Message:

Convert call-handling syscalls to capabilities

This commit modifies the behavior of sys_ipc_wait_for_call() to return a
capability handle for requests. This capability handle can be used
either by sys_ipc_answer*() to answer the call or by sys_ipc_forward*()
to forward it further along. Answering or forwarding the call results in
destruction of the respective capability. For requests and
notifications, sys_ipc_wait_for_call() returns CAP_NIL and sets call
flags accordingly.
