memcached server incr/decr doesn't work in unsigned 64bit integer mode
----------------------------------------------------------------------

                 Key: ISPN-743
                 URL: https://jira.jboss.org/browse/ISPN-743
             Project: Infinispan
          Issue Type: Bug
          Components: Cache Server
    Affects Versions: 4.2.0.ALPHA4, 4.1.0.Final
            Reporter: Galder Zamarreño
            Assignee: Galder Zamarreño
             Fix For: 4.2.0.BETA1, 4.2.0.Final


[mlinhard at michal-linhard ~]$ telnet localhost 11211 
Trying 127.0.0.1... 
Connected to localhost. 
Escape character is '^]'. 
set a 0 0 19 
9223372036854775808 
STORED 
incr a 1 
SERVER_ERROR org.infinispan.server.core.ServerException: java.lang.NumberFormatException: For input string: "9223372036854775808" 

when I run original memcached server on port 11212 it works: 
[mlinhard at michal-linhard ~]$ telnet localhost 11212 
Trying 127.0.0.1... 
Connected to localhost. 
Escape character is '^]'. 
set a 0 0 1 
A 
STORED 
set a 0 0 19 
9223372036854775808 
STORED 
incr a 1 
9223372036854775809 

---------------- 
Other issue here is overflow: 
set a 0 0 19 
9223372036854775807 
incr a 1 
-9223372036854775808 

whereas original memcached server overflows in "unsigned mode": 
set b 0 0 20 
18446744073709551615 
incr b 1 
0
