704bbae25c source4 dsdb: Allow duplicate non local objectSIDs
Remove the unique constraint on the objectSID index, and enable the
unique_object_sids module.

This allows duplicate objectSIDs on foreign security principals, and
disallows duplicates for local objectSIDs

8eb95bc1d1 schema_set: Add comment about set schema from ldif in a transaction
This is normally called with a transaction or before access is shared.
The python code and some tests may also cause an issue, but as these are
fixed at runtime, this is only a temporary issue that resolves itself.

17f1c6f9f4 schema: Make writing indices flag an enum for a new state
In schema_load_init, we find that the writing of indices is not locked
in any way. This leads to race conditions. To resolve this, we need to
have a new state (SCHEMA_COMPARE) which can report to the caller that we
need to open a transaction to write the indices.

5d404eaeab Do not re-use the attribute @IDXVERSION for SAMDB_INDEXING_VERSION
Confusing these two concepts is not a good idea, SAMDB_INDEXING_VERSION refers to
a change in a Samba rule to canonicalise one of our attributes, not the
in-DB index format.

As we already change @INDEXLIST in this version, this commit
is at no extra cost.

effac54893 dsdb: Set that Samba uses the GUID index in LDB
This is optional, but only to aid the downgrade script (and in case
there is some major issue found with it).  We don't support that mode,
as that would require us to test and maintain multiple code paths and
not optimise queries to be GUID centric.

2a90606417 dsdb: Remove 120 second delay and USN from schema refresh check
We now refresh it once the schema changes, so that replication can
proceed right away.  We use the sequence number in the metadata.tdb.

The previous commit added a cache for this value, protected by
tdb_seqnum().

metadata.tdb is now opened at startup to provide this support.

Note that while still supported, schemaUpdateNow is essentially rudundent:
instead, to ensure we increment the sequence number correctly, we unify that check
into repl_meta_data at the transaction close.
