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.

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.

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.

b94aa0c838 liblzma: Try to use SHA-256 from the operating system.
If the operating system libc or other base libraries
provide SHA-256, use that instead of our own copy.
Note that this doesn't use OpenSSL or libgcrypt or
such libraries to avoid creating dependencies to
other packages.

This supports at least FreeBSD, NetBSD, OpenBSD, Solaris,
MINIX, and Darwin. They all provide similar but not
identical SHA-256 APIs; everyone is a little different.

Thanks to Wim Lewis for the original patch, improvements,
and testing.

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.

9c1b05828a Fix portability problems in mythread.h.
Use gettimeofday() if clock_gettime() isn't available
(e.g. Darwin).

The test for availability of pthread_condattr_setclock()
and CLOCK_MONOTONIC was incorrect. Instead of fixing the
#ifdefs, use an Autoconf test. That way if there exists a
system that supports them but doesn't specify the matching
POSIX #defines, the features will still get detected.

Don't try to use pthread_sigmask() on OpenVMS. It doesn't
have that function.

Guard mythread.h against being #included multiple times.

de678e0c92 liblzma: Add lzma_stream_encoder_mt() for threaded compression.
This is the simplest method to do threading, which splits
the uncompressed data into blocks and compresses them
independently from each other. There's room for improvement
especially to reduce the memory usage, but nevertheless,
this is a good start.

d119927475 liblzma: Don't create an empty Block in lzma_stream_buffer_encode().
Empty Block was created if the input buffer was empty.
Empty Block wastes a few bytes of space, but more importantly
it triggers a bug in XZ Utils 5.0.1 and older when trying
to decompress such a file. 5.0.1 and older consider such
files to be corrupt. I thought that no encoder creates empty
Blocks when releasing 5.0.2 but I was wrong.

71b9380145 liblzma: Validate encoder arguments better.
The biggest problem was that the integrity check type
wasn't validated, and e.g. lzma_easy_buffer_encode()
would create a corrupt .xz Stream if given an unsupported
Check ID. Luckily applications don't usually try to use
an unsupport Check ID, so this bug is unlikely to cause
many real-world problems.

9f0a806aef Revise mythread.h.
This adds:

  - mythread_sync() macro to create synchronized blocks

  - mythread_cond structure and related functions
    and macros for condition variables with timed
    waiting using a relative timeout

  - mythread_create() to create a thread with all
    signals blocked

Some of these wouldn't need to be inline functions,
but I'll keep them this way for now for simplicity.

For timed waiting on a condition variable, librt is
now required on some systems to use clock_gettime().
configure.ac was updated to handle this.
