ipi(9): Convert membar_exit/enter to membar_release/acquire.

No store-before-load ordering needed here, just need to ensure that
in

	A, ipi_send, ipi receive, B,

memory operations in A happen-before memory operations in B.

ipi: Split up initialization into two parts.

First part runs early so ipi_register can be used in module
initialization, e.g. via pktqueue_create; second part runs after CPUs
have been detected.

Add void * function pointer casts. There are different ways to "fix" those
warnings:
    1. this one: add a void * cast (which I think is the least intrusive)
    2. add pragmas to elide the warning
    3. add intermediate inline conversion functions
    4. change the called function prototypes, adding unused arguments and
       converting some of the pointer arguments to void *.
    5. make the functions varyadic (which defeats the purpose of checking)
    6. pass command line flags to elide the warning
I did try 3 and 4 and I was not pleased with the result (sys_ptrace_common.c)
(3) added too much code and defines, and (4) made the regular use clumsy.

Add an ipi_trigger_broadcast() call, like ipi_trigger_multi() but to the
full set of attached CPUs, with an optional "skip_self" argument to skip
the calling CPU.  Add a "skip_self" to the ipi_broadcast() call for
symmetry.

(Kernel version bump coming in a subsequent commit.)

MI IPI interface:
- Implement support for the asynchronous IPI calls.
- Rework synchronous IPI code to reuse the asynchronous mechanism.
- Add ipi(9) manual page; needs wizd(8).

Note: MD code can now provide a low level primitive for the ipi(9) and
reuse this interface instead of open-coding.  Portmasters are encouraged
to convert.  Ride 6.99.43!
