33a04fb8bd fullbench: ensure decompressionFunction and dName are initialized 
Visual Studio seems to miss that they are necessarily initialized in the switch() { case: }

89c97d5ea6 fullbench: added test scenario LZ4F_decompress_followHint 
This emulates a streaming scenario,
where the caller follows rigorously the srcSize hints
provided as return value of LZ4F_decompress().

This is useful to show the issue in #714,
where data is uselessly copied in a tmp buffer first.

e2527ad725 updated tests 
- only play listTest with `make test`, not `make all` which is limited to build
- update `clangtest`, so that it's possible to disable O3 optimization, for faster processing

10726d4c56 test-amalgamation: use a single cat command 
Use the list of prerequisites instead of listing those files manually,
this way they will never fall out of sync.

Also update the amalgamation example to use a single cat command.

7136489d33 More build imrpvements 
Moved a few other tests to Makefiles.inc.  Other things might need to go there.
Made a test for symlink appropriateness.  Windows can NOT handle them the same way Unix-like operating systems do (if at all).  This is mostly the same as the Visual C projects.
embed version info into .dll and .exes that are redistributed.

22fae16c6f ensure tests work when stdout is not the console 
ensure this case is continuously tested on travis.

Update documentation on implicit output,
invite to not rely on implicit output in scripts.

467e352de9 tests/Makefile : created CMP variable

5f8ac02b77 cli: display a warning whenever default output is stdout while input != stdin 
This behavior has been preserved for compatibility with existing ecosystem.
But it's problematic, as some environment start `lz4` without identifying stdout as console by default,
leading to a change of behavior for a same line of script.

A more sensible policy would be to default to stdout only when input is stdin.

Soft change for the time being : keep the behavior, just print a warning message.
User should prefer `-c` to explicitly select `stdout`.

Also : updated tests in Makefile to explicitly select `stdout` with `-c`.

ce0f316989 fix fuzzer tests on dirty context 
context is no longer dirty after a failed compressed block.
Actually, all indexes are fine.
It remains compatible with continued streaming, and reset*_fast().

20c2a5fc94 added command -BI for "Independent Blocks" 
This is the reverse of `-BD`, and the current default.

This command can be useful to reverse a previous `-BD` command.
It may in the future be more important
if `lz4` switches to generating dependent blocks by default.

14c71dfa9c modified LZ4_initStreamHC() to look like LZ4_initStream() 
it is now a pure initializer, for statically allocated states.
It can initialize any memory area, and because of this, requires size.
