LDBL_MAX is broken on i386:
https://lists.freebsd.org/pipermail/freebsd-numerics/2012-September/000288.html
Gcc has produced +Infinity for LDBL_MAX on i386 and amd64 with -m32
for some time, and newer versions of gcc are now warning that the
"floating constant exceeds range of 'long double'". Avoid this by
referring to half the value of LDBL_MAX instead.

removes the only reference to atrtc_set() from outside of atrtc.c, so make
it static.
The xen timer driver registers as a realtime clock with 1us resolution. In
the past that resulted in only the xen timer's clock_settime() getting
called, so it would call atrtc_set() to set the hardware clock as well. As
of r32090, the clock_settime() method of all registered realtime clocks gets
called, so the xen driver no longer needs to chain-call the lower-resolution
driver.
Thanks to royger@ for talking me through the xen stuff, and for testing.

When the mps(4) and mpr(4) drivers need to reinitialize the
firmware, they sometimes need to reallocate all of the memory
allocated by the driver. The reallocation happens whenever the IOC
Facts change. That should only happen after a firmware upgrade.
If the reinitialization happens as a result of a timed out command
sent to the card, the command that timed out and triggered the
reinit may have been freed if iocfacts_allocate() reallocated all
memory. If the caller attempts to access the command after that,
the kernel will panic because the caller will be dereferencing
freed memory.
The solution is to set a flag in the softc when we reallocate,
and avoid dereferencing the command strucure if we've reallocated.
The changes are largely the same in both drivers, since mpr(4) is a
derivative of mps(4).
o In iocfacts_allocate(), if the IOC Facts have changed and we
need to reallocate, set the REALLOCATED flag in the softc.
o Change wait_command() to take a struct mps_command ** instead of
a struct mps_command *. This allows us to NULL out the caller's
command pointer if we have to reinit the controller and the data
structures get reallocated. (The REALLOCATED flag will be set
in the softc if that has happened.)
o In every place that calls wait_command(), make sure we handle
the case where the command is NULL after the call.
o The mpr(4) driver has mpr_request_polled() which can also
reinitialize the card. Also check for reallocation there.

It appears I misunderstand process forking and signal handling in
how the pre-/post-install scripts are executed internally by pkg(8).
In some cases (not all), ^C when prompted to cancel the kernel
package update will stop the pre-install script from executing, but
allow pkg(8) to continue extracting the package when it is not the
intent.

ASSUME_ALWAYS_YES is false and TERM is set, then sleep for 5 seconds
