mergestate._resolve: handle change/delete conflicts

We will represent a deleted file as 'nullhex' in the in-memory and on-disk
merge states. We need to be able to create absentfilectxes in that case, and
delete the file from disk rather than try to write it out.

import os

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

        # uuid is better, but not available in Python 2.4.
        covpath = os.path.join(os.environ['COVERAGE_DIR'],
                               'cov.%s' % random.randrange(0, 1000000000000))
        cov = coverage.coverage(data_file=covpath, auto_data=True)
        cov._warn_no_data = False
        cov._warn_unimported_source = False
