Yet another redis proxy based on codis

Please read codis document first. here

• Install Go and set your GOPATH
• Install godep go get github.com/tools/godep
• go get github.com/siddontang/xcodis, it will print some messages in console, skip it. :-)
• cd $GOPATH/src/github.com/siddontang/xcodis
• make

• Supports LedisDB.
• Supports origin Redis, codis uses a modified version.

• Uses db index to represent slot concept in codis.
• Uses server + db as the connection pool key.
• slot_num in config must equal redis/ledisdb databases. 16 is the default for redis and ledisdb, if you want to use larger one, you must first change redis/ledisdb databases in config.
• Uses scan + migrate in redis for slot migration.
• Uses xmigrate + xmigratedb in ledisdb for slot migration.
• Removes dashboard.
• Removes slot rebalance feature.
• Must set a broker in config.ini, broker is ledisdb or redis.
• Uses a white command list for ledisdb.
• Not support atomic tag migration.
• Not support lua for ledisdb.

• Tidy up some ugly codes I added. >_<

Thanks Wandoujia, codis is a very awesome application.
