More bugfixes in imap4d.

* imap4d/authenticate.c (_auth_try): Fix call to p->handler.
* imap4d/fetch.c (fetch_send_section_part): New argument
close_bracket.
Never print .PEEK, it confuses some clients (notably Thunderbird).
I need to verify RFC, though.
All callers updated.
* imap4d/idle.c: Use imap4d_getline to get the reply, to avod modifying
tok and command.
* imap4d/imap4d.h (util_send_bytes, util_trim_nl): New prototypes.
* imap4d/util.c (util_trim_nl): New function.
(imap4d_getline): Use util_trim_nl.
