Summary:                    Buffer overflow when maxmsg not used for IMAP
storage users
Description: 
When users do not have maxmsg set individually, or when maxmsg is not set,
memory allocation and deallocation of the "deleted" and "heard" arrays can
cause a crash.    This patch uses MAXMSG to size these arrays when using
IMAP.  This guarantees that the array will always be big enough to hold all
messages that might be accessed.  This is even more important when using
IMAP quotas instead of message count to limit the number of messages in a
box, and when mailboxes can be accessed directly from an IMAP mail client.
