Remove most of the built-in file types from the table in
wiretap/file_access.c and, instead, have the file types register
themselves, using wtap_register_file_type_subtypes().
This reduces the source code changes needed to add a new file type from
three (add the handler, add the file type to the table in file_access.c,
add a #define for the file type in wiretap/wtap.h) to one (add the
handler). (It also requires adding the handler's source file to
wiretap/CMakeLists.txt, but that's required in both cases.)
A few remain because the WTAP_FILE_TYPE_SUBTYPE_ #define is used
elsewhere; that needs to be fixed.
Fix the wiretap/CMakefile.txt file to scan k12text.l, as that now
contains a registration routine. In the process, avoid scanning files
that don't implement a file type and won't ever have a registration
routine.
Add a Lua routine to fetch the total number of file types; we use that
in some code to construct the wtap_filetypes table, which we need to do
in order to continue to have all the values that used to come from the
WTAP_FILE_TYPE_SUBTYPE_ types.
While we're at it, add modelines to a file that lacked them.
That makes them work as input to a mergecap that writes pcapng files.
File types that don't have a single per-file encapsulation type need
more work, with multiple fake IDBs, one for each packet encapsulation
type seen in the file, unless we can generate real IDBs.

That makes it - and the routines that implement it - work more like the
seek-read routine.
