[JBoss JIRA] Created: (ISPN-244) Enable external user/framework defined Externalizers

Enable external user/framework defined Externalizers
----------------------------------------------------
Key: ISPN-244
URL: https://jira.jboss.org/jira/browse/ISPN-244
Project: Infinispan
Issue Type: Feature Request
Components: RPC
Reporter: Galder Zamarreno
Fix For: 4.1.0.BETA1
Create an internal magic number (i.e. -1 or 255) for user defined externalizers. This is done to avoid users using our number space.
So, internally: <magic_number> <stream>
Users: <magic_number><user defined magic number (int)> <stream>
Mandate unsigned ints so that we can optimise by sending them as variable lenght
Internal frameworks could use high enough numbers for example up to 2 bytes: 5000, 7000, 20000
1 byte: 128
2 bytes: 32767
3 bytes: ...
GlobalConfiguration.registerMarshallable(Class type, Externalizer ext, int id);
Maybe CacheManager better?
CacheManager.registerMarshallable(Class type, Externalizer ext, int id);
Future improvement, maybe generate ids automatically for user defined classes?
