* src/stat.c (HAVE_STRUCT_STATXFS_F_FSID___VAL): Define. This
macro was being used without being defined.
(SB_F_NAMEMAX): Remove cast.
(f_fsid) [BeOS]: Likewise.
(OUT_NAMEMAX): Renamed from NAMEMAX_FORMAT, with a new meaning.
All uses changed.
(out_string, out_int, out_uint, out_uint_o, out_uint_x): New
functions.
(xstrcat): Remove. All uses changed to use the above functions.
(print_statfs, print_stat): 2nd arg is now the prefix len, not the
buffer len. All uses changed. Output '?', not '*', for unknown
data or errors. Do not assume signed values can be interchanged
with unsigned when printing.
(print_statfs): For %i, print the fsid as a single int, not as a
pair.
(print_it): Quote invalid format better.
(STRUCT_STATVFS, statfs, f_fsid, f_blocks, f_bfree) [BeOS]:
(f_bavail, f_bsize, STATFS_FRSIZE, f_files, f_ffree) [BeOS]:
(STATXFS_FILE_SYSTEM_TYPE_MEMBER_NAME) [BeOS]: Define.
