eda8c4eb1c fix #198 : no longer requires to restart streaming decompression from where it stopped. 
It permits relocating remaining data into another memory space.
Still, the same content must be presented.

012c66536c Add LZ4LIB_API 
It's based on Zstandard's ZSTDLIB_API.

See also: https://github.com/Cyan4973/lz4/issues/216#issuecomment-226245432

Deprecated functions aren't LZ4LIB_API targets. Because we don't need to
export deprecated functions from now.

There are same LZ4LIB_API definitions in each header files instead of
including a common header file because LZ4_DEPRECATED is defined so.

dc868cd5b1 Allow for safe in-place decoding 
Add a check to allow safe "in-place" decoding (meaning that the
beginning of the source buffer partially overlaps the end of the
destination buffer). This is usually possible as long as the output
stops at least 15 bytes before the end of the input buffer (7 to account
for the extra spill from LZ4_wildCopy, 4 for a possible block checksum,
and 4 for the terminating block header), but in some pathological edge
cases it could be possible for the output stream to overwrite a byte in
the input stream before it gets decoded. With this patch the decoder
will reliably detect those cases and return a decoding error.
