  ASTERISK-18067 ASTERISK-15479 - White Space affects mailbox value, multiple MWI subs

  Before, having multiple subscriptions to mailboxes on a sip peer set via the mailbox
  setting in sip.conf would only result in updates being sent on whichever mailbox
  triggered the mwi event.  Now all of them get counted regardless.  Also fixes a bug
  involving parsing of the mailbox option in sip.conf so that trailing and leading
  spaces before/after commas are trimmed.
