Add a dissector for reading Sysdig event blocks. It only handles plain
events but it's usable for reading trace files on hand here.
Use a script to generate various parts of the dissector. As an experiment,
update parts in-place instead of using a template.
Ultimately there should probably be a top-level "Syscall" or "Event"
dissector alongside the "Frame" dissector, which could then call this.
You could then directly compare an executable's system calls alongside
its network traffic.
For now leverage the pcapng_block dissector and keep everything under
"Frame".
Next steps:
- Items listed at the top of packet-sysdig-event.c.

*Especially* don't stuff the amount of remaining data in a block into an
int that will then be passed to file_skip() as an amount to skip ahead,
as a Really Large Value will turn into a negative value and produce
various forms of bizarre and tricky-to-debug behavior.

Make pcapng decode options in an NRB during read, and store the comment
option, and write it back out as well. Also make it handle plugin handlers
for unknown options in received NRB(s).

For example, this can be used for pcap-ng options not mapped to
file-type-independent metadata values.

We rename "file format" plugins to "libwiretap" plugins, as they can
register as read handlers for a new file type, read/write handlers for a
pcap-ng block type (or both).
To register as a pcap-ng block type handler, in the
register_wtap_module() routine of your plugin, call
register_pcapng_block_type_handler() with the pcap-ng block type and
pointers to your routines to read and write those blocks. Those
routines should read and write REC_TYPE_FILE_TYPE_SPECIFIC records, with
the block type in the pseudo-header for the record in the struct
wtap_pkthdr structure, with time stamps stored in that structure, and
with a blob of data for the rest of the record.
This is for bug 8590.
