Increase POPBUFSIZE and check for overflow

I recently needed to use Microsoft Exchange, and followed the very helpful
instructions at https://www.claws-mail.org/faq/index.php/Oauth2 . One of the
issues I encountered was that the Oauth2 access tokens used can be larger than
one of the buffers used to store them. The largest token size I saw was 3636
bytes, but pop3_gen_send silently truncates these tokens to POPBUFSIZE=512
bytes .

I've attached the patch that I use to increase POPBUFSIZE and warn when there
is an overflow.
