cc, ?[acl]: fix gethunk() and move common memory allocator code to cc/compat

for gethunk() to work, all allocators have to use it,
including allocations done by libc thru malloc(),
so the fake allocation functions are mandatory for
everyone.

to avoid duplication the code is moved to cc/compat
and prototypes provided in new cc/compat.h header.
