+// decompress an LZ4 block
+// Parameters:
+//      @in         -   Input buffer containing an LZ4 block.
+//      @in_size    -   Size of the input LZ4 block in bytes.
+//      @out        -   Output buffer to hold decompressed results.
+//      @out_size   -   The size of the buffer pointed to by @out.
+// Invariants:
+//      @in         -   This buffer must be at least 1 machine word in length,
+//                      regardless of the actual LZ4 block size.
+//      @in_size    -   This must be at least 4 and must also be <= to the
+//                      allocated buffer @in.
+//      @out        -   This must be bigger than the input buffer and at least
+//                      13 bytes.
+//      @out_size   -   Must always be big enough to hold the expected size.
+// Return:
+//      -1          -  Decompression failed.
+//      size        -  Actual number of bytes decompressed.
