Enable forwarding of IPC_M_AS_AREA_SEND, IPC_M_AS_AREA_RECV, IPC_M_DATA_SEND
calls. In order to prevent the forwarder from cloberring the call data (i.e.
source and destination address, and size) by treating these three methods as
immutable on forward. This feature is experimental, but has huge benefits in
that it can significantly reduce the amount of data sharing (the middle man need
not modify its address space mappings) or the amount of data copying (the middle
man need not receive the data from the sender and then resend them to the next
recipient). As a result, it can reduce N such calls for a communication channel
with N tasks along the way to 1 such call.

jermar – 3 file(s) modified
Implement a new mechanism for copying data between two address spaces based on
IPC. New system method IPC_M_DATA_SEND is introduced. The implementation is
generic and does not make use of any possible architecture optimizations such as
direct copy from one address space to another.
