We have definitions for a number of properties both from the WSP
spec document and from those used by wireshark. These properties
are built into samba (generated from csv files). This commit allows
extra properties to be added on the fly in a custom csv file, the
format of the csv file is the same as that used in the build. This
allows us to add some 'unknown' properties on the fly, although we
would hope that information regarding these properties would be
incorporated into the build in due course.

wsp_util.c contains property definitions for well known windows
properties that can be used with WSP. These properties are generated from
some csv files (located in the librpc/wsp). The csv files themselves
were generated from a couple of sources e.g. the [MS-WSP]:
Windows Search Protocol document and wireshark mswsp dissector source code.
for more details please see librpc/wsp/README

‘bool_value’ has the same type as ‘uint_value’. Removing the former

A consequence of this is that we remove the confusing "length"
from the IDL, as it was the internal UTF8 length, not a wire
value. We use null terminated strings internally now.

Almost always the ACE has an `ignored` DATA_BLOB as the coda, and the
length of the coda is the length field of the blob, which is usually
zero.

A security token contains the context needed to make access decisions
for a particular client, which has until now been a number of SIDs and
flags. Claims are arbitrary attributes that can be tacked onto the
security token. Typically they will arrive via a Kerberos PAC, but we
don't need to worry about that now -- only that they are stored on the
token.
The security token in [MS-DTYP] 2.5.2 is described in abstract terms
(it is not transmitted on the wire) as behaving *as if* it held claims
in three arrays of CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1 structures. We
take that suggestion literally. This is *almost* the same as storing
the [MS-ADTS] 2.2.18 claims wire structures that the claims are
presumably derived from, and doing that might seem like a small
optimisation. But we don't do that because of subtle differences and
we already need CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1 in security.idl
for resource attribute ACEs.
The three stored claim types are user claims, device claims, and local
claims. Local claims relate to local Windows accounts and are unlikely
to occur in Samba. Nevertheless we have the array there just in case.
