Move include/malloc.h to include/gpxe/malloc.h, since everything in there
is now gPXE-specific. (The standard malloc() et al have been in stdlib.h
for a while).
Add free memory counter.

Don't always zero memory in malloc(). This saves around 2us on a
full-length PKB allocation.

Implemented realloc(), and changed the semantics of malloc(0) to allow
for realloc(0) being a valid way to free memory.

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.

Removed incorrect comment; malloc() is inefficient only when the
alignment and size are both powers of two, and there's no way to
specify an alignment through the malloc() interface anyway.

Now passes trivial tests. free_memblock() needs neatening up.

Updated memory allocator to improve support for unaligned or partially
aligned blocks.
Moved header to include/malloc.h, since we now also provide the
POSIX-like malloc()/free() pair.
Not yet tested.
