the function call succeeded. NetBSD 4.0 returns positive values on success, but NetBSD Current and FreeBSD return zero. OpenBSD's man page doesn't tell what sysctl() returns on success. All these BSDs return -1 on error. Thanks to Robert Elz and Thomas Klausner.

the number of CPU cores. Added support for using sysinfo() on Linux systems whose libc lacks appropriate sysconf() support (at least dietlibc). The Autoconf macros were split into separate files, and CPU core count detection was moved from hardware.c to cpucores.h. The core count isn't used for anything real for now, so a problematic part in process.c was commented out.
