bca5c556c4 udhcpc: use readlink rather than realpath
The realpath utility requires all paths exist when canonicalizing

not exist initially.  Use `readlink -f` so that we follow all
symlinks that are available.

Because when -x is used (exact match), then we cannot compile the
regular expression with REG_NOSUB. The manual page regcomp(3) states
in section "Byte offsets":

    Unless REG_NOSUB was set for the compilation of the pattern
    buffer, it is possible to obtain substring match addressing
    information.

The problem was detected on an ARM system with glibc 2.16.

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.

5bce135e36 mdev: improve $SEQ handling; improve debug logging
Sequential run of concurrent mdev's was too simplistic:
they waited for /dev/mdev.seq to match. This could sometimes
cause cumulative loss of time on the order of a second.

Added SIGCHLD signaling from exiting mdev to all other mdev's.
Added debugging required to see that code actually works as intended.

Example of /dev/mdev.log (with "woken up" elevated from dbg lvl 3 to 2):
