Further modernize Hurd code by enforcing strict prototypes and no implicit function declarations.

Most of the changes land in one of these buckets:
* Removed unused declarations.
* Used (void) to represent no parameters instead of () which means an
  undeterminate number of parameters.
* Included missing header files whenever necessary (stdlib.h,
  sys/mman.h, etc)
* Typedefed function pointers to be able to fully declare the parameter
  types.
* Added declarations of library functions that are used elsewhere
  (example is libps/ps.h).
* Made functions static whenever they are only used in that file.
* Forwarded declarations of some methods that were made static.
