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.

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.

Make mktemp more compatible with coreutils.
- add "--tmpdir" option
- add long variants for "d,q,u" options
Note: Upstream ca-certificate update script started using this option.

range_start was staying -1, and comparison meant to detect
"is it the first sendfile that failed, or not the first?"

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)
...
mount("/dev/sr0", "/mnt/sr0", 0x412862, MS_RDONLY|MS_REMOUNT|MS_SILENT|MS_RELATIME, "nojoliet,check=s,map=n,blocksize"...) = 0
Clearly, not what was intended!

procps-ng 3.3.15 does not do this.

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.

Add the --post-file option to send form data from a file. As with
--post-data it's up to the user to ensure that the data is encoded
as appropriate: all wget does is stuff the provided data into
the request.
The --post-data and --post-file options are mutually exclusive and
only one instance of either may be given.
Additionally:
- update the usage message to include missing details of the --post-data
and --header options;
- free POST data if FEATURE_CLEAN_UP is enabled.
