/*----------------------------------------------------------------------
new_mail() - check for new mail in the inbox
Input: force -- flag indicating we should check for new mail no matter
time_for_check_point -- 0: GoodTime, 1: BadTime, 2: VeryBadTime
flags -- whether to q a new mail status message or defer the sort
Result: returns -1 if there was no new mail. Otherwise returns the
sorted message number of the smallest message number that
was changed. That is the screen needs to be repainted from
that message down.
Limit frequency of checks because checks use some resources. That is
they generate an IMAP packet or require locking the local mailbox.
(Acutally the lock isn't required, a stat will do, but the current
c-client mail code locks before it stats.)
Returns >= 0 only if there is a change in the given mail stream. Otherwise
this returns -1. On return the message counts in the pine
structure are updated to reflect the current number of messages including
any new mail and any expunging.
