MAXCOMLEN is no longer needed in these programs, so remove the annotation
from sys/param.h include lines, or remove the include lines entirely if
it this was the least requirement.

A few fixes for kvm_getargv(3)/kvm_getenv(3):

1. Most notable: this splits argv buffer into argv-specific one
and environ-specific one. This makes ps -eww totally happy.

2. realloc() usage

and environ-specific one. This makes ps -eww totally happy.

2. realloc() usage in kvm_argv() is now ENOMEM-prone.

3. The "int off" changed to "ptrdiff_t off", as it should be.

Make amaps use less kernel memory (2nd try)

The original diff would crash at least i386 and powerpc, as spotted by
guenther@ The reason was an incorrect use of sizeof in amap_lookups().

Make amaps use less kernel memory (2nd try)

The original diff would crash at least i386 and powerpc, as spotted by
guenther@ The reason was an incorrect use of sizeof in amap_lookups().

Confirmation that powerpc works by mpi@ and mglocker@

"throw it in" deraadt@

Original commit message:

This is achieved by grouping amap slots into chunks that are allocated
on-demand by pool(9). Endless "fltamapcopy" loops because of kmem
shortage should be solved now. The kmem savings are also important to later
enable vmm(4) to use larged shared memory mappings for guest VM RAM.

This adapts libkvm also because the amap structure layout has changed.

Reimplement uvm/uvm_map.

vmmap is designed to perform address space randomized allocations,
without letting fragmentation of the address space go through the roof.

Some highlights:
- kernel address space randomization
- proper implementation of guardpages
- roughly 10% system time reduction during kernel build

Tested by alot of people on tech@ and developers.

Correct the links between threads, processes, pgrps, and sessions,
so that the process-level stuff is to/from struct process and not

at c2k10.

Reimplement kvm_getproc2()'s support for reading crash dumps and
/dev/mem to be direct instead of going through kvm_getprocs(), as
that function is going to get more an more broken as we move stuff
from struct proc to struct process for rthreads. To minimize the
code copying, put the common logic of filling in a kinfo_proc2
structure into a macro FILL_KPROC2() in <sys/sysctl.h> for use from
both the kernel and user-space. This also hides the KERN_PROC
#define behind "#if defined(_KERNEL)||defined(_LIBKVM)", as it's
deprecated.

Positive feedback from millert and blambert; so committing to unblock
further rthreads work.
