Review manager wanted: core.vmm

[Dmitry Olshansky via Digitalmars-d]

The module aims to provide portable interface to virtual memory 
management unit of the OS. Some common recipes such as locking memory 
and allocating executable memory should be easily accessible.

In general the task is next to impossible and therefore capabilities of 
the current OS are captured into manifest constant to allow for 
conditional adaptation to them (static ifs etc).
