Add a "report a warning message" routine to the "report_err" code in
libwsutil, and rename files and routines appropriately, as they don't
only handle errors any more.
Have a routine read_enabled_and_disabled_protos() that reads all the
files that enable or disable protocols or heuristic dissectors, enables
and disables them based on the contents of those files, and reports
errors itself (as warnings) using the new "report a warning message"
routine. Fix that error reporting to report separately on the disabled
protocols, enabled protocols, and heuristic dissectors files.
Have a routine to set up the enabled and disabled protocols and
heuristic dissectors from the command-line arguments, so it's done the
same way in all programs.
If we try to enable or disable an unknown heuristic dissector via a
command-line argument, report an error.
Update a bunch of comments.
Update the name of disabled_protos_cleanup(), as it cleans up
information for disabled *and* enabled protocols and for heuristic
dissectors.
Support the command-line flags to enable and disable protocols and
heuristic dissectors in tfshark.

Motivation for this change is that many dissectors depend on Libgcrypt

Furthermore, wsutil has crypto code that can be replaced by Libgcrypt.

Make the init_progfile_dir() call unconditionally, even if plugins
aren't supported, as that doesn't necessarily mean nobody uses the
directory containing the executable.
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).
Have the plugin scanner just fail silently if we weren't able to get the
plugin directory path, so we don't have to worry about calling it if
init_progfile_dir() fails.
