1c3a8fa20c auth: Correct primary group handling
Heretofore we have treated the primary group SID specially, storing it
in a fixed position as the second element of the user_info_dc->sids
array, and filtering out other copies in the PAC_LOGON_INFO base
structure. This filtering has made it difficult to distinguish between
the case where the primary group is a universal or global group, located
in the base RIDs, and the case where it is a domain-local group, missing
from the base RIDs; especially since the attributes of a domain-local
primary group are lost by being stored in the PAC. Domain-local primary
groups are normally disallowed by Windows, but are allowed by Samba, and
so it is reasonable to support them with at least some measure of
consistency.

The second element of user_info_dc->sids is still reserved for the
primary group's SID, but we no longer filter out any other copies in the
array. The first two elements are no more than the SIDs of the user and
the primary group respectively; and the remaining SIDs are as if taken
without modification from arrays of SIDs in the PAC. user_info_dc->sids
should therefore become a more faithful representation of the SIDs in
the PAC. After adding resource SIDs to it with
dsdb_expand_resource_groups(), we should have a result that more closely
and in more cases matches that of Windows.

e20067c52d auth: Make more liberal use of SID index constants
Arrays of SIDs are handled not fully consistently throughout the

anything in particular. Using these index constants in situations of the
former sort can help to clarify our intent.

6a10e890a0 CVE-2022-2031 auth: Add ticket type field to auth_user_info_dc and auth_session_info
This field may be used to convey whether we were provided with a TGT or
a non-TGT. We ensure both structures are zeroed out to avoid incorrect
results being produced by an uninitialised field.

6029e2250c s4-auth: For LDAP simple bind, fall back to checking the ENCTYPE_AES256_CTS_HMAC_SHA1_96 if stored
Since we don't store a salt per-key, but only a single salt, when we do
not have the NT hash in the unicodePwd (eg ntlm auth = disabled), the check
will fail for a previous password if the account was renamed prior to a
newer password being set.

Tree-wide spellcheck for some common misspellings.

source3/utils/status.c has misspelled local variable (unkown_dialect).

"missmatch" is a known historical misspelling, only the incorrect
misspellings are fixed.

source3/locale/net/de.po has the spelling error (unkown) in two msgids -
it probably should be updated with current source.

The optional user_info->orig_client.{account,domain}_name are
