Move KREAD define to kvm_private.h

All operation on live kernels uses sysctl interface, there is no reason to
access the swap area. Change kvm_open() to no longer require a swap area,
and to not consider failure to open() it as fatal.

would need an image of the swap area at the time of the crash, anyway.

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

Make context switching much more MI:
- Move the functionality of choosing a process from cpu_switch into
a much simpler function: cpu_switchto. Instead of having the locore
code walk the run queues, let the MI code choose the process we
want to run and only implement the context switching itself in MD
code.
- Let MD context switching run without worrying about spls or locks.
- Instead of having the idle loop implemented with special contexts
in MD code, implement one idle proc for each cpu. make the idle
loop MI with MD hooks.
- Change the proc lists from the old style vax queues to TAILQs.
- Change the sleep queue from vax queues to TAILQs. This makes
wakeup() go from O(n^2) to O(n)

there will be some MD fallout, but it will be fixed shortly.
There's also a few cleanups to be done after this.

Bring back Mickey's UVM anon change. Testing by thib@, beck@ and
ckuethe@ for a while. Okay beck@, "it is good timing" deraadt@.

hide struct process from userland, allow kvm_proc to see it.
okay miod@

move p_limit and p_cred into struct process
leave macros behind for now to keep the commit small
ok art beck miod pedro

Sync with struct proc change.

us did not see it or get a chance to test it before it was commited. It

from netbsd: make anons dynamically allocated from pool.
this results in lesse kva waste due to static preallocation of those
for every phys page and also every swap page.
tested by beck krw miod

careful cleanup following advice from lint. be very very very careful
with sprinkling in size_t!

Use queue macros instead of directly accessing fields. ok millert@

Back out part of last commit; we want to realloc + loop for argv too.

Allocate 8 pages for process argv, not one. This should really be ARG_MAX
but sysctl_proc_args() needs changes to support that.

knf; ok millert

Zero p_schedflags in struct struct kinfo_proc2 for the non-sysctl case.

temporary tree building workaround until millert shows up

Sync PTRTOINT64 w/ kernel version and remove some unused vars.

Implement kvm_getproc2(), kvm_getargv2() and kvm_getenvv2() that use
the KERN_PROC2 sysctl. Based on changes from NetBSD but uses our
own kvm_arg_sysctl().

Zero nlist array before using; fixes a bug in the error condition
when the corefile is not a valid executable. otto@ OK

Remove some double semicolons (hmm, do two semis equal a maxi?).
I've skipped the GNU stuff for now. From Patrick Latifi.

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

Redo the logic in kvm_arg_sysctl for resizing the buffer.
- actually use the value we've just reallocated.
- Don't return success just because the error wasn't ENOMEM (doh!).

If possible get arg and env information with sysctl.
