This patch replaces exceptions of the PD session RPC interface with result types. The change of the quota-transfer RPC functions required the adaptation of base/quota_transfer.h and base/child.h. The 'alloc_signal_source' method has been renamed to 'signal_source' to avoid an exceedingly long name of the corresponding result type. The Pd_session::map function takes a 'Virt_range' instead of basic-type arguments. The 'Signal_source_capability' alias for 'Capability<Signal_source>' has been removed. Issue #5245
