6d5dec35b7 Add the rest of the kernel support for the sem_ API in kern/uipc_sem.c. 
Option 'P1003_1B_SEMAPHORES' to compile them in, or load the "sem" module
to activate them.

Have kern/makesyscalls.sh emit an include for sys/_semaphore.h into sysproto.h
to pull in the typedef for semid_t.

Add the syscalls to the syscall table as module stubs.

efaa658806 Bring in my implementation of kernel support for posix realtime semaphores 
that are shareable between processes.

There will be a cleanup shortly along with the necessary changes made to
libc, libc_r, libpthread as well as the hooks into sys/conf and sys/modules.

2201e1b039 Optimize the way we call BPF a tiny bit: If we chop the ether-header off 
ourselves, call bpf before we do so, rather than re-construct the entire
thing afterwards.

f0e2422b1b Use m_length() instead of home-rolled. 
In bpf_mtap(), if the entire packet is in one mbuf, call bpf_tap()
instead since it is a tad faster.

fa55172bc0 Guido reported an interesting bug where an FTP connection between a 
Windows 2000 box and a FreeBSD box could stall.  The problem turned out
to be a timestamp reply bug in the W2K TCP stack.  FreeBSD sends a
timestamp with the SYN, W2K returns a timestamp of 0 in the SYN+ACK
causing FreeBSD to calculate an insane SRTT and RTT, resulting in
a maximal retransmit timeout (60 seconds).  If there is any packet
loss on the connection for the first six or so packets the retransmit
case may be hit (the window will still be too small for fast-retransmit),
causing a 60+ second pause.  The W2K box gives up and closes the
connection.

This commit works around the W2K bug.

1822cdcafe It seems I accidently committed a change that removed the userland includes 
from the kernel build.  This broke linux_genassym on the alpha.  For the
kernel, the correct place to get offsetof() is not in /usr/include/stddef.h
but rather <sys/types.h>

117f87fe9f Include <sys/types.h> directly rather than depending on <sys/fcntl.h> 
to include it.  This could be avoided by adding the necessary typedefs
here, or by making users of <sys/file.h> include <sys/types.h> first.
