note : it's unlikely to improve speed, as in most cases I/O is slower than lz4 decompression,
but maybe in extreme scenarios, it might show a difference.
makes it possible to replace at link time
malloc, calloc and free
by user-provided functions
which must be named LZ4_malloc(), LZ4_calloc() and LZ4_free().
answer #937
It's now possible to select a custom LZ4_DISTANCE_MAX at compile time,
provided it's <= 65535.
However, in some cases (when compressing in byU16 mode),
the new distance wasn't respected,
as it used to implied that it was necessarily within range.
Added a distance check for this case.
Also : added a new TravisCI test which ensures that
custom LZ4_DISTANCE_MAX compiles correctly
and compresses correctly (relying on `assert()` to find outsized offsets).
- 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
Improve formatting
Include static assert
Use UTIL_fseek to handle potential fseek limitation
Be explicit when refusing to read from stdin
Properly free dctx after use
Include valgrind tests
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.

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.
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`.
