util: Add a virtual memory allocator
This is simple linear-walk first-fit allocator roughly based on the
allocator in the radeon winsys code. This allocator has two primary
functional differences:
1) It cleanly returns 0 on allocation failure
2) It allocates addresses top-down instead of bottom-up.
The second one is needed for Intel because high addresses (with bit 47
set) need to be canonicalized in order to work properly. If we allocate
bottom-up, then high addresses will be very rare (if they ever happen).
We'd rather always have high addresses so that the canonicalization code
gets better testing.
v2: - [scott-ph] remove _heap_validate() if NDEBUG is defined (Jordan)
