Bug description:  ldap_modify, ldap_add, ldap_mod_replace all hang with large arrays

Description:
------------
ldap_modify, ldap_add, and ldap_mod_replace all hang when they attempt to
adjust an individual attribute with data roughly 31k characters or
greater.  There is a threshold such that 30k and below works fine and 35k
and above never works.  Example:

$attrs = array();
$attrs['mnappparam'][0] = "tmpalkkllk...";
# strlen($attrs['mnappparam'][0]) is 32000
ldap_mod_replace($conn, $dn, $attrs);
# we hang, but if $attrs['mnappparam'][0] is 31000 or less, # we work.

It should be noted that cut-n-pasting (and modifying a little) and then
attempting to use ldap_modify (commandline), the entry works, no matter
how large.  (Thus, definately a PHP bug.)  






Reproduce code:
---------------
$attrs = array();
$attrs['mnappparam'][0] = "tmpalkkllk...";
# strlen($attrs['mnappparam'][0]) is 32000
ldap_mod_replace($conn, $dn, $attrs);
# we hang, but if $attrs['mnappparam'][0] is 31000 or less, 
# we work.



Expected result:
----------------
It just hangs.
