lz4: Decrease indentation, a flat flow reads better
lz4: move match_len &= line to immediately before it's needed
lz4: Move the fastpath (when lit_len is 0) jump to the end of the loop
Declare variables on one row
lz4: In src vs src_end check, move constants to right side
fix makefile
lz4: Do not check match_off != 0

This is a corrupt archive and not a buffer over/underflow problem. There
are many ways for an archive to go corrupt undetected, so checking this
is out of scope.
lz4: Fix src bounds checking (allow 2-byte lit hunk for a 1-byte file)
lz4: Rename buffers to descriptive names txt_buf and lz_buf
lz4: Return error code from LZ4_decompress
lz4: Style, use C convention of dst, src argument order. Use lowercase lz4
lz4: remove unneeded braces
lz4: Add comments for lz4 compress/decompress
