* Introduced {malloc,memalign,free}_etc() which take an additional "flags"

argument. They replace the previous special-purpose allocation functions
  (malloc_nogrow(), vip_io_request_malloc()).
* Moved the I/O VIP heap to heap.cpp accordingly.
* Added quite a bit of passing around of allocation flags in the VM,
  particularly in the VM*AddressSpace classes.
* Fixed IOBuffer::GetNextVirtualVec(): It was ignoring the VIP flag and always
  allocated on the normal heap.
