8cbb7f101f Kernel: Have File virtuals take a FileDescriptor& rather than a Process&. 
This will allow us to implement different behaviors depending on the role
of the descriptor a File is being accessed through.

5c68929aa1 Kernel: Add a systrace() syscall and implement /bin/strace using it. 
Calling systrace(pid) gives you a file descriptor with a stream of the
syscalls made by a peer process. The process must be owned by the same
UID who calls systrace(). :^)
