misc: Make jit_note and related functions take a const argument

Browse source 
Make jit_memcpy, jit_memmove, jit_data take const pointers to
allow jit_note to be used with a const string (e.g. a string
literal, __FILE__ or __func__). This is needed for GNU Smalltalk
to silence compiler warnings.

Sadly "const jit_pointer_t" is not the same as "typedef const void *"
so I introduced a new typedef for a const jit pointer. The other
option would be to replace jit_pointer_t with void*.
