pull up r19009 from trunk

 target_version: 1.6
 tags: pullup

 Some related changes were already in, and I found a couple more to make:

 * ldap_realm.c (ldap_filter_correct): Change string argument to char *.  Delete
 length argument, which was always strlen of the string argument, and compute
 it locally, using size_t instead of (unsigned) int for length-related values.
 Update all calls.

 * ldap_realm.h (ldap_filter_correct): Updated declaration.

 * ldap_misc.c (remove_overlapping_subtrees): Add forward declaration.  Make
 static.
 (is_principal_in_realm): Change local variable defrealmlen to size_t.
 (store_tl_data): Change local variable curr to point to unsigned char, since
 that's what the tl_data_contents array is declared as, and what the STORE16_INT
 macro is happier with.
 (krb5_ldap_get_reference_count): Make local variable i unsigned.
