Delete obsolete /* ARGSUSED */ lint comments.

Add a 'batch' mode to mg via the '-b' command line option which will
initialise a pty, run the specified file of mg commands and then exit.

This is to facilitate mg fitting into the OpenBSD regress test
framework and be able to run via a cron job.

Put the hardcoded '\n' character which is found throughout mg into a
buffer specific variable. The diff should not produce any behavourial
changes in mg.

Do not define variables in def.h since this will lead to duplicate definitions
in every source file that includes def.h

More unifdef cleanup:
-UDIRED_XMAPS and -UFUND_XMAPS: you can't build mg the other way.
-DTIOCGWINSZ: you have this if you have term.h
Remove a #define TERMCAP which isn't being used.

Remove defines for NDIRED_XMAPS, NFUND_XMAPS, and IMAPEXT. They are all
defined to be 0 and are only ever used in addition. We don't need to add 0.
Simply lines that were using those defines.

Clean up the includes in mg.
This does the following:
Moves all POSIX headers from sysdef.h into the individual .c files so that
each file now only includes what it needs. All headers are properly sorted.
Moves the remainder of sysdef.h to other files (mostly def.h) and deletes
sysdef.h now that it's no longer contains anything.
Tweak a comment that references sysdef.h so that it no longer does that.

It is impossible to build mg without both -DFKEYS and -DXKEYS. So let's
