[Tizen] Remove crosswalk manifest entry for not existing xwalk binary

[Tizen] Add negative debugging port number handling

BUG=XWALK-2708
Move Chromium 39.0.2171.19, the first M39 beta.

Most of the commits were just gardening ones to adapt to file location
and API changes in Chromium.

Additional changes worth noting:

* SIMD.js support is temporarily disabled as we always do when switching
  to a new Chromium milestone. XWALK-2734 is tracking this.

* NaCl support had to be disabled for Tizen 32-bit builds because Google
  does not ship a 32-bit NaCl toolchain anymore. XWALK-2679 is tracking
  this.

* We're now tracking Ozone-Wayland's Milestone-Autumn branch.

* Java 7 is now required to build Crosswalk for Android, following the
  requirements from Chromium itself.

* On Tizen, we don't set enable_ozone_wayland_vkb and enable_xdg_shell
  anymore. Since ozone-wayland commit aeb6a5f7 they do not have any
  effect, and one is expected to define whether those features are
  enabled or not with environment variables. We were already setting
  OZONE_WAYLAND_USE_XDG_SHELL in the systemd service file; we now set
  USE_OZONE_WAYLAND_VKB as well.

[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.
