The C library doesn't use const char pointers for legacy reasons (and
because you *can* modify the string the end pointer points to), but
let's do it in our internal implementation just because it's a nice
guarantee to have.
We actually used to have a non-const end pointer and replace a decimal
comma with a decimal dot, but that was because we didn't have the fancy
"allow commas" flags. So by using our own strtod_flags() function, we
can now keep all the strings we parse read-only rather than modify them
as we parse them.

We'll want to do sane parsing of strings, but the C library makes it
hard to handle user input sanely and the Qt toDouble() function
interface was designed by a retarded chipmunk.
So just extend our existing hacky "ascii_strtod()" to allow a more
generic interface.
