cc: Require high-res tiles for activation after entering NEW_CONTENT_TAKES_PRIORITY mode.

Once we enter NEW_CONTENTS_TAKES_PRIORITY mode, visible tiles on active
tree might be freed. We need to set RequiresHighResToDraw to ensure that
high res tiles will be required to activate pending tree.

[webcrypto] Update to use the KeyAlgorithm.

The WEBCRYPTO_HAS_KEY_ALGORITHM ifdef will be introduced by https://codereview.chromium.org/179353002/ on the blink side. 

This patch needs to land first in order to make the API changes on blink side without breaking the build. Sigh for non-atomic blink/chromium commits.

[Android] Slightly faster findbugs

This calls findbugs.jar directly without the findbugs script.
It is a preferred way to launch findbugs according to
http://findbugs.sourceforge.net/manual/running.html#d0e503
Doing so avoids 'escaping' and 'shifting' each and every of
Chrome .class parameter passed in the 1.5M command-line.

It results in ~8x speed up (0m59s vs 8m16s).

TEST=compared results of findbugs with and without this patch.
