Put different types of plugins (libwiretap, libwireshark) in different
subdirectories, give libwiretap and libwireshark init routines that
load the plugins, and have them scan the appropriate subdirectories
so that we don't even *try* to, for example, load libwireshark plugins
in programs that only use libwiretap.
Compiled plugins are stored in subfolders of the plugin folders, with
the subfolder name being the Wireshark minor version number (X.Y). There is
another hierarchical level for each Wireshark library (libwireshark, libwscodecs
and libwiretap).
The folder names are respectively plugins/X.Y/{epan,codecs,wiretap}.
Currently we only distribute "epan" (libwireshark) plugins.

Support per-packet comments in ERF_TYPE_META through a new Anchor ID
extension header with per-Host unique 48-bit Anchor ID which links an
ERF_TYPE_META record with a packet record. There may be more than one
Anchor ID associated with a packet, where they are grouped by Host ID
extension header in the extension header list. Like other ERF_TYPE_META
existing comments should not be overwritten and instead a new record
generated. See erf_write_anchor_meta_update_phdr() for detailed comments
on the extension header stack required.
As Wireshark only supports one comment currently, use the one one with
the latest metadata generation time (gen_time). Do this for capture
comment too.
Write various wtap metadata in periodic per-second ERF_TYPE_META records
if non-WTAP_ENCAP_ERF or we have an updated capture comment.
Refactor erf_dump to create fake ERF header first then follow common
pseudoheadr and payload write code rather than two separate code paths.

opt_comment has unsaved changes by the user.
Add needs_reload to wtap_dumper which forces a full reload of the file

Report the error the same way in all programs, and free the error string
after we're finished with it.
Make the error - and the comment before the code - reflect what
init_progfile_dir() is actually doing (the goal is to get the full
pathname of the directory *containing* the executable; that's generally
done by getting the pathname of the executable and stripping off the
name of the executable, but that's won't necessarily always be the
case). Also note for TShark that we won't be able to capture traffic,
just as we do for Wireshark (if we don't have the pathname of the
program file, we don't have a pathname to use to find dumpcap).

Add additional --novlan flag for removing vlan tag info before checking for duplicates.
When capturing with -i any you could see packets more than once and some drivers include vlan info.
With the --novlan the vlan info is removed from the packet so that checksum duplication detection can be used,
if the rest of the packets are the same.

The "-Wwrite-strings" flag produces nuisance warnings. These warnings are
not useful, they're impossible to fix in a sane way and therefore are being
handled with casts of static strings to (char *).
This just moves the warning to [-Wcast-qual] and a compiler pragma is
in turn required (and used) to squelch that warning.
Remove the Wwrite-strings warning. Let that responsibility fall on the
programmer (as is done by casting).
