allocated to the maximum size. Previously, if top was started without
per-CPU stats it would allocate a smaller lcpustates[] array. When
per-CPU stats were then enabled, it would overflow the array and trash
the cpustates_columns[] array causing the CPU stats to be printed in the
wrong locations.

* Fix the sigconv.awk script to generate a header with initializers
which look better.
* Add rules to usr.bin/top/Makefile that rebuilds a new sigconv.h
header which matches the correct signal set from the build-time
version of `${DESTDIR}/usr/include/signal.h' (so sigconv.h doesn't
get stale once changes are made to the header).
* Remove the old sigconv.h header, now that it is autoupdated at
build time.
* Various Makefile style fixes (the committed Makefile was kindly
submitted by Ruslan):
- Reorder .PATH, PROG, SRCS and CFLAGS to match style.Makefile(5)
- Split off the generated sources (sigdesc.h top.local.h) in an
SRCS+= line of their own.
- Add entries to CLEANFILES near the rules that generate the
respective files.
- Move the explicit rule which builds top.1 after the implicit
rules which generate its dependencies.
