debugcommands: move 'debugrevlogopts' into the new module

This move contains the first reference to debugrevlogopts in
debugcommands.py. We'll eventually want to move that over. We
hold off for now because it would introduce a module import cycle.

from __future__ import absolute_import
import os

if os.environ.get('COVERAGE_PROCESS_START'):
    try:
        import coverage
        import uuid

        covpath = os.path.join(os.environ['COVERAGE_DIR'],
                               'cov.%s' % uuid.uuid1())
        cov = coverage.coverage(data_file=covpath, auto_data=True)
        cov._warn_no_data = False
        cov._warn_unimported_source = False
        cov.start()
    except ImportError:
        pass
