We search in the schema if we have already this intid (using dsdb_attribute_by_attributeID_id because
in the range 0x80000000 0xBFFFFFFFF, attributeID is a DSDB_ATTID_TYPE_INTID).
If so generate another random value.
If not check if the highest USN in the database for the schema partition is the
one that we know.
If so it means that's only this ldb context that is touching the schema in the database.
If not it means that's someone else has modified the database while we are doing our changes too
(this case should be very bery rare) in order to be sure do the search in the database.

Samba 4 use to try to reload the schema every time dsdb_get_schema was
called (which could be 20+ time per ldb request). Now we only reload at
most every xx seconds (xx being the value of dsdb:"schema_reload_interval"
or 120). The timestamp of the last reloaded schema is kept in the
dsdb_schema object. There is also a timestamp in the ldb_context, that
is used by the LDAP server to know if it has to reload the schema after
handling the request. This is used to allow that the schema will be
immediately reload after a schemaUpdateNow request has been issued, the
reload can't occur in the handling of the LDAP request itself because
we have a transaction autostarted.

"servicePrincipalName"s more than once
The service principal names need to be case-insensitively unique, otherwise we
end up in a LDB ERR_ATTRIBUTE_OR_VALUE_EXISTS error.
This issue has been discovered on the technical mailing list (thread:
cannot rename windows xp machine in samba4) when trying to rename a AD
client workstation.

First they do not need to be "static" any longer since we have abandoned
asynchronous result handling (where global variables have been important).
In addition add some "const" in order to protect us from unwanted writes.

This is a very essential attribute since it references to various domain
master roles (PDC emulator, schema...) depending on which entry it has
been set. Incautious modifications can cause severe problems.

We don't need to compare the delete against the primaryGroupID check
here - that test is for adds.

the samldb checks failed to account for the possibility of a member
being removed and added in the same modify operation. This happens
(for example) when dbcheck is fixing a SID in a DN.
The repl_meta_data.c code already has this check, it just wasn't
giving the right specialised error code for the 'member' attribute

This was only used by the Fedora DS backend for Samba4. We agreed to

Older AD deployments simply don't have it and hence there is no RODC
support.

Ekacnet was not quite right yet but his patch made me think further.
This primary group changing is only needed if the account type changes.
With this patch we do one more search if the "userAccountControl"
changes but we save us from doing these unneeded and wrong modify replace
operations most of the time.
