PR/7143: Jaromir Docelek: Add procfs/cmdline from Linux emulation

Modify vfsops to seperate vfs_fhtovp() into two routines. vfs_fhtovp() now
...
only handles the file handle to vnode conversion, and a new call,
vfs_checkexp(), performs the export verification.

Machine independent part of fix for PR 6152 (gdb doesn't work on machines
...
with UVM and seperate I&D-Cache). Mostly by Michael Hitch, but pass struct
proc * instead of the pmap. Reason: said machine will need a method to do
the syncing operation for "curproc", too; this way more code can be shared.

Rework the way kernel include files are installed. In the new method,
...
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

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

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

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...
