b9d0c518f9 When using /dev/ksyms, don't keep it open more than strictly necessary. 
This allows LKM manipulation while an application using libkvm, such as
vmstat or gkrellm, is running.

Patch reviewed by Anders Magnusson.

f08d6eb0c9 Make the kvm routines use /dev/ksyms to get the kernel namelist. 
If it fails, use /netbsd instead.

a9f690ae2a Add kvm interface to the new sysctls: 
kvm_getproc2() -> sysctl(KERN_PROC2)
	kvm_getargv2() -> sysctl(KERN_PROC_ARGS, KERN_PROC_ARGV)
	kvm_getenvv2() -> sysctl(KERN_PROC_ARGS, KERN_PROC_ENV)
Add new KVM_NO_FILES flag to kvm_open*() - set up enough state to
use the above calls without having to open any kernel files.

XXX: kvm_getprocs.3 and kvm_open.3 to be updated soon.

fa72190309 Fix the empty error message problem more completely. When the magic-check 
fails on the cpu_hdr, return 0 instead of -1. This allows the caller to
distinguise between fatal errors and 'nothing there'.

cca068a144 Fix the mysterious empty error message when savecore is executed and no 
dump is present. This was caused by the fact that kvm_dump_mkheader() was
called *before* savecore checks the dump magic and kvm_dump_mkheader() returned
-1 without setting an error message. The latter is fixed now.

9c2128ecdd New libkvm/savecore implementation. With the following differences: 
1) savecore will not access the dump or live-kernel directly. It
        will always use the kvm-functions. Allowing it to work on kernels
        that don't have a 1-1 PA-VA mapping.
     2) the kvm-lib has some additional functions to accomplish 1
          - kvm_dump_mkheader()
          - kvm_dump_wrtheader()
          - kvm_dump_inval()
     3) the file formats of the dump generated by the kernel and the dump
        generated by savecore have been changed. The file format now looks
        like the format produced for 'normal' core dumps.
Ports not yet supporting the new kvm-format will be using libkvm.old/
savecore.old for the time being.
