ldap_timeout setting is unused?

[elliefm]

Instead, ldap_time_limit is used for both timeout and time limit:

$ack IMAPOPT_LDAP_TIMEOUT
lib/imapopts.h
194:  IMAPOPT_LDAP_TIMEOUT,

lib/imapopts.c
1020:  { IMAPOPT_LDAP_TIMEOUT, "ldap_timeout", 0, OPT_INT,

$ack IMAPOPT_LDAP_TIME_LIMIT
ptclient/ldap.c
464:    ptsm->timeout.tv_sec = config_getint(IMAPOPT_LDAP_TIME_LIMIT);
482:    ptsm->time_limit = config_getint(IMAPOPT_LDAP_TIME_LIMIT);

lib/imapopts.h
193:  IMAPOPT_LDAP_TIME_LIMIT,

lib/imapopts.c
1015:  { IMAPOPT_LDAP_TIME_LIMIT, "ldap_time_limit", 0, OPT_INT,

Not sure how this interacts with a service-specific interpretation of "ldap" + "timeout" (but, we don't provide an ldap service, so I guess maybe it doesn't).

These two settings both have the same default value, which might explain how this has gone as long as it has without being noticed
