Leon Scroggins III 4c11945a97 Respect repetition count in SkAnimatedImage
Bug: b/63908092

By default use the repetition count stored in the encoded data (if
any). Allow setting the repetition count manually, so that the
animation will stop after n+1 total cycles (unless -1 is used for
infinite).

If the animation is complete, make start reset it.

When the animation is not running, make update return max double (i.e.
no need to update any time soon).

Fix a bug where the first call to update returned -1.

Share write_bm with CodecAnimTest, for debugging.

Update Sample to check isRunning rather than keeping its own record
of whether the animation is running.
