Added single file filesystem (sfs)
Added vfs_flags so library users can disable selected filesystems
Minor shuffling of functions so garbage collection works for library
* utilunix.c, util.h (errno_dir_not_empty): deleted

* file.c (check_dir_is_empty): New function which takes a path and
returns -1 on error, 1 if there are no entries besides "." and
".." in the directory path points to, 0 else. This function
actually opens and reads the directory and doesn't do tricks we
used to do with rmdir.
* file.c (erase_dir, erase_dir_iff_empty): Use check_dir_is_empty
to detect non empty directories. The old code tried to remove the
directory and decided on errno whether the failure of rmdir was
caused by a non empty directory or whether there was a different
error.
Unfortunatly not every filesystem sets errno to EDIRNOTEMPTY if
you try to delete a non empty directory. Namely the linux user
space nfs server sets errno to EIO, Suns nfs server sets it to
EEXIST and the AIX nfs server sets it to ??? (Steve reported
problems on AIX so I guess AIX sets errno to a value we currently
don't check).
* src/complete.c: obsolete hack for OS/2 and NT removed.
Completion works for NT now (not very good)
* src/main.c: HOME variable is respected by NT and OS/2
versions. If it is missing, we use LIBDIR on OS2_NT and "/"
on Unix.
* src/key.h: SHIFT_PRESSED is set to 0x0010 on NT. This value
doesn't conflict with definitions for ALT and CTRL, but it is
SDK-compatible.
* vfs/vfs.h: Minor changes for OS/2. EMX defines mkdir with
2 arguments
* vfs/tcputil,c, vfs/utilvfs.c: signal.h was includes twice.
* vfs/Makefile.in: undelfs.h is not used and should disapper
* slang/slos2tty.c: new file, copied from SLang-0.99.38,
needed for OS/2 port
* slang/Makefile.in: added slos2tty.c
* vfs/extfs/README: annoying spell errors corrected
* src/main.c: --termcap disabled for OS2_NT because it doesn't
(and cannot) work. ARCH_FLAGS is not needed anymore.
* src/text.c: most includes removed. Added a warning is someone
compiles this file with HAVE_X. Improved color scheme for
consoles with 16 background colors (e.g. OS/2). Hack for OS/2
removed.
* src/util.c, src/util.h: STRCOMP and MC_ARCH_FLAGS are moved
to util.h. It may be useful to use them for filenames' completion
on OS2_NT
