Add lzma compression support.

* NEWS: Mention it.
* automake.in (handle_dist): Recognize dist-lzma.
(make_paragraphs): Map LZMA to dist-lzma.
* doc/automake.texi (Dist): Add dist-lzma.
(Options): Likewise.
* lib/Automake/Options.pm (_process_option_list):
* lib/am/distdir.am (dist-lzma): New rule.
(dist dist-all): Add command to create an lzma-compressed tarball.
(distcheck): Handle lzma-compressed tarballs just like the others.
* tests/defs.in: Test for lzma, too.
* tests/lzma.test: New file, based on nogzip.test.
* tests/Makefile.am (TESTS): Add lzma.test.
* tests/Makefile.in: Regenerate.
Suggestion from Karl Berry.
