Remove extra const qualifiers.

Some function declared parameters like this:
	int f(const char * const s)
Where appropriate, I changed to
	int f(const char *s)

The second const is a qualifier on the pointer itself; i.e., the value
of s may not be changed (may not be made to point to anything else)
within the function. This is probably not what was intended. The first
const is what prevents modifying things referenced through s.
