kvm_getprocs.
basically cope with the number of procs growing between when we get
the size and when we get the list.

might have increased between when we got the number of files and
when we requested that number of files.
now we allocate another 10ish percent on top of what the kernel
says we need, and retry if that still isnt enough.
while here use realloc instead of constantly going through free/malloc
sequences.

- when a socket is closed with fds in its input, defer closing them to
a task to avoid recursing. This eliminates the complicated extra
reference taking which had a 37 line(!) comment explanation
- move flags, counts, and links only needed for this from struct file to
struct unpcb
- document the flow of the mark/sweep collector

lower VM_MIN_KERNEL_ADDRESS, since these systems are not crippled by the
Sun-4 MMU hole and have the real 4GB of address space.
Kernels running on Sun-4 MMU are not affected and will still be restricted
to the existing 128MB of kernel space, with 1GB - 128MB of user space.
Kernels running on SRMMU will now provide the low 3GB of address space to
userland, and use the top 1GB for the kernel, except when compiled with
option SMALL_KERNEL, in which case they will keep Sun-4 style the layout
(this is temporary to allow for people to boot bsd.rd to upgrade even when
not running 2.10 boot blocks, and will be removed eventually)
A consequence of this is that the top of the userland stack is no longer at
0xf0000000. But since nothing in userland uses USRSTACK anymore, this should
not be an issue.
Tested on sun4c and various sun4m, with physical memory sizes ranging from 32
to 448MB.

the extra argument to be zero; instead, make it filter on the file

from 472 to 392 bytes on amd64. When splicing gets active, another
88 bytes are allocated for struct sosplice.

PS_{ZOMBIE,EMBRYO} on the process instead of peeking into the process's
thread data. This eliminates the need for the thread-level SDEAD state.
Change kvm_getprocs() (both the sysctl() and kvm backends) to report the
"most active" scheduler state for the process's threads.

Noone sane will mourn these ports anyway. So long, and thanks for the fish.

- convert netstat from kvm_getfiles() to kvm_getfile2() using that
- delete kvm_getfiles() and KERN_FILE as no longer used (bump libkvm's major)
- rename kvm_getfile2() to kvm_getfiles(), kinfo_file2 to kinfo_file
and KERN_FILE2 to KERN_FILE.

members to 64bit types. Assign new syscall numbers for (almost
all) the syscalls that involve the affected types, including anything
with time_t, timeval, itimerval, timespec, rusage, dirent, stat,
or kevent arguments. Add a d_off member to struct dirent and replace
getdirentries() with getdents(), thus immensely simplifying and
accelerating telldir/seekdir. Build perl with -DBIG_TIME.
Bump the major on every single base library: the compat bits included
here are only good enough to make the transition; the T32 compat
option will be burned as soon as we've reached the new world are
are happy with the snapshots for all architectures.
DANGER: ABI incompatibility. Updating to this kernel requires extra
work or you won't be able to login: install a snapshot instead.
