Add chromiumviews library on Linux
Add patch to allow restarting of renderer process on purpose.
Add patch to turn sandbox error message to warm warning.
Add patch to disable renderer hang monitor when page is unloading.

We're doing some GUI work like asking for confirmation in the
beforeunload handler, so it's very likely that the renderer may seem
unresponsive. The default behavior of chromium is to close page, which
is of course not the thing we want.
Add patch to expose necessary members of URLRequestJob.
Add patch to expose "File" class's "path" attribute.

Add patch to suppress warning of CFAllocator.
Add patch to make iframe sandboxed by default.
Add patch to allow Ctrl+Alt accelerators on Windows.
Do not contain the Debug build in distribution.

It would saves a lot of time when uploading & downloading on a slow
network, and in the atom branch the debug build is not actually used
too.
