- Removing some unneeded definitions of NULL(cruft related to 1970's C).

  In C90, NULL is guaranteed to be declared in <stddef.h> and also in
  <string.h>.  Though the correct way to define NULL in FreeBSD is to
  include <sys/_null.h>, other parts of libstand still require <string.h>
  to build; therefore, we keep <string.h> in stand.h and add a note about
  this;
- Removing no longer used 'Prototype' definition.  Quote from bde@:

	'Cruft related to getting incomplete struct declarations within
	prototypes forward-declared before the structs.  It doesn't mean
	"prototype" but only part of a prototype-related hack.  No longer
	used.'

- Replacing iaddr_t with uintptr_t;
- Removing use of long double to determine alignment.  Use a fixed 16 byte
  alignment instead;
