This isn't perfect as the scripts can still fail if only
certain filters are disabled. This is still an improvement
as now "make check" has better behavior when all encoders
or decoders are disabled.
Grepping ../config.h is simple and fairly clean but it only
works if config.h was created. CMake builds don't create
config.h but they don't use these test scripts either.
Thanks to Sebastian Andrzej Siewior for reporting the problem.
Thanks to Jia Tan for the original patch which grepped xz
error messages instead of config.h.
I suspect that I used these in the original version because
Autoconf's manual describes that such a trick is needed in
some specific situations for portability reasons. None of those
situations listed on Autoconf 2.71 manual apply to these test
scripts though so this cleans them up.
test_compress.sh now takes one command line argument:
a filename to be tested. If it begins with "compress_generated_"
the file will be created with create_compress_files.
This will allow parallel execution of the slow tests.
Testing compression at level -4 now requires 48 MiB of free store at
compression time and 5 MiB at decompression time.

broken. API has changed a lot and it will still change a
little more here and there. The command line tool doesn't
have all the required changes to reflect the API changes, so
it's easy to get "internal error" or trigger assertions.
specification. Simplify things by removing most of the
support for known uncompressed size in most places.
There are some miscellaneous changes here and there too.
The API of liblzma has got many changes and still some
more will be done soon. While most of the code has been
updated, some things are not fixed (the command line tool
will choke with invalid filter chain, if nothing else).
Subblock filter is somewhat broken for now. It will be
updated once the encoded format of the Subblock filter
has been decided.
