introduction of pid/agrs parameters to the test-suite slapd.conf files;
creation of sub-directory test/var for storage of pid/args files during test;
update of the slapd and slapd.conf man pages.
(The change reduces dependency on ldapconfig.h, since SLAPD_PIDEXT
and SLAPD_ARGSEXT are deleted from the code.)
add/merge as we now free strings agressively. Improved debug
message to include name of missing required attribute and added
check for 'operational attributes'. This check should be used
everywhere we need to test for operational attributes (add/modify).
Also, enabled schema checking for tests (and fixed resulting
problems by adjusting oc.conf).
"Check that the entry has no writers before removing it from the
cache" sounds more sensible to me than "check that it *has* writers"
before removing it.
I've also changed the default cachesize for tests to 4. This
should help discover such problems.
