patchbomb: fix parsing of multiple addresses, allow multiple addrs in --to/cc/bcc

Instead of using custom code to split apart addresses, we now use
mail.parseaddrlist() which always does the Right Thing as it relies on Python's
email.Utils.getaddresses().

Previously, 'hg email --to=foo,bar' only respected foo and discarded bar. Also,
commas in names were not allowed in hgrc or the interactive prompt; specifying
'"Lastname, Firstname" <foo>' would confuse patchbomb.

The testcase uses '-m tmp.mbox' because -n (like in other tests) would disable
address mangling.
