[Android] Add NFC to permission mapping table.

By this, user can use make_apk.py to package their application
with NFC extension with correct permission, for example:
$ python make_apk.py --name=apkname --package=org.xwalk.example
  --permissions=nfc --extensions=...

[Android] Fixed that long press on text will crash in shared mode

The ActionMode will use Activity to inflate layout, which in
shared mode, it will fail due to incorret context to search
for resources.

Introduce XWalkActivity for Embedders who want to use Shared
mode to inherit for the Activity will contain SharedXWalkView.

Besides, some layout ids exist in both app and library context.
Add detection of whether the stack trace is from library or
app to try use the correct resource first.

[Android] Fix the accessibility problem of reflection helper

In wrapper type of reflection, getBridge method is not
public for document generating. This causes potential
accessibility problem when converting wrapper type to
bridge type. So in reflection helper, if the method to
be invoked is not accessible, enable it temporarily and
reset the status after invoked.
[Android] Generate resource maps for internal packages

The resource maps are removed from upstream commit 866abeb.
Crosswalk need these resources entries to resolve the
conflict of how Resource Ids generated between gyp build
system and ant build system.
Generate resource maps from generated R.javas by crosswalk
self now.

DEPS.xwalk: Roll chromium-crosswalk (4e78cd0 -> 88fc58a).

4adebb3 [Backport] Allow forcing TestWebServer to use a specific port number.
0622b0f [Backport] Start server thread in new TestWebServer.start() method rather than constructor

This roll requires changing several Android tests because
TestWebServer's API in Chromium has changed (we would need to do this
anyway when moving to M40). The changes are pretty much the same ones
that were done in Chromium commit c28e68d ("Start server thread in new
TestWebServer.start() method rather than constructor").

BUG=XWALK-2755
[Android] Hardcode the port number the CORS tests use.

In M39, TestWebServer chose a random open port to listen in, but for our
CORS+XHR tests we need it to be listening in a specific port that we
then fetch via XHR.

This fixes org.xwalk.runtime.client.test.CrossOriginXhrTest and
org.xwalk.runtime.client.embedded.test.CrossOriginXhrTest.

[Android] Temporarily disable some Core tests.

Disable OnFullscreenToggledTest, OnRequestFocusTest and
OpenFileChooserTest.

They have started failing due to
https://codereview.chromium.org/516753002 and
https://code.google.com/p/chromium/issues/detail?id=407643, and fixing
them will likely require getting some patches upstream.

While we do that, let's get the tests back to green to avoid letting
other regressions creep in.
