0d4c885abb refactored --list function 
better handling of special conditions,
better scoping of variables.

Also : updated man page

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 
for potential redirection, if need be.

note : should probably converge all comparison operations onto CMP

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`.

ac5d2629c1 added a fake initialization to please an analyzer 
which is unable to understand that the variable is necessarily initialized
in spite of an assert just before.

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().

in exceptional conditions involving multiple flushes
triggered by -s3421 -t462948.

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.

2ece0d8380 created LZ4_initStream() 
- promoted LZ4_resetStream_fast() to stable
- moved LZ4_resetStream() into deprecate, but without triggering a compiler warning
- update all sources to no longer rely on LZ4_resetStream()

note : LZ4_initStream() proposal is slightly different :
it's able to initialize any buffer, provided that it's large enough.
To this end, it accepts a void*, and returns an LZ4_stream_t*.

c491df54ec created LZ4_initStreamHC() 
- promoted LZ4_resetStreamHC_fast() to stable
- moved LZ4_resetStreamHC() to deprecated (but do not generate a warning yet)
- Updated doc, to highlight difference between init and reset
- switched all invocations of LZ4_resetStreamHC() onto LZ4_initStreamHC()
- misc: ensure `make all` also builds /tests
