net/bind916: update to 9.16.31

9.6.31 (2022-07-20)

5917. [bug] Update ifconfig.sh script as is miscomputed interface
identifiers when destroying interfaces. [GL #3061]

5915. [bug] Detect missing closing brace (}) and computational
overflows in $GENERATE directives. [GL #3429]

5913. [bug] Fix a race between resolver query timeout and
validation in resolver.c:validated(). Remove
resolver.c:maybe_destroy() as it is no loger needed.
[GL #3398]

5909. [bug] The server-side destination port was missing from dnstap
captures of client traffic. [GL #3309]

5905. [bug] When the TCP connection would be closed/reset between
the connect/accept and the read, the uv_read_start()
return value would be unexpected and cause an assertion
failure. [GL #3400]

5903. [bug] When named checks that the OPCODE in a response matches
that of the request, if there is a mismatch named logs
an error.  Some of those error messages incorrectly
used RCODE instead of OPCODE to lookup the nemonic.
This has been corrected. [GL !6420]
