common base class for client_buffer and host_buffer

[armin]

client_buffer and host_buffer have both one thing in common: They have both a local user object, but there is no way to access it by the buffer base class. We should introduce a local_buffer class or something that inherits from buffer and has a local user. client_buffer and host_buffer may inherit from local_buffer and users can hold a local_buffer to access the local user object.
