* Fix an overrun in sparse block detection.
* Fix an off-by-one memory handling issue in ddr_lzo, resulting
in breakage on s390x. (Surprisingly, glibc memory allocator
was graceful on most architectures.)
* Better test coverage, including chains with sparse files.
* Documented (and somewhat cleaner) design of handling sparse
files through chains of plugins.
* Test and support compression+encryption (and reverse
decryption+decompression) chains.
* Improved debug output, including numbering plugins.
- Update to dd_rescue-1.99.19:
* ddr_crypt: Clean hole support with and without skiphole.
(This works cleanly only for CTR and ECB modes.)
* ddr_crypt: Fix backwards copies including holes. Note that
this could result in different files from the forward copies
before (bug). Add test case for the latter.
* Many more testcases for sparse files with plugins: Also use
odd sizes and holes at the beginning and end of the file.
* Also skip over holes with -a when copying in reverse dir.
* Allow setting unsparse and some other flags for ddr_null for
testing.
* Fix lzma compression with hole at the end.
* Warn on lzma buf error (was debug msg only before).
