e7b424d267 Make the progress indicator smooth in threaded mode.
This adds lzma_get_progress() to liblzma and takes advantage
of it in xz.

lzma_get_progress() collects progress information from
the thread-specific structures so that fairly accurate
progress information is available to applications. Adding
a new function seemed to be a better way than making the
information directly available in lzma_stream (like total_in
and total_out are) because collecting the information requires
locking mutexes. It's waste of time to do it more often than
the up to date information is actually needed by an application.

db5c1817fa xzless: Make "less -V" parsing more robust
In v4.999.9beta~30 (xzless: Support compressed standard input,
2009-08-09), xzless learned to parse ‘less -V’ output to figure out
whether less is new enough to handle $LESSOPEN settings starting
with “|-”.  That worked well for a while, but the version string from
‘less’ versions 448 (June, 2012) is misparsed, producing a warning:

	$ xzless /tmp/test.xz; echo $?
	/usr/bin/xzless: line 49: test: 456 (GNU regular expressions): \
	integer expression expected
	0

More precisely, modern ‘less’ lists the regexp implementation along
with its version number, and xzless passes the entire version number
with attached parenthetical phrase as a number to "test $a -gt $b",
producing the above confusing message.

	$ less-444 -V | head -1
	less 444
	$ less -V | head -1
	less 456 (no regular expressions)

So relax the pattern matched --- instead of expecting "less <number>",
look for a line of the form "less <number>[ (extra parenthetical)]".
While at it, improve the behavior when no matching line is found ---
instead of producing a cryptic message, we can fall back on a LESSPIPE
setting that is supported by all versions of ‘less’.

The implementation uses "awk" for simplicity.  Hopefully that’s
portable enough.

3778db1be5 liblzma: Make the use of lzma_allocator const-correct.
There is a tiny risk of causing breakage: If an application
assigns lzma_stream.allocator to a non-const pointer, such
code won't compile anymore. I don't know why anyone would do
such a thing though, so in practice this shouldn't cause trouble.

Thanks to Jan Kratochvil for the patch.

d8db706acb liblzma: Fix possibility of incorrect LZMA_BUF_ERROR.
lzma_code() could incorrectly return LZMA_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 LZMA_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.

Another situation where the bug can be triggered happens
if the uncompressed size is zero bytes and no output space
is provided. In this case the decompression can fail even
if the whole input file is given to lzma_code().

A similar bug was fixed in XZ Embedded on 2011-09-19.
