Improve mimeview

Old short option '-t' renamed to '-f' for consistency (-f stands for
--file in most other utilities).  Thus, 'mimevief -f my.types' reads
the file 'my.types'.

The '-t' option is reused as a short equivalent of the new
'--lint' option, which instructs the tool to check the syntax of the
mime.types file and exit, ignoring any surplus command line arguments.

Added support for priority and regex functions.

Improved debugging output.

* mimeview/mimetypes.l: Rewrite lexer in a cleaner way.
* mimeview/mimetypes.y: Rewrite parser.  Track locations.  Add line
information to nodes and rules.  Improve debugging
* mimeview/mimeview.c: Remove the debug configuration statement.  Using
debug { level } provides the same functionality.  Use mu_debug for debugging.
New option -t (--lint).  Rename the -t short option to -f.
* mimeview/mimeview.h: Define lexer and parser macros for location tracking.

* NEWS: Document changes to mimeview utility.
* doc/texinfo/programs.texi: Document changes to mimeview utility.

* lib/mailcap.c: Use standart mu_debug calls for debugging.
* lib/mailcap.h (display_stream_mailcap): Change last argument: take a
mu_debug_handle_t
* libmailutils/diag/debcat (app): New category.  Application-specific
debug
* mail/decode.c (display_submessage): Change invocation of
display_stream_mailcap.
* mail/mailvar.c: Setting "verbose" enables app.trace7, unsetting it
clears app.*
