* Version 1.12 released.
* lzlib.h: Define LZ_API_VERSION as 1000 * major + minor. 1.12 = 1012.
This change does not affect the soversion.
* lzlib.h, lzlib.c: New function LZ_api_version.
* LZd_try_verify_trailer: Return 2 if EOF at trailer or EOS marker.
* Decompression speed has been slightly increased.
* decoder.h: Increase 'rd_min_available_bytes' from 8 to 10.
* encoder_base.c (LZeb_try_sync_flush):
Compensate for the increase in 'rd_min_available_bytes'.
* main.c (do_decompress): Fix false report about library stall.
* main.c: New option '--check-lib'.
* main.c (main): Report an error if a file name is empty.
Make '-o' behave like '-c', but writing to file instead of stdout.
Make '-c' and '-o' check whether the output is a terminal only once.
Do not open output if input is a terminal.
Replace 'decompressed', 'compressed' with 'out', 'in' in output.
Set a valid invocation_name even if argc == 0.
* lzlib.texi: Document the new way of verifying the library version.
Document that 'LZ_(de)compress_close' and 'LZ_(de)compress_errno'
can be called with a null argument.
Document that sync flush marker is not allowed in lzip files.
Document the consequences of not calling 'LZ_decompress_finish'.
Document that 'LZ_decompress_read' returns at least once per member.
Document that 'LZ_(de)compress_read' can be called with a null
buffer pointer argument.
Real code examples for common uses have been added to the tutorial.
* bbexample.c: Don't use 'LZ_(de)compress_write_size'.
* lzcheck.c: New options '-s' (sync) and '-m' (member by member).
Test member by member without 'LZ_decompress_finish'.
* ffexample.c: New file containing example functions for file-to-file
compression/decompression.
* Document extraction from tar.lz in '--help' output and man page.
* Makefile.in: 'install-bin' no longer installs the man page.
New targets 'install-bin-compress' and 'install-bin-strip-compress'.
* testsuite: Add 9 new test files.

* cbuffer.c (Cb_read_data): Allow a null buffer pointer.
* main.c: Don't allow mixing different operations (-d and -t).
* main.c: Check return value of close( infd ).
* main.c: Compile on DOS with DJGPP.
* lzlib.texi: Improved descriptions of '-0..-9', '-m' and '-s'.

Document that 'LZ_(de)compress_finish' can be called repeatedly.
* configure: Accept appending to CFLAGS, 'CFLAGS+=OPTIONS'.
* Makefile.in: Targets 'install-bin*' renamed to 'install-lib*'.
* Makefile.in: Rename targets 'install-bin*' to 'install-lib*'.
