Add kernel support for having userland provide the signal trampoline:
...
* struct sigacts gets a new sigact_sigdesc structure, which has the
sigaction and the trampoline/version. Version 0 means "legacy kernel
provided trampoline". Other versions are coordinated with machine-
dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions. Instead,
sendsig() looks up the handler by peeking in the sigacts for the
process getting the signal (since it has to look in there for the
trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
its arguments based on the trampoline version in the sigacts.
Changes to libc to use the new facility will be checked in later. Kernel
version not bumped; we will ride the 1.6C bump made recently.

When delivering a signal, arrange for the handler to be invoked
...
directly. The trampoline is now used only for the return, and
makes it another 2 instructions shorter.

When delivering a signal, don't push the signum, code, and context pointer,

or handler onto the stack. Instead, just stuff them into the correct
argument registers (handler is a "4th arg").

Make CLKF_INTR() slightly less broken. The previous definition always

tested true if the CPU was running in the kernel at the time of the clock
interrupt, therefore all such time (kernel and idle) was counted as interrupt
time. The new definition simply punts on trying to count interrupt time,
which allows us to see kernel and idle time.
