Remove SVR2 support
SVR2 was obsolete by 1986 and is no longer supported by anybody, and its
code was getting in the way of use of this module by Emacs, which has
its own 'read' function anyway.
* src/filemanager/mountlist.c: remove SVR2-specific code.
* m4.include/fsusage.m4: do not test for sys/filsys.h or set
STAT_READ_FILSYS.

See gnulib a512e041120e9012e69afa2f5c3adc196ec4999a:
glibc 2.25 is deprecating the namespace pollution of <sys/types.h>
injecting major(), minor(), and makedev() into the compilation
environment, with a warning that insists that users include
<sys/sysmacros.h> instead. However, because the expansion of
AC_HEADER_MAJOR didn't bother checking sys/sysmacros.h until after
probing whether sys/types.h pollutes the namespace, it was not defining
MAJOR_IN_SYSMACROS, with the result that code compiled with -Werror
chokes on the deprecation warnings because it was not including
sysmacros.h.

When ncurses library is built with --with-termlib option
the resulting installation contains two libraries:
/lib64/libncurses.so.6
/lib64/libncursesw.so.6
/lib64/libtinfo.so.6
/lib64/libtinfow.so.6
As a result mc build fails as:
$ ./configure --with-screen=ncurses
$ make
CCLD mc
/usr/lib/gcc/x86_64-pc-linux-gnu/5.4.0/../../../../x86_64-pc-linux-gnu/bin/ld:

When using slang, 'configure' prints blank in the "Screen library" name:
...
File system: Midnight Commander Virtual Filesystem
cpio, extfs, fish, ftp, sfs, sftp, smb, tar
Screen library:
Mouse support: gpm and xterm
X11 events support: yes
...
This occurs when slang is found using pkg-config (as opposed to explicit path
search). The patch fixes this by moving the 'screen_msg' assignment one level
up, to the controlling function (mc_WITH_SLANG) so that it's effective for
however method the library was found.
The problem was mentioned on our mailing list:

On systems where 'mode_t' is smaller than 'int', doing 'va_arg (ap, mode_t)' is
wrong because of C's "default argument promotions". GCC 4 creates crashing code
in this case.
The "va_arg" page of Gnulib's manual describes the problem and a simple solution:
https://www.gnu.org/software/gnulib/manual/html_node/va_005farg.html
However, since that solution reportedly (see thread at next link) still causes
GCC to print warnings (for no good reason; perhaps this was fixed in newer
GCCs), we pick a solution that defines a PROMOTED_MODE_T at the configuration
stage:
https://lists.gnu.org/archive/html/bug-gnulib/2009-05/msg00231.html
(We take our 'mode_t.m4' from the most recent Gnulib source.)
(If any of the URLs above no longer works, simply search the web for the
mentioned words.)
Macros get from other projects keep their original names:
gl_FSTYPENAME, AX_PATH_LIB_PCRE, etc.
Macros initially writtem for MC have original names with prefix mc_:
mc_VERSION, mc_CHECK_GLIB, etc
Macros get from other projects and modified for MC keep their
original names with prefix mc_:
mc_cu_PREREQ_STAT_PROG, mc_AC_GET_FS_INFO.

Sync with gnulib 3fb6e360363744462ce15c381f0b116c6fc4ce82.
src/filemanager/mountlist.c: remove dependency on libmount.
Parse /proc/self/mountinfo directly, rather than depending on libmount,
which has many dependencies due to its dependence on libselinux, as
detailed at:
http://lists.gnu.org/archive/html/bug-gnulib/2015-01/msg00063.html.
Note we restrict this to __linux__ as that's probably where this
interface will remain. If ever porting, it would be best to first pull
the makedev() wrapper from coreutils to a gnulib module.

mountlist: use /proc/self/mountinfo when available
Use libmount to propagate device IDs provided by Linux in
/proc/self/mountinfo. This will give more accurate output when using df
in chroot'ed environments as the device IDs are not determined by stat()
which may be inaccurate within the chroot.
