Make plugins.c the source of truth for plugin names. Where plugins
reside and what they do are two different things, so split the plugin
directory and description into two separate elements.
CMake creates portable[1] builds on Windows and macOS. That is, the
build-time directory layout is the same as the installation directory
layout. Adjust various plugin paths macOS accordingly.
[1] You have to run osx-app.sh on macOS to prepare the application
bundle, but the goal is to create a directory/bundle that can be moved
or copied to a different system and run in the new location.

CentOS 6 ships with glib 2.28.8 which do not support
g_ptr_array_new_full (make-taps/make-dissectors) and need to link with

g_thread_new was only introduced with GLib 2.32 (not 2.31), so adjust
the check accordingly. Abort in case thread creation fails (as
documented). Properly initialize threads or it will abort on runtime
(this also requires linking epan with gthreads in CMake, autotools

Allow epan itself to be extended by plugins. Adds the following new plugin
interfaces:
void plugin_epan_init()
void plugin_epan_dissect_init(epan_dissect_t *)
void plugin_epan_dissect_cleanup(epan_dissect_t *)
void plugin_epan_cleanup()
void plugin_epan_register_all_protocols(register_cb, gointer) [OPTIONAL]
void plugin_epan_register_all_handoffs(register_cb, gointer) [OPTIONAL]
Any one of these can be an empty function but the first four must be
present.
The motivation for the change is a better way to implement a language binding
other than registering a fake protocol and stuffing everything into a single
dissector call (and maybe require an extra packet_info field) but I expect
there would be other interesting use cases.

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.

libwireshark now expects an epan_t to be created with a pointer to a
"packet provider" structure; that structure is opaque within
libwireshark, and a pointer to it is passed to the callbacks that
provide interface names, interface, descriptions, user comments, and
packet time stamps, and that set user comments. The code that calls
epan_new() is expected to provide those callbacks, and to define the
structure, which can be used by the providers. If none of the callbacks
need that extra information, the "packet provider" structure can be
null.
Have a "file" packet provider for all the programs that provide packets
from a file.

This patch introduces the frame.interface_description field.
While testing this new functionality it became obvious that we have
a non-optimal interaction between the existing cfile.c's
cap_file_get_interface_name(), the recently added frame.interface_name
field and this new frame.interface_description field.
The string returned from cap_file_get_interface_name() may in fact
come from one of three different sources: the idb's interface name
(if it exists) or the idb's interface description (if that exists)
or a default text of "unknown". The string ultimately becomes the
rame.interface_name whether or not the idb had an interface name
option to begin with. This behavior does not allow one to test for
the simple presence of frame.interface_name. The new peer function
cap_file_get_interface_description() added by this patch returns
NULL instead of "unknown" if the idb does not have an interface
description. Should cap_file_get_interface_name() be similarly
modified to return NULL if the idb does not have an interface name?
