c3045edec2 xz: fix incorrect XZ_BUF_ERROR 
xz_dec_run() could incorrectly return XZ_BUF_ERROR if
all of the following was true:

  - The caller knows how many bytes of output to expect
    and only provides that much output space.

  - When the last output bytes are decoded, the
    caller-provided input buffer ends right before
    the LZMA2 end of payload marker. So LZMA2 won't
    provide more output anymore, but it won't know it
    yet and thus won't return XZ_STREAM_END yet.

  - A BCJ filter is in use and it hasn't left any
    unfiltered bytes in the temp buffer. This can happen
    with any BCJ filter, but in practice it's more likely
    with filters other than the x86 BCJ.

This fixes <https://bugzilla.redhat.com/show_bug.cgi?id=735408>
where Squashfs thinks that a valid file system is corrupt.
Thanks to Jindrich Novy for telling me that such a bug report
exists, Phillip Lougher for providing excellent debug info,
and other people on #fedora-ppc.

This also fixes a similar bug in single-call mode where the
uncompressed size of a XZ Block using BCJ + LZMA2 was 0 bytes
and caller provided no output space. Many empty .xz files
don't contain any Blocks and thus don't trigger this bug.

This also tweaks a closely related detail: xz_dec_bcj_run()
could call xz_dec_lzma2_run() to decode into temp buffer when
it was known to be useless. This was harmless although it
wasted a minuscule number of CPU cycles.

a1ae2b75a7 xz: fix decoding of LZMA2 streams having no uncompressed data. 
No .xz encoder creates files with empty LZMA2 streams,
but such files would still be valid and decompressors
must accept them.

Note that empty .xz files are a different thing than
empty LZMA2 streams. This bug didn't affect typical .xz
files that had no uncompressed data.

b76f18d331 Improve unzip's handling of stream ZIP files 
Search harder for the ZIP magic numbers at the end of a file by checking
16 KiB from the end instead of just 1 KiB.  ZIP files with long comments
(such as certain cryptographically signed files) or those sitting in a
wrapper could have more than 1 KiB of data after the magic numbers, so
they couldn't be read.

d43d628f8b tar: revert part of last change. -39 bytes

f94c9bf288 tar: fix bug 673 (misdetection of repeated dir as hardlink). +92 bytes 
While at it, remove many superfluous ops on unpack:
mkdir("."), lots of umask() calls. Can remove more
by caching username->uid.
