This patch adds a new Chrome-specific dynamic linker for Android,
that implements RELRO section sharing in order to save about 1.3 MB
of RAM per renderer process in content-based programs (ContentShell,
ChromiumTestShell, Chrome, etc...)
The linker is disabled by default. For more details, see the corresponding bug entry.
This introduces a new test package (content_linker_test_apk) as well as a new test category. To build and test this feature, do the following:
ninja -C out/Debug content_linker_test_apk
build/android/test_runner.py linker
