When constructing a thread object its capability is inserted into the capability map. Normally this is done by the ipc-unmarshalling code, but in this case the thread-capability isn't transfered via normal IPC, but in a special form via the thread_state object. In contrast to the unmarshalling code, the thread-startup code doesn't check, whether the capability-map already contains a deprecated entry with the same capability id before inserting the thread's capability. This commit add the necessary check. Moreover, a check is added to the insertion methods of the capability-map to verify that capability-allocation didn't failed.
