baa41c7855 ash: make ${v:N:M} more robust for very large M by clamping to MIN/MAX_INT 
Before this patch, "${v:2:0x100000001}" = "${v:2:1}",
and similarly, constructs like "${v:2:9999999999}" may give wrong result
due to int overflows.

4261341281 umount: ignore -c 
"-c, --no-canonicalize: Do not canonicalize paths."

As busybox doesn't canonicalize paths in the first place it is safe to ignore
this option.

return a non-zero exit code instead:

c6f213ade4 unzip: fix content listing and filtering when -j is used 
Original Info-ZIP's unzip uses unstripped filenames
while doing content listing and filtering, i.e.
 - in content listing mode -j is ignored completely
 - filtering is applied to non-stripped names, -j
   takes effect first while extracting the files

997ad2c64a strips path
components a little bit too early resulting in behavior
deviations.

Fix it by doing stripping after listing/filtering.

p.s. Info-ZIP's unzip behavior is the same as
     that of tar in --strip-components=NUM mode

6bcc2c0f6c grep: skip grepping symlinks to directories 
When grep is passed -r, recursive_action will treat any symlinks to
directories not in the root as normal files, since it lstat's them and
is therefore told they are not directories. However, file_action_grep
will still try to fopen and read from them to see whether they match,
which varies in behaviour across platforms. Linux will give EISDIR and
thus grep will not find any matching lines, but FreeBSD will give the
raw contents of the directory itself, which may match the given pattern.
Also, if grep is passed -c, it will even print a count for these
symlinks, even on Linux.

Since this recursive_action behaviour is required for the correct
functioning of other applets, such as tar, grep should handle this
special case and skip any such symlinks.
