If the database does not conform to any known schema, make it possible
to edit such a database using slapmodify when schema-checking is
disabled.

Log the same pointer in queue_csn as graduate_

Prevent spurious contextCSN generation
and ignore consumers when we have no contextCSN yet.
But make sure to propagate valid contextCSN updates to
accesslog/syncprov for delta consumers.

Windows mutexes are recursive so the trylock test will succeed
even though the mutex is already locked. Just compare be pointers.

Schema parsing ignores some slapd.conf rules

config_fp_parse_line processes backslash escapes. When existing rewrite
rules were reloaded while inserting a new rule, this caused backslashes
to be lost from every rule except the most recently inserted one.
config_parse_ldif performs similar splitting, but leaves backslashes
alone.

Only usable if backend supports txns

Dynamic startup was failing

This appears to be cruft leftover from rev e8c58b4e

syslogd always overrides the timestamp, so just omit it
Don't use *printf if we don't need to.

Experimental - write 500 updates per txn instead of 1:1

If dds is present early in the overlay stack, the modify ops from
dds_expire can trigger other overlays before they have initialized.
Avoid that by delaying the first expiry until startup has finished.

Limit the number of pwdFailureTime stamps to record, regardless
of lockout settings.

From ITS#5940. Add path has the same code.
