remove pointer to long conversions - part 2 of 3 (trunk only)

Remove some more code that forced pointers into a long int, and
vice versa where information could be lost (P64 platforms such as
WIN64 have a 64 bit pointer size, but a 32 bit long size.)

This 2nd part deals with timeout functions switching
some arguments from type genericptr_t to 'anything'.

Like part 1, this needs to increment EDITLEVEL in patchlevel.h.
