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.

Simplify "configure: checking ..." messages.
* m4.include/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Update copyright
years. Use AC_MSG_CHECKING instead of AC_MSG_NOTICE.

Avoid needless check on GNU/Linux.
* m4.include/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Omit STAT_STATFS3_OSF1 check
on GNU/Linux systems, since it can't possibly work.

fs usage: fix block size returned on older Linux 2.6.
* src/filemanager/mountlist.c: Fall back to (struct statfs).f_frsize
which is available since Linux 2.6.
* m4.include/fsusage.m4 (STAT_STATFS2_FRSIZE): Always define
when the member is available so it can be used as a fallback.

Sync with gnulib c25bdbae48977a527dff69150f59fb0746d31b51:
fs usage: check for GNU/Linux statvfs problem dynamically.
* src/filemanager/mountlist.c [STAT_STATVFS && __linux__ && (__GLIBC__||__UCLIBC__)]:
Define STAT_STATFS2_BSIZE too, since in this case the code now
checks dynamically whether statvfs is reliable, falling back on
Linux-style statfs otherwise.
(statvfs_works): New function, for dynamically testing statvfs.
(get_fs_usage) [STAT_STATVFS]: Use it.
* src/filemanager/filegui.c (filegui__check_attrs_on_fs): apply the same
statvfs_works function.
* m4.include/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Remove static check for
statvfs on GNU/Linux hosts, since it's now done dynamically.
