and trigger all those rebuilds.

Fix this by pulling some commits that had to be made in Chromium and gyp
itself to properly support passing an absolute directory to gyp's
--generator-output option and then using that to know where to store the
file lists generated by gyp:

  Chromium r236822: Pass the gold binary to the linker using only absolute
                    paths.
  gyp r1797:        make: Support the generator_filelist_paths input info.

Now, instead of passing "builddir_name" when calling make, we pass --depth
and --generator-output to gyp.

While we could backport this commit to the crosswalk-2 branch, there isn't
really a need for that, as the previous process was working fine with M31.

[Tizen] Permit the inclusion of Tizen Web UI Framework

This patch creates a Tizen-specific XWalkContentRendererClient that
implements the WillSendRequest hook.  This hook, as the name implies, is
called before every request is made from a particular WebKit::WebFrame.  By
tapping into this hook, it is possible to rewrite requests so that they have
the full file path.

Some measures are taken so that relative paths outside where the Tizen Web
UI Framework can't be referenced; also, only known extensions are permitted.
