Changes to start making the tree use the new memory system. Trying to compile decoder.cc but fails still.
SConscript:
Place the memory objects back in the right place
arch/alpha/isa_desc:
Fix includes to point to the new memory requests
cpu/exec_context.hh:
Exec context now points to memory object, fix the include paths.
Convert to prot_read/prot_write functions instead of read and write.
Convert to new CpuRequestPtr instead of MemReqPtr.
mem/request.hh:
Add back in support for Request Flags (needed by decoder to tag request) Removed the flags that were associated with packets/coherence.
sim/process.hh:
Converted to point to new memory objects
