	src/sys/net: if_gre.c if_gre.h

Log Message:
Switch from spl(9) to mutex(9) and condvar(9).

Fix a defect in the locking of file descriptors as we delegate a
UDP socket from userland to the kernel.  Move sc_fp out of sc_soparm.
Synchronize access to sc_fp by gre_ioctl() and the kernel thread
using a condition variable.  For simplicity's sake, make it the
kernel helper thread's responsibility to close its UDP socket.
