SIP filters

[Jason Etheridge]

Depends on bug 1989478

squashed: https://git.evergreen-ils.org/?p=working/SIPServer.git;a=shortlog;h=refs/heads/collab/phasefx/sip-redaction-squashed
more granular scratchwork: https://git.evergreen-ils.org/?p=working/SIPServer.git;a=shortlog;h=refs/heads/collab/phasefx/sip-redaction-squashed

This is new functionality that allows you to add stanzas like these to the SIP configuration file for modifying SIP responses:

<filters>
    <!--
        Filters allow SIPServer to strip or modify specified fields inline from outgoing SIP messages. Currently, these
        rules apply to all message types and only work for variable-length fields, but the config layout leaves room for
        future enhancement.

        Examples:

        <field identifier="AE" replace_with="John Doe" />
        <field identifier="BE" remove="true" />
    -->
</filters>

Not yet pullrequesting until we're happy with the SIP test suite revitalization branch.

I removed the dependency on bug 1989478 and cherry-picked the commit into master and resolved a minor conflict. The test suite as a whole still doesn't pass, but 16filters.t does, assuming a concerto database by default, or by modifying SIPtest.pm as appropriate (which should be reconciled with oils_sip.xml anyway when testing).

So... pullrequested. :-)

Here's a sign-off for the SIP filters branch:

My tested consisted of manual tests, similar to how I tested the SIPMediator variant. Filters behaved as expected.

Merged to main. Thanks, Bill and Jason!
