dispatch: add fail-* family of hooks

The post-* family of hooks will not run in case a command fails (i.e.
raises an exception). This makes it inconvenient to hook into events
such as doing something in case of a failed push.

We catch all exceptions to run the failure hook. I am not sure if this
is too aggressive, but tests apparently pass.

#!/usr/bin/env python

import errno, os, sys

for f in sys.argv[1:]:
    try:
        print f, '->', os.readlink(f)
    except OSError as err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
