   TESTrun: Cover gen_load_internal() better.
   The function implements five accessor groups, which relate to the
   following cases in gen_load_a():
   * OR_PACKET (radio[]),
   * OR_LINKHDR (link[]),
   * OR_LINKPL (ip[], arp[], rarp[], atalk[], decnet[], sca[], lat[],
     moprc[], mopdl[] and ip6[]),
   * OR_TRAN_IPV4 (sctp[], tcp[], udp[], icmp[], igmp[], igrp[], pim[],
     vrrp[] and carp[]), and
   * OR_TRAN_IPV6 (icmp6[]).
   
   From a loading offset calculation perspective, there are three DLT
   groups with:
   * a variable-length link-layer prefix *and* header (DLT_PRISM_HEADER,
     DLT_IEEE802_11_RADIO_AVS, DLT_IEEE802_11_RADIO and DLT_PPI),
   * a variable-length link-layer *or* header (DLT_IEEE802_11 and
     DLT_PFLOG), and
   * a constant-length link-layer header (everything else, but in the scope
     of this testing limit it to DLT_EN10MB, DLT_RAW, DLT_PPP,
     DLT_LINUX_SLL, DLT_LINUX_SLL2, DLT_DSA_TAG_BRCM and DLT_ARCNET_LINUX).
   
   This combinatorial space has a few irregularities: radio[] rejects all
   DLTs except three; DLT_PFLOG, DLT_RAW, DLT_PPP and DLT_ARCNET_LINUX do
   not support all accessors in the OR_LINKPL-like group; igrp[] uses one
   of two OS-dependent protocol numbers; vrrp[] and carp[] are effectively
   synonyms; DLT_PFLOG uses OS-specific AF numbers (two for AF_INET and
   seven for AF_INET6), and IPv4 transport currently generates an IPv6
   branch.
   
   Considering individual accessors and individual DLTs, the maximum number
   of permutations is 3 + 20 * 13 + 12 + 9 * 6 + 13 = 342.  Considering C
   code paths, not all permutations need to be tested, so keep the existing
   halfword and word blocks for link[] and replace all other index test
   blocks with 111 new test blocks.  Order the new blocks to match the
   order of cases in the C switch block.
   
   The new test blocks test every accessor above with at least one DLT in
   each supported DLT group above, as well as every DLT above with at least
   one supported (and at least one unsupported where applicable) accessor
   in each accessor group above.  Add three minimal tests to exercise the
   case of variable link-level prefix and header and VLAN/Geneve/VXLAN
   before TCP.
   
   Add filter apply tests for: radio[], link[], arp[], ip[], tcp[], icmp[],
   udp[], vrrp[], carp[], ip6[] and icmp6[].  carp.pcap is the first 5
   packets from Wireshark 10726-tcpdump-carp.pcap.  ieee802.11_exthdr.pcap
   is the last 10 packets from the tcpdump test file.

   Deduplicate code in gen_proto_abbrev_internal().
   Factor four helper functions out to translate from a proto qualifier to
   a protocol code point, and condense much of the switch block into six
   parametrised groups.

   Get IPv4 transport right in gen_load_internal().
   The function uses one invocation of gen_proto_abbrev_internal() to match
   the transport protocol of interest over IPv4, which includes matching of
   the link-level protocol as IPv4, or (for TCP, UDP, SCTP and PIM) also
   over IPv6, which includes matching of the link-level protocol as IPv6.
   It uses another invocation thereof to match strictly IPv4 as the
   link-level protocol.  The resulting filter program includes two
   consecutive tests for IPv4 if the DLT supports IPv4 and one always-false
   test for IPv6 (and the dependent unreachable branch) if the DLT supports
   IPv6.
   
   To fix this, match IPv4 only exactly once using proto_abbrev_internal(),
   then match the transport protocol of interest using gen_ip_proto().
   This produces filter programs without the unnecessary instructions, so
   update the tests.  Denote this pitfall in a comment, and a similar one
   in the Q_ICMPV6 case.
   
   While at it, make sure gen_and() does not get both of its arguments from
   a function call -- this seems to have been deterministic in this
   context, but it is better when the code is obviously deterministic.

   Layer gen_load_a() and gen_load_absoffsetrel() better.
   gen_load_absoffsetrel() needs to know whether the variable part of the
   absolute offset is present, but not how it has been generated.
   gen_load_a(), when the variable part comes from a different source
   (OR_TRAN_IPV4) or is definitely absent (OR_PACKET), does not need to
   duplicate what gen_load_absoffsetrel() does.
   
   In gen_load_absoffsetrel() validate the load size, take an optional
   variable part and a mandatory constant part as the arguments and focus
   on producing the load instruction(s).  In gen_load_a() focus on
   preparing the absolute offset components and use gen_load_absoffsetrel()
   to handle all cases.  Constify some arguments in both functions.

   Deduplicate code in gen_load_internal().
   Delegate the generation of side effect statements to a new function,
   gen_load_absoffsetarthrel(), and invoke it exactly once after the switch
   block has determined the variable and the constant parts of an absolute
   offset.  Merge protocol checks into the arithmetic expression only after
   the switch block has generated any.

   Factor gen_frelay_nlpid() out.
   Also define exactly the set of named NLPID constants this code needs.
