[Tizen]  Correct namespace for file operation functions inside
package_installer.cc

After upgrade Chromium version to 31.0.1650.12, some file operation functions are
moved from namespace 'file_util' to 'base', including PathExists(),
CopyFile(), DeleteFile() .etc.

This CL is to correct namespace for these functions inside
package_installer.cc.
[Android] Disable disambiguation popup for multiple targets.

XWalk does not use the disambiguation popup when tapping on multiple targets, so
set the renderer prefs to disable it, which is the legacy way of content API.

it's essential.

[Android] Add custom version tag in build.xml for xwalk_core_library

The custom version tag is to prevent the build.xml being updated
by tools like 'android update project'.
It is needed by the cli for xwalk cordova container.

Finish migrating from googleurl/src/gurl.h to url/gurl.h.

Chromium M31 has wiped out the googleurl directory and merged the googleurl
repository into the Chromium one.

I guess the build bots (and the developers' checkouts) kept src/googleurl/
around for some reason and the build did not fail before, but the canaries,
which start from a fresh checkout every time, were failing:

[Tizen] Fix build break caused by new ffmpeg

Tizen 2.x platform have gcc version 4.5 which breaks compilation of new ffmpeg.
Break is caused by pragmas that are used inside functions. This patch modifies
configuration of ffmpeg (chromium/linux/ia32) and disables pragmas.

[Tizen] packaging: Explicitly specify our Python version as 2.7.

Tizen 2.1 (and possible later versions as well) use Python 2.7 instead of
2.6, so pass that to Chromium's python_arch.sh.

We were supposed to pass that ever since we started packaging Tizen, but
there are two things to take into account:

- The CPU architecture in python_arch.sh is only used to special-case some
  stuff for MIPS, so this wasn't impacting us negatively before.

- Things were still supposed to work even if we didn't specify
  `python_ver', but my own commit 211783 upstream has shown a bug in the
  file(1) shipped by Tizen 2.1: `file --dereference /does/not/exist' returns
  0 instead of 1, which made python_arch.sh follow a pathological code path.
