vfs: add a `_auditpath` to abstract vfs

We are about to make `rename` audit path. Since rename lives in the
`abstractvfs` layer, we need it to be aware of auditing to some extent.

The default implementation is no-op because multiple existing vfs are not using
auditing at all right now (eg: fncachevfs).

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()
