Re: libc.lsh

malloc anf free in libc.lsh were meant to call the
C malloc() and free(), without memory management.
A *lot* of libraries use them.
I'm not sure what the alternative is in Lush2.

Leon introduced the constants mechanism to avoid crowding the
namespace, because constants extracted from a C header may
clash uncontrolably with existing symbols.

Also,  <at>  and  <at>  <at>  are different.  <at>  <at>  evaluates at read time (like #.) 
whereas  <at>  evaluates at compile time. It's not entirely clear that 
we absolutely need both, but they are different.
