When querying the imap mailbox for all messages with UID in [1,inf],
isync currently hardcodes the upper limit to 1000000000, which can
actually be exceeded, which results in missing messages on the slave.
This is not merely theoretical: I missed a message with UID=1343495243
just now; and after raising that limit to 2000000000, I got all my
missing messages sync'ed successfully:

But this is only a quick and dirty workaround: what if the UID exceeds
2000000000? By packet sniffering, I found Outlook Express using the
IMAP command `UID FETCH 0:*', which seems a reasonable way provided that
UIDs returned by the server does not overflow the integer type isync
uses for these numbers.
Any idea on this issue?
