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.

for type and length, and then endianess converted if necessary.
Outputs all blocks using the original endianess format so none of the

This sets the scope of the static build option to Wireshark support
libraries only.
Before the patch:
Static plugins don't work with CMake and autotools.
autotools static build is broken, and most likely will always be, as
building Wireshark all-static is difficult and time-consuming.
After the patch:
For CMake Wireshark will be built with static or shared libraries and
dynamic plugins. Everything just works. CMake apparently doesn't want
you building static and shared libraries at the same time.
For autotools Wireshark will be built with shared libraries by default.
--disable-shared and --enable-static options work as usual. Dlopened
plugins are not built if --disable-shared is given to configure (to
disable shared libraries). This is a limitations imposed by libtool.
Tested on Linux. This removes broken support for building plugins
statically.

the port types will be removed/updated and that changes the implicit values

Autotools has the very useful feature by design of allowing the user
to override the default build flags (you break it you keep it).
Apparently CMake applies COMPILE_OPTIONS target property after
CMAKE_{C,CXX}_FLAGS so that doesn't work here. Prepend our flags to those
variables instead to make it work then.
Specific target flag overrides can still be added with COMPILER_OPTIONS
(e.g: generated files with -Wno-warning) but this is less effective and
then we're back at the point where this overrides user flags. It's less
of a concern though.
