Log:
(Forced commit, to clarify previous commit of ksiginfo/signal queue code.)
I've added a structure, kernel-private, to represent a pending or in-delivery
signal, called `ksiginfo'. It is roughly analogous to the basic information
that is exported by the POSIX interface 'siginfo_t', but more basic. I've
added functions to allocate these structures, and further to wrap all signal
operations using them.
Once the operations are wrapped, I've added a TailQ (see queue(3)) of these
structures to 'struct proc', and all pending signals are in that TailQ. When
a signal is being delivered, it is dequeued from the list. Once I finish
the spreading of ksiginfo throughout the tree, the dequeued structure will be
delivered to the process in question, whereas currently and normally, the
signal number is what is used.
