Fixed world breakage on systems where ntohl() doesn't return u_long

(e.g., on alphas, or even on i386's with a POSIX-200x-conformant
ntohl() (ntohl() returns uint32_t which is u_int on i386's)).

Fixed related bugs and bogons while I'm here:
- ntohl() was "fixed" for printing in 1 place by casting to
  "(unsigned int )".  This breaks the value on systems where u_int
  is smaller than uint32_t, and has 2 style bugs.
- spell u_int consistently (never use "unsigned").
- break K&R support some more (don't cast malloc()'s arg to a wrong
  type...).
