27959b43ec LZ4F_decompress requires a valid dctx state 
This is now explicitly documented and asserted.
fix #927

3dd34df751 added target lz4-wlib 
variant of lz4 linking to liblz4 dynamic library

requires the dynamic library to expose static-only symbols (experimental API)

Example for #888

e07a37d712 added a test for LZ4F_compressEnd() 
which actively tries to make it write out of bound.
For this scenario to be possible,
it's necessary to set dstCapacity < LZ4F_compressBound()

When a compression operation fails,
the CCtx context is left in an undefined state,
therefore compression cannot resume.
As a consequence :
- round trip tests must be aborted, since there is nothing valid to decompress
- most users avoid this situation, by ensuring that dstCapacity >= LZ4F_compressBound()

For these reasons, this use case was poorly tested up to now.

86023f01f2 avoid final trailing comma for enum lists 
as detected in #485 by @JoachimSchneider.

Refactored the c_standards tests
so that these issues get automatically detected in CI tests.

4d61ebc9c8 modified formulation for LZ4F_compressBound() 
previous version used an intentional overflow,
which is defined since it uses unsigned type,
but static analyzer complain about it.

7aeecbff71 Explicitly set visibility of public API functions when gcc is used 
Windows builds already limit exporting of functions to those marked
with LZ4LIB_API tag.  The same behaviour could be achieved on other
platforms when a relatively fresh gcc is used.

This change assigns public visibility to all symbols marked with
LZ4LIB_API tag.  When the library is built in -fvisibility=hidden
mode, only these marked symbols will be exported.
