exchange: move bundle specification parsing from cmdutil

Clone bundles require a well-defined string to specify the type of
bundle that is listed so clients can filter compatible file types. The
`hg bundle` command and cmdutil.parsebundletype() already establish the
beginnings of a bundle specification format.

As part of formalizing this format specification so it can be used by
clone bundles, we move the specification parsing bits verbatim to
exchange.py, which is a more suitable place than cmdutil.py. A
subsequent patch will refactor this code to make it more appropriate as
a general API.

    rcs = [os.path.join(path, 'hgrc')]

    try:
        rcs.extend([os.path.join(rcdir, f)
                    for f, kind in osutil.listdir(rcdir)
                    if f.endswith(".rc")])
    except OSError:
        pass
    return rcs

    # old mod_python does not set sys.argv
    if len(getattr(sys, 'argv', [])) > 0:
        p = os.path.dirname(os.path.dirname(sys.argv[0]))
        if p != '/':
