We only ever use the principal comparison functions to check equality.
Having these functions only handle equality simplifies their
implementation and makes them a bit easier to use.

The existing implementation did not differentiate between the case where
the relevant component was not present, and that where talloc_strndup()
failed. To correct this situation, put the result into an out parameter
on success and return an error on failure.

Consider the non-conforment utf-8 sequence "\xf5\x80\x80\x80", which
would encode 0x140000. We would set the high byte of the first
surrogate to 0xd8 | (0x130000 >> 18), or 0xdc, which is an invalid
start for a high surrogate, making the sequence as a whole invalid (as
you would expect -- the Unicode range was set precisely to that
covered by utf-16 surrogates).

At present, if we meet a string like "hello \xed\xa7\x96 world", the
bytes in the middle will be converted into half of a surrogate pair,
and the UTF-16 will be invalid. It is better to error out immediately,
because the UTF-8 string is already invalid.

This shouldn't happen -- that is, there should never be non-tombstone
records in conjunction with a tombstone record -- and if it does, the
situation should resolve itself here. But the flow is confusing and
strange things sometimes happen often enough that it would be helpful
to know if this ever occurs.

Add support to parse AQS-like (Advanced query syntax)
AQS - see https://learn.microsoft.com/en-gb/windows/win32/search/-search-3x-advancedquerysyntax
The basic (AQS) syntax is supported e.g. a query is built of a sequence of
queries connected by AND, OR and NOT where the query elements are
essentially restrictions defined by a property. There are some
limitations on the operators supported[1] and additionally some things
like enumerated ranges are not supported at all and range values are not
delimited as specified [2]. Some special cases that you see in the
windows search UI are exceptions [3] which are handled more or less as keywords
Some examples:
The following are all exactly the same query just expressed using
different variations of the syntax
'ALL:($<p403 OR $<p404) AND System.Kind:picture AND Scope:"FILE://somemachine/someshare" AND > System.Size:10241-102401'
'ALL:$<p403 OR ALL:$<p404 AND System.Kind:picture AND Scope:"FILE://somemachine/someshare" AND > System.Size:>=10241 AND System.Size:<102401'
'ALL:$<p403 OR ALL:$<p404 AND System.Kind:picture AND Scope:"FILE://somemachine/someshare" AND > System.Size:small'
The queries above by default select the property System.ItemUrl as the
one and only column returned, the query parameter however accepts a
variation to the AQS like syntax to allow arbitrary columns to be
selected e.g.
'SELECT System.ItemName, System.ItemURL, System.Size WHERE ALL:$<p403 OR ALL:$<p404 AND System.Kind:picture AND Scope:"FILE://somemachine/someshare" AND System.Size:small'
[1] supported operators
-------------------
= Equals
!= Not Equals
> Greater than
< Less than
>= Greater than or equals
<= Less than or equals
$= equals
$< starts with
[2] ranges are specified as value-value instead of value..value (seems
my flex/bison skills are not good enough and couldn't get that to
work with '..'
[3] The windows UI has shortcut ranges (presumably represented as enumerated
ranges) providing date ranges like 'today', 'tomorrow',
'lastweek' etc. and similarly sizes like "empty, tiny, small, large..."
These are supported (but implemented as keywords)

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.
