bug 1438735 - balrog scriptworker push and schedule support. r=bhearsum - add balrog submit-toplevel - this replaces the final portion of the updates builder. - rename balrog transform to balrog_submit, because it's for balrog locale submission - make this default to the 'promote' phase. balrog and beetmover currently take the current phase, which isn't always the wanted behavior. - rename balrog publish to balrog schedule - add balrog secondary push and secondary scheduling, for RCs - remove the release_updates transforms - make the task.py balrog transforms smarter - get rid of the release_balrog_publishing transforms; ad a generic worker_type transform - add BALROG_ACTIONS to scriptworker.py - add get_balrog_action_scope() - remove the unused balrog channel scopes MozReview-Commit-ID: 369ACiOAd5F

# Arguments:
#
# -h - C Header file.
# -a - ASM file.
# -p - Print the options if correct.
# -o - Output file.

# Usage:
#
# # Compare the two configuration files and output the final results.
# ./lint_config.sh -h vpx_config.h -a vpx_config.asm -o libvpx.config -p
