We should make sure that the prototypes match the implementations and
thus include the alloc_page.h header from alloc_page.c, and the

compiled with -Wmissing-prototypes and -Wstrict-prototypes, too.

lib: simplify alloc_ops

Layer malloc/calloc/free/memalign over a basic allocator.
The implementation of high-level routines remains the basic one
from before, but the callback interface is reduced to a single
function. Since alloc.c now contains the physical address allocator
only, rename it.

Done with `sed -i 's/0x%/%#/g' **/*.[ch]` to motivate the use of %#,
existing padding was raised by 2 to account for the counted "0x" (output
should be the same).

This is a fix just due to being too much of a type-A person.
I noticed the issue while reading over the function, and
decided to fix it, even though it's unlikely to be a problem
ever because top is read-mostly (like written once, then only
read, type of mostly).

Introduce lib/alloc

alloc supplies three ingredients to the test framework that are all
related to the support of dynamic memory allocation.

The first is a set of alloc function wrappers for malloc and its
friends. Using wrappers allows test code and common code to use the
same interface for memory allocation at all stages, even though the
implementations may change with the stage, e.g. pre/post paging.

The second is a set of implementations for the alloc function
interfaces. These implementations are named early_*, as they can be
used almost immediately by the test framework.

The third is a very simple physical memory allocator, which the
early_* alloc functions build on.
