tar,unzip: postpone creation of symlinks with "suspicious" targets
...
This mostly reverts commit bc9bbeb2b8
"libarchive: do not extract unsafe symlinks unless $EXTRACT_UNSAFE_SYMLINKS=1"
Users report that it is somewhat too restrictive. See
https://bugs.busybox.net/show_bug.cgi?id=8411
In particular, this interferes with unpacking of busybox-based
filesystems with links like "sbin/applet" -> "../bin/busybox".
The change is made smaller by deleting ARCHIVE_EXTRACT_QUIET flag -
it is unused since 2010, and removing conditionals on it
allows commonalizing some error message codes.

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

libarchive: add capability to unpack to mem.buffer

The performance and number of processes for a "depmod -a" with gzipped
modules was abysmal. This patch adds a code path without fork,
benefiting all users of xmalloc_open_zipped_read_close.
"modinfo radeon.ko.gz", a single-file reader, got 30% faster.
"depmod -a", which used to fork over 800 times, got 20% faster.
Heavily based on a patch by Lauri Kasanen <curaga@operamail.com>
