Merge pull request #2177 from wang16/revert_test

Revert "[Android] Add test case for onReceivedErrorTest()."
[Extension] Implemented bulk data transmission enhancement feature.

Inspired by Thiago Marcos P. Santos <tmpsantos@gmail.com>

Enhanced the feature of postMessage from extension to renderer process
by introduced shared memory when transmitting big bulk of data, also
used a threshold kInlineMessageMaxSize to control if we need to use
shared memory or IPC message.

If the message to post exceeds the threshold, we will create a shared
memory to wrap the message and post the shared memory handle instead;
in the receiver process we'll restore the message from the received
shared memory and process it as before.

[Android] Fix crash caused by calling pauseTimer twice in row

The timer is actually global in current implementation.
Use a static boolean to record the status to avoid duplicated
calling pauseTimer().

[Runtime] Support launch an url from launcher.

After commit 4f4eca4773e7e4a98dc0198fdca1bae1886c749e

We always compile a Shared Process Model binary for
tizen, and it always run as shared process model, so we cannot
launch a page with url like 'xwalk http://www.google.com'.

There is an easy way that we can support launch an url from
launcher, and create an temp app for url.
