a8dd86d93e changed macro HEAPMODE into LZ4_HEAPMODE
This macro is susceptible to be triggered from user side
typically through compiler flag (-DLZ4_HEAPMODE=1).
In which case, it makes sense to prefix the macro
since we want to reduce potential side-effect on namespace.

e2827775ee make __packed memory access default for gcc
It's always as good or better then memcpy()
but depends on gcc-specific extension.

cd35f0d98c LZ4_compress_HC_destSize() uses LZ4HC_compress_generic() code path
Limits compression level to 10,
to remain compatible with Hash Chain.

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.
