Add a "record type" field to "struct wtap_pkthdr"; currently, it can be
REC_TYPE_PACKET, for a record containing a packet, or
REC_TYPE_FILE_TYPE_SPECIFIC, for records containing file-type-specific
data.
Modify code that reads packets to be able to handle non-packet records,
even if that just means ignoring them.
Rename some routines to indicate that they handle more than just
packets.
We don't yet have any libwiretap code that supplies records other than
REC_TYPE_PACKET or that supporting writing records other than
REC_TYPE_PACKET, or any code to support plugins for handling
REC_TYPE_FILE_TYPE_SPECIFIC records; this is just the first step for bug
8590.

Lua can create a file reader/writer, to open new capture file
formats or write to new ones. To save local state, it can save
things in Lua itself; but since there can be multiple open files
at the same time (for example during a reload), the Lua script
won't know for which file and state its read/write functions are
being invoked for. To remedy this, and also provide a convenient
way to store such state, this commit adds the ability for a Lua
script to store a Lua table in the wtap/wtap_dumper's priv
data member, just like C-code-based reader/writers do.

The testsuite for Lua file reader/writer uses the acme_file.lua script to
generate a pcapng file from an Acme sipmsg.log file. It then compares the
tshark verbose output of this new pcapng file to a sip.pcapng file in
the test/captures directory that was previously made. Unfortunately, the
acme_file.lua script generates a timestamp based on local system timezone,
rather than UTC, so the testsuite fails if not run in the EST timezone where
the sip.pcapng file was originally made. This has now been fixed.
Also, trying to register new weak heuristic readers fails because the GArray
is terminated with a NULL-based row without Glib knowing about that. So this
commit changes it to let Glib handle the NULL-terminated row, so that appending
takes it into account automatically.

This enables a Lua script to implement a brand new capture file format reader/writer, so that for example one could write a script to read from vendor-specific "logs" of packets, and show them as normal packets in wireshark.
