A major sweep over the sysctl stuff. Move a lot of variables home to their own code (In good time before xmas :-) Introduce the string descrition of format. Add a couple more functions to poke into these marvels, while I try to decide what the correct interface should look like. Next is adding vars on the fly, and sysctl looking at them too. Removed a tine bit of defunct and #ifdefed notused code in swapgeneric.

#include <sys/param.h>
#include <sys/systm.h>
Included <sys/sysproto.h> to get central declarations for syscall args structs and prototypes for syscalls. Ifdefed duplicated decentralized declarations of args structs. It's convenient to have this visible but they are hard to maintain. Some are already different from the central declarations. 4.4lite2 puts them in comments in the function headers but I wanted to avoid the large changes for that.

The entire sysctl callback to read/write version. I havn't tested this as much as I'd like to, but the malloc stunt I tried for an interim for sure does worse. Now we can read and write from any kind of address-space, not only user and kernel, using callbacks. This may be over-generalization for now, but it's actually simpler.

This implements enough of the BSDI extensions to the net-2 ogetkerninfo() syscall to allow applications linked against their libc's uname() to work. Netscape 1.1N being a prime example, which prints: "uname() failed. cant tell what system we're running on". This change is a little ugly, but that's mainly because of the "interesting" semantics of the BSDI extension. Since ogetkerninfo() is only enabled by COMPAT_43, Netscape will only be affected on kernels with that option (eg: "GENERIC") Reviewed by: davidg

Included <sys/sysproto.h> to get central declarations for syscall args structs and prototypes for syscalls. Ifdefed duplicated decentralized declarations of args structs. It's convenient to have this visible but they are hard to maintain. Some are already different from the central declarations. 4.4lite2 puts them in comments in the function headers but I wanted to avoid the large changes for that.
