SASL mech removed from backend bind callback (as SASL is managed by frontend)
Changes to some backends are untested (as I don't have all dependent
software install)
and back-ldbm are preserved, they only use the up-cased DNs. back-passwd
uses the mixed-case DN. All others are using mixed-case DN, may need more
fixing.
* Fixed unfree'd 'char *results' in all tcl_* functions (only unfree'd in
certain cases, moved the free to the actual function) so no more mem
leaks. Tested this with over 500,000 access's for testing :)
* Miscellaneous source style and tabulation fixes
