Added support for the Snappy compression algorithm which has shown to have considerably better compression speed than LZO at a comparable compression ratio. To enable Snappy add: compress snappy to both client and server config files. Alternatively, enable compression framing on the client: compress and have the server selectively push "compress snappy" to the client. This change also extends the client capability handshake to include IV_SNAPPY so the server can be aware that a connecting client supports Snappy. Note that the Snappy implementation also includes an improved framing approach where the first byte of the compressed payload is replaced by the compression control byte (the first payload byte is moved to the end of the packet). This solves off-by-one alignment issues, which improves performance on ARM. By default, the configure script will try to build with Snappy support. To disable, use the --disable-snappy option. The --enable-lzo-stub configure directive is now --enable-comp-stub (because it's not actually "lzo" but "compression-enabled packet framing") Add compression overhead to extra buffer unconditionally, as long as USE_COMP is defined.
