new helper: get_signal()
On success get_signal_to_deliver() fills k_sigaction and siginfo.
_All_ users pass it addresses of the local variables sitting in
the same function. Then they proceed to pass those addresses
pretty much in tandem to a bunch of helper functions; again, all
callers of those helpers are passing them such a pair, and one that
had been through get_signal_to_deliver() at that.
The obvious cleanup: introduce a new type that would contain a
<k_sigaction,siginfo> pair (struct ksignal) and begin switching to
using it. Turns out that it's convenient to store the signal number
in the same object.
New helper, taking that sucker is a wrapper for get_signal_to_deliver();
takes struct ksignal * and returns bool. On success fills ksignal
with the information for signal handler to be invoked.
For now it's a macro (to avoid header ordering headache), but eventually
it'll be a function in kernel/signal.c, with get_signal_to_deliver()
folded into it.
