mail: add parseaddrlist() function for parsing many addresses at once
Adds a new function addrlistencode() to mercurial.mail, like addressencode(),
but accepts a list of addresses as input, and returns a list of formatted
addresses. This will be used by patchbomb.
The difference is that each element in the input list can contain multiple
addresses (comma separated or otherwise), and are split using Python's
email.Utils.getaddresses().
