test-dns-packet: add framework to read and dump packets

Packets are stored in a simple format:
<size> <packet-wire-format> <size> <packet-wire-format> ...

Packets for some example domains are dumped, to test rr code for various
record types. Currently:
A
AAAA
CAA
DNSKEY
LOC
MX
NS
NSEC
OPENPGPKEY
SOA
SPF
TXT

The hashing code is executed, but results are not checked.

Also build other tests in src/resolve only with --enable-resolve.
