* Look for a specific mailbox, creating it if necessary, and return the mailbox id.
* This is a blocking operation and should not be called from the UI thread.
*
* Synchronized so multiple threads can call it (and not risk creating duplicate boxes).
*
* @param accountId the account id
* @param mailboxType the mailbox type (e.g. EmailContent.Mailbox.TYPE_TRASH)
* @return the id of the mailbox. The mailbox is created if not existing.
* Returns Mailbox.NO_MAILBOX if the accountId or mailboxType are negative.
* Does not validate the input in other ways (e.g. does not verify the existence of account).
