sintrcnt/sintrnames which are symbols containing the size of the 2
tables.
- For amd64/i386 remove the storage of intr* stuff from assembly files.
This area can be widely improved by applying the same to other
architectures and likely finding an unified approach among them and
move the whole code to be MI. More work in this area is expected to
happen fairly soon.
No MFC is previewed for this patch.

Expand the debugger hook, db_show_uma, to display these results as well.
This has proven to be very useful in out of memory situations when
it is not known why systems have become sluggish or fail in odd ways.

Use ioctl() to get the window size in vmstat(8), and force a new
header to be prepended to the output every time the current window
size changes. Change the number of lines before each header to the
current lines of the terminal when the terminal is resized, so that
the full terminal length can be used for output lines.

- Fix overflow bugs in sysctl(8), systat(1), and vmstat(8)
when printing values of "struct vmmeter" in kilobytes as
they don't necessarily fit into 32 bits. (Fix sysctl(8)

- Remove comments that don't contribute to understanding.
- Remove additional blank lines in output added to maximize compatibility
with older vmstat output, but that is actually somewhat gratuitous.
