+
+Add xbzrle_encode_buffer and xbzrle_decode_buffer functions
+
+ For performance we are encoding long word at a time.
+ For nzrun we use long-word-at-a-time NULL-detection tricks from strcmp():
+ using ((lword - 0x0101010101010101) & (~lword) & 0x8080808080808080) test
+ to find out if any byte in the long word is zero.
