This will remove the need to implement compat code handling very old API
versions where some symbols are not available, and it reduces the burden of
dealing with media framework issues around concurrent codec usage that are
worse on older API versions. Top apps that we've surveyed as potential users
for transformer library features are using API 21 or later.

*** Original commit ***
Remove usage of @ForOverride.
Fixes the gradle compilation failures.
Gradle dependencies need revising if we want to be using this, as
checkerframework is ahead of their latest version, such that we
can't compile.

The `GlUtil` wrappers for attributes/uniforms allocate buffers that are passed into OpenGL, and it seems that the distorted output was caused by these buffers being garbage collected.
The issue was difficult to reproduce manually. Add a test that does repeated transcodes in a loop (marked `@Ignore` for now because it runs for a long time and requires network access so may be flaky) to make it easier to run many transcodes and look for inconsistent output. For now the consistency check is just based on the file size which is very likely to change if the actual video frames change.
Verified that the test fails before, and passes once the attributes and uniforms are stored in fields as in this CL.
