836b79211d cpio: add support for --renumber-inodes like GNU cpio
The --renumber-inodes option renumbers the inodes starting from 1,
so that the sequence of inodes is always stable.  This helps with
reproducibility.

8aa5585ff4 cpio: add support for --ignore-devno like GNU cpio
The --ignore-devno option is used to set device numbers to (0, 0).
This can be useful in verifying whether a CPIO archive is reproducible.

aaf3d5ba74 shell: tweak --help
Even though formally it is -s [ARGS], "sh -s" without ARGS
is the same as just "sh". And we are already over 80 chars wide
for ash --help, so make it shorter.

21e8dbfd9d ash.c: speedup ${s:} substring (no quotes)
This trivial patch makes ${s:...} at least as fast as ${s#??..}
in simple tests. It's probably faster for longer substrings,
but then one wouldn't use ${s#"1024???s"} anyway -
one would switch away from sh.

94eb1c4dc6 libbb: better coreutils compatibility for realpath
Add some tests which coreutils realpath pass but BusyBox realpath
fails (bar one).  Adjust xmalloc_realpath_coreutils() so the tests
pass:

- Expand symbolic links before testing whether the last path component
  exists.

- When the link target is a relative path canonicalize it by passing
  it through xmalloc_realpath_coreutils() as already happens for
  absolute paths.

- Ignore trailing slashes when finding the last path component and
  correctly handle the case where the only slash is at the start of
  the path.  This requires ignoring superfluous leading slashes.

- Undo all changes to the path so error messages from the caller show
  the original filename.

The reported case was an attempt to remount,rw a CD-ROM:

  mount -o remount,rw /mnt/sr0

which "succeeded" by falling back to RO:

  mount("/dev/sr0", "/mnt/sr0", 0x412862, MS_REMOUNT|MS_SILENT|MS_RELATIME, "nojoliet,check=s,map=n,blocksize"...) = -1 EROFS (Read-only file system)

421c8767ba find: Unify time comparisons
Split the common part into a function, to be reused.

The tail call is optimized, meaning now mmin/mtime just prepare arguments
and jump into the common code, thus near zero overhead.

This reduces code size slightly, e.g. on x86_64:
   text    data     bss     dec     hex filename
   4806       0       0    4806    12c6 findutils/find.o.orig
   4782       0       0    4782    12ae findutils/find.o

Of course, the savings are even greater when implementing atime/ctime
variants.
