Subject: [PATCH] Run the headers through cpp -dM to find the #defines.  The
 direct search has been broken at least since 4.4Lite moved most of the
 #defines out of <sys/ioctl.h>.  This should be done better.  Only a few
 headers are searched.

Added some #includes so that ioctl.c compiles.  The networking headers
have a maze of undocumented interdependencies and ioctl.c now actually
supports networking ioctls.
