Fixed a couple of nitpick warnings, plus one that slipped through the
net earlier.
This directory now compiles without any warnings with -Wall! (Until
the next gcc upgrade...)
1. Added missing function prototypes.
2. Added missing function return types.
3. Added missing function argument types.
4. Added missing headers for system function prototypes.
5. Corrected casts in select() args.
6. Got rid of more "extern int errno" rubbish.
7. Added extra parentheses around assignment used as truth value.
8. Fixed bug in clnt_{tcp, udp}create() where pointers could be free'd
even if they hadn't been successfully malloc()'d.
but a commit mail got lost, it's the same as for this commit:

Minor cleanup, mostly unused vars and missing #includes.
Limit the number of quad functions we pull in for 'i386'.
I still belive the quad stuff should go back into gcc.
Add compile-time warnings about crypt functions.
