e45ef6abcd Emulate the Linux DVD_* ioctls(2). This gets us 90% of the way to running the 
LiViD DVD player.  (See forthcoming mail to current-users.)
XXX NOTE: We should do something to probe capabilities, rather than allowing
these ioctls on any device.

c581bf97c5 A few things to make the Linux clone(2) emulation work a bit better: 
- When the exit signal is specified to be 0, don't just assume they
  meant SIGCHLD.  In the Linux world, this appears to mean "don't deliver
  an exit signal at all".
- Simplify P_EXITSIG(); don't check against initproc here, just change
  the exit signal to SIGCHLD if reparenting to initproc.

A very simple clone(2) test program now works, and the MpegTV package
starts, but doesn't run properly yet (I believe there is a separate
bug which keeps it from working properly).

e3669c3393 Add "use counting" to file entries. When closing a file, and it's reference 
count is 0, wait for use count to drain before finishing the close.

This is necessary in order for multiple processes to safely share file
descriptor tables.

af8a9059d3 compute the value to be used for e_arglen via howmany(value, sizeof (char *)), 
rather than just "value / sizeof (char *)".  While in these cases the latter
works as well, the former's a better example for other uses to copy (since
it handles the non-integral multiple case correctly).

Because "linux_ipccall.h" cannot be included before "sys/shm.h" and
