[PATCH] IMAP module efficiency improvements

Last summer I sent in some patches to speed up the IMAP module's dealing with large mailboxes. At the time I noted that there were similar problems with other parts of the module, but I didn't have time to fix them then. Since I still see the problems in 4.2.0 (and I've suddenly had a need to improve performance with large #'s of mailboxes), I went ahead and finished the patch for folder lists. The changes to php_imap.c and php_imap.h are attached. Basically the same things that I did to the message list last year. If someone could briefly look these over and commit them that would be very helpful.
