*5.9.4*:

    IMPORTANT: SNMP over TLS and/or DTLS are not functioning properly
    in this release with various versions of OpenSSL and will be fixed
    in a future release.

    libsnmp:
      - Remove the SNMP_SWIPE_MEM() macro Remove this macro since it is not
	used in the Net-SNMP code base.
      - DISPLAY-HINT fixes
      - Miscellanious improvements to the transports
      - Handle multiple oldEngineID configuration lines
      - fixes for DNS names longer than 63 characters

    agent:
      - Added a ignoremount configuration option for the HOST-MIB
      - disallow SETs with a NULL varbind
      - fix the --enable-minimalist build

    apps:
      - snmpset: allow SET with NULL varbind for testing
      - snmptrapd: improved MySQL logging code

    general:
      - configure: Remove -Wno-deprecated as it is no longer needed
      - miscellanious ther bug fixes, build fixes and cleanups

Log message:
*/builtin.mk: Use ${_CROSS_DESTDIR:U} for build-time file checks.

These are questions about the target system, whose files at
build-time are all relative to ${_CROSS_DESTDIR} if it is defined,
i.e., if USE_CROSS_COMPILE is set to yes.

No change to native builds because ${_CROSS_DESTDIR:U} is empty in
them.  (Possible minor change by adding :Q to ${H_FOO} in command
lines, but if this makes a difference it likely fixes problems.)

Log message:
*: bump for openssl 3

Log message:
handle merged inpcb code since 9.99.104:
  http://mail-index.netbsd.org/source-changes/2022/10/28/msg141800.html

this is part 2 of fixes for net-snmp, and should work now (though i'm not
sure how to test properly, but it builds on both pre-/post- merge.)

Log message:
net-snmp: NetBSD >= 9.99.104 build fixes (part one)

Address fallout from struct inpcb changes in NetBSD 9.99.104, as
impacts ipv6.c, specifically. Note this is compile-tested only (on
9.99.108 and 9.3_STABLE), I don't use this package (nor any of its
dependants) and haven't tested the functionality.

(At least tcpTable.c and udpTable.c also need adjustments. I don't have
the time or patience to deal with them at the moment, I'm so checking
in what I've adjusted so far.)

(The upstream code in ipv6.c uses two inconsistent approaches to handle
differences in NetBSD versions. I opted for the more explicit code
blocks everywhere, to avoid confusion. I didn't bother using the new
macros added in 9.99.104 to fetch specific struct members, as they
don't cover much of what's needed here anyway, and would arguably just
make things look even more ugly.)
