Implement the kernel part of pr-1891. This allows for a more flexible sized
...
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

Move procfs_checkioperm() from procvs_subr.c to procfs_mem.c, since _subr is
...
not included in a kernel without procfs, and it seems wrong to pull
all of procfs_subr.c in for just that one function. Perhaps this
should go into a new file instead?

Fix the procfs hole described on current-users, similar to a fix for
...
FreeBSD by Sean Eric Fagan, but a bit different. This makes the checks
in the same places as sef's FreeBSD patch, but does not hardcode the
"kmem" group into the kernel, and also does a check identical to the
(3) and (4) checks in the NetBSD ptrace(2):
(1) it's not owned by you, or is set-id on exec (unless
you're root), or
(2) it's init, which controls the security level of the
entire system, and the system was not compiled with
permanently insecure mode turned on.

Change the second and third args to struct vfsops' (*vfs_mount)() to
...
'const char *', and 'void *', respectively. The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions. The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...
