Do the actual idling in protected mode. This both allows PM code a
more efficient interface, but also handles bugs in HVM implementations
which don't handle HLT in real mode.

The 16-bit API to opendir/readdir/closedir was confused, had a memory
leak, and was incompatible with Syslinux 3.x anyway. Replace it with
a pure 32-bit API.

Use a better malloc for the core. In particular, use the same core
that we should eventually be able to use for the entire system in
Syslinux 5 -- with module awareness, etc.
This code can also accommodate multiple heaps. Set up a separate heap
for lowmem; the intent is to use explicit lowmem allocations instead
of the static bounce buffer. The lowmem allocation is also exported
via the pmapi mechanism, so modules can safely allocate lowmem.

Add a direct 32-bit API to some functions; initially read file only.
