* Added BSD specific errno.h for EDOOFUS (yeah, I know, great error code...)

* Added sigmask() macro.
* Fixed libutil.h I broke yesterday: it's thought to add functions only if
  you've included some other headers before; added the correct header guard
  we're using for our sys/param.h.
* Added pidfile.c to the build.
* Fixed warning in realhostname.c, and pidfile.c.
