This series aims to provide a possibility to build Xen without mem_access and
related features. It is already largely covered by corresponding
CONFIG_MEM_ACCESS option, yet there're still some parts remaining.
Hopefully this would help to reduce dead code a bit.

As coverage of MEM_ACCESS config option begins to extend beyond actual
mem_access code it has been suggested to rename it into VM_EVENT, as a more
general option controlling mem_access, vm_event and monitor code.

One patch for automation from v2 series had been squashed into #1 patch in
v3 series, v2 reference below:
