Internet: Preemptive casts ahead of header changes

Detail:
  The iov_base will be changing from char to void pointer in future,
  preemptively insert a cast in 'kern_subr.c' to prevent compiler errors.
  Move svcdebug.h here from TCPIPLibs since its only (private) implementation
  is this component, and remove unused includes of 'ioc.h' and 'int_hndlr.h'.
Admin:
  Submission for TCP/IP bounty.
