[Android] Improve error messages for runtime and packaging tool

Fix https://crosswalk-project.org/jira/browse/XWALK-1283 issue 2.
Show x86/arm architectures after building. like below:
WARNING: This APK will only work on x86/ARM based android devices"
Consider building for ARM/x86 as well.
[Application][Extension][Runtime] Merge xwalk-launcher with extension process in service mode

With this update when running in service mode, XWalkExtensionProcess will be
bootstrapped by launcher instead of runtime daemon.

This improvement has several advantages:
1. Some Tizen Device APIs binding with AUL can be directly called in launcher,
instead of passing request through IPC.
2. Less process number for an application, the system footprint will be smaller.

Implementation details:
Once a XWalkExtensionProcessHost is created, it will notify corresponding running
application's DBus object to send a signal to its launcher. Then launcher will
retrieve the created IPC channel and instantiate a XWalkExtensionProcess.

We don't care about Tizen 2 anymore, and the referenced files do not even
exist anymore.

Move to Chromium 35.0.1916.17.

This is another one of those big commits made of a lot of smaller squashed
commits done in our "next branch".

Some of our tests are broken but pass in Release mode; we are working on
fixing them.

Most of the changes in the code are caused by upstream Chromium changes,
namely:

Additionally, the following commmits are worth mentioning:

  M35 gardening: stop passing --fatal-warnings to ld on Tizen Common.
  XWALK-1379 is tracking this. There are linkage failures because of
  sqlite3 symbols used by libpkgmgr-info.so and libpkgmgr_parser.so.

  [Tizen] Remove Mesa patch that's not needed anymore.
  This was fixed differently upstream with r255915 in Chromium.

  Sync gyp_xwalk with upstream gyp_chromium
  Synced to revision r258119.

  [Android] Fix core shell crash issue after rebasing to Chromium35
  icu_use_data_file_flag has been enabled on Android after Chromium35.
  Need to package icudtl.dat resource.
  TODO:
  1. It will also be crashed on Shared mode, caused by application context issue.
  2. CoreShell will be crashed when exit. Will track with XWALK-1366.

[Android] Provide embedding API for Crosswalk.

A new embedding API is designed for providing capabilities to embedders.
This can provide functionalites and their APIs as an Android library.
This patch mainly re-define API and re-construct classes and their
relationship. To keep current capability, lots of legacy code are also kept
without big changes. Main changes are:
1. New APIs: XWalkView, XWalkUIClient, XWalkResourceClient, XWalkPreferences,
XWalkNavigationHistory, XWalkNavigationItem and XWalkJavascriptResult.
2. Legacy APIs are used by tests. Need to refine them.
3. Remove unused code for http authentication.
4. Re-construct some duplicated code in core tests.
This issue is still for XWALK-1041. It's not finished yet. Need to implement
remaining TODOs and refine the description of APIs.

[Linux] Add NaCl support

Based on NaCl component work (http://crbug.com/244791) from upstream,
this commit is to add Native Client(aka NaCl) support.
It now can run examples from nacl sdk.
  $ cd <nacl_sdk_dir>/pepper_canary/example
  $ TOOLCHAIN=newlib make serve
  $ xwalk http://localhost:5103

Next steps:
 * Enable PNaCl
 * Enable on Tizen

BUG=XWALK-1338
