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.

Thanks to Olivier Delhomme for pointing out that this
was still missing.

The decoder bug was fixed in 5.0.2 instead of 5.0.3.

88ccf47205 xz: Add incomplete support for --block-list. 
It's broken with threads and when also --block-size is used.

ec92110572 xz: Document the "summary" lines of --robot -lvv. 
This documents only the columns that are in v5.0.
The new columns added in the master branch aren't
necessarily stable yet.

27d24eb0a9 xz: Fix output of verbose --robot --list modes. 
It printed the filename in "filename (x/y)" format
which it obviously shouldn't do in robot mode.

c029744506 xz: Fix error handling in xz -lvv. 
It could do an invalid free() and read past the end
of the uninitialized filters array.

4161d76349 xz: Translate also the string used to print the program name. 
French needs a space before a colon, e.g. "xz : foo error".

7a480e4859 xz: Fix input file position when --single-stream is used. 
Now the following works as you would expect:

    echo foo | xz > foo.xz
    echo bar | xz >> foo.xz
    ( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz

Note that it doesn't work if the input is not seekable
or if there is Stream Padding between the concatenated
.xz Streams.

9a4377be0d Put the unstable APIs behind #ifdef LZMA_UNSTABLE. 
This way people hopefully won't complain if these APIs
change and break code that used an older API.

3e321a3acd Remove doubled words from documentation and comments. 
Spot candidates by running these commands:
  git ls-files |xargs perl -0777 -n \
    -e 'while (/\b(then?|[iao]n|i[fst]|but|f?or|at|and|[dt]o)\s+\1\b/gims)' \
    -e '{$n=($` =~ tr/\n/\n/ + 1); ($v=$&)=~s/\n/\\n/g; print "$ARGV:$n:$v\n"}'

Thanks to Jim Meyering for the original patch.

ebd54dbd6e xz/DOS: Add experimental 8.3 filename support. 
This is incompatible with the 8.3 support patch made by
Juan Manuel Guerrero. I think this one is nicer, but
I need to get feedback from DOS users before saying
that this is the final version of 8.3 filename support.

cd4fe97852 xz/DOS: Be more careful with the destination file. 
Try to avoid overwriting the source file if --force is
used and the generated destination filename refers to
the source file. This can happen with 8.3 filenames where
extra characters are ignored.

If the generated output file refers to a special file
like "con" or "prn", refuse to write to it even if --force
is used.

335fe260a8 xz: Minor internal changes to handling of --threads. 
Now it always defaults to one thread. Maybe this
will change again if a threading method is added
that doesn't affect memory usage.

8930c7ae3f xz: Check if the file already has custom suffix when compressing. 
Now "xz -S .test foo.test" refuses to compress the
file because it already has the suffix .test. The man
page had it documented this way already.

03ebd1bbb3 xz: Fix --force on setuid/setgid/sticky and multi-hardlink files. 
xz didn't compress setuid/setgid/sticky files and files
with multiple hard links even with --force. This bug was
introduced in 23ac2c44c3.

Thanks to Charles Wilson.

f0fa880d24 xz: Avoid raise() also on OpenVMS. 
This is similar to DOS/DJGPP that killing the program
with a signal will print a backtrace or a similar message.

ac462b1c47 xz: Avoid SA_RESTART for portability reasons. 
SA_RESTART is not as portable as I had hoped. It's missing
at least from OpenVMS, QNX, and DJGPP). Luckily we can do
fine without SA_RESTART.

ef364d3abc OS/2 and DOS: Be less verbose on signals. 
Calling raise() to kill xz when user has pressed C-c
is a bit verbose on OS/2 and DOS/DJGPP. Instead of
calling raise(), set only the exit status to 1.
