Lasse Collin 3a0c5378ab Docs: Add new example programs.
These have more comments than the old examples and
human-readable error messages. More tutorial-like examples
are needed but these are a start.

Lasse Collin 1bd2c2c553 Docs: Move xz_pipe_comp.c and xz_pipe_decomp.c to doc/examples_old.
It is good to keep these around to so that if someone has
copied the decompressor bug from xz_pipe_decomp.c he has
an example how to easily fix it.

Lasse Collin 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.

This documents only the columns that are in v5.0.
The new columns added in the master branch aren't
necessarily stable yet.

It printed the filename in "filename (x/y)" format
which it obviously shouldn't do in robot mode.

Lasse Collin cff070aba6 Fix exit status of xzgrep when grepping binary files.
When grepping binary files, grep may exit before it has
read all the input. In this case, gzip -q returns 2 (eating
SIGPIPE), but xz and bzip2 show SIGPIPE as the exit status
(e.g. 141). This causes wrong exit status when grepping
xz- or bzip2-compressed binary files.

The fix checks for the special exit status that indicates SIGPIPE.
It uses kill -l which should be supported everywhere since it
is in both SUSv2 (1997) and POSIX.1-2008.

Thanks to James Buren for the bug report.

Lasse Collin e9ed88126e Run the scripts with the correct shell in test_scripts.sh.
The scripts are now made executable in the build tree.
This way the scripts can be run like programs in
test_scripts.sh. Previously test_scripts.sh always
used sh but it's not correct if @POSIX_SHELL@ is set
to something else by configure.

Thanks to Jonathan Nieder for the patch.

Lasse Collin 1c673e5681 Fix exit status of "xzdiff foo.xz bar.xz".
xzdiff was clobbering the exit status from diff in a case
statement used to analyze the exit statuses from "xz" when
its operands were two compressed files. Save and restore
diff's exit status to fix this.

The bug is inherited from zdiff in GNU gzip and was fixed
there on 2009-10-09.

Thanks to Jonathan Nieder for the patch and
to Peter Pallinger for reporting the bug.

Lasse Collin bd35d903a0 liblzma: Use symbol versioning.
Symbol versioning is enabled by default on GNU/Linux,
other GNU-based systems, and FreeBSD.

I'm not sure how stable this is, so it may need
backward-incompatible changes before the next release.

The idea is that alpha and beta symbols are considered
unstable and require recompiling the applications that
use those symbols. Once a symbol is stable, it may get
extended with new features in ways that don't break
compatibility with older ABI & API.

The mydist target runs validate_map.sh which should
catch some probable problems in liblzma.map. Otherwise
I would forget to update the map file for new releases.
