Moved most buffer debug messages to DBG2.
Make expand_buffer() a non-inline function, so that we can add debug
messages.
Expandable buffers now don't *always* round up to the next power of two.
This allows e.g. loading a 137MB ISO image on a machine with only 256MB
RAM...

We don't actually have a stdio.h header file. Our printf() functions are
defined in vsprintf.h. (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)
There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.

Start of an implementation using doubly-linked lists and virtual
addresses. This will have to be reworked to use physical addresses thanks
to the PXE spec.
