process. We don't *quite* pull that number out of our backside, as
the actual number is difficult to determine without modifying the VM
system to report it, but it's still useful to get an idea of what's

The contrib/top code is no longer maintained upstream (last pulled 16 years
ago). The K&R-style followed by the code spews -Wimplicit-int and -Wreturn-type
warnings, amongst others. This silences 131 warnings with as little modification
as possible by adding necessary return types, definitions, headers, and header
guards, and missing header includes.
The 5 warnings that remain are due to undeclared ncurses references. I didn't
include curses.h and term.h because there are several local functions and macros
that conflict with those definitions.

not system processes are displayed) to preserve existing behavior. The
system idle process can be hidden via the '-z' command line argument or the
'z' key while top is running. When it is hidden, top more closely matches
the behavior of FreeBSD <= 4.x where idle time was not accounted to any
process.

This saves 6 more columns in 80-column terminals, making things a lot
better for the COMMAND column.

thread-aware version of errno which is required for a thread-safe libc.
