Temporarily introduce a new VOP_SPECSTRATEGY operation while I try
to sort out disk-io from file-io in the vm/buffer/filesystem space.

The intent is to sort VOP_STRATEGY calls into those which operate
on "real" vnodes and those which operate on VCHR vnodes. For
the latter kind, the call will be changed to VOP_SPECSTRATEGY,
possibly conditionally for those places where dual-use happens.

Add a default VOP_SPECSTRATEGY method which will call the normal
VOP_STRATEGY. First time it is called it will print debugging
information. This will only happen if a normal vnode is passed
to VOP_SPECSTRATEGY by mistake.

Add a real VOP_SPECSTRATEGY in specfs, which does what VOP_STRATEGY
does on a VCHR vnode today.

Add a new VOP_STRATEGY method in specfs to catch instances where
the conversion to VOP_SPECSTRATEGY has not yet happened. Handle
the request just like we always did, but first time called print
debugging information.

Apart up to two instances of console messages per boot, this amounts
to a glorified no-op commit.

If you get any of the messages on your console I would very much
like a copy of them mailed to phk@freebsd.org

v_tag is now const char * and should only be used for debugging.

Additionally:
1. All users of VT_NTS now check vfsconf->vf_type VFCF_NETWORK
2. The user of VT_PROCFS now checks for the new flag VV_PROCDEP, which
is propagated by pseudofs to all child vnodes if the fs sets PFS_PROCDEP.

Quick fix for non-unique inode numbers for hard links. We use the
byte offset of the directory entry for the inode number for all types
of files except directories, although this breaks hard links for
non-directories even if it doesn't cause overflow. Just ignore this
broken inode number for stat() and readdir() and return a less broken
one (the block offset of the file), so that applications normally can't
see the brokenness.

This leaves at least the following brokenness:
- extra inodes, vnodes and caching for hard links.
- various overflow bugs. cd9660 supports 64-bit block numbers, but we
silently ignore the top 32 bits in isonum_733() and then drop another
10 bits for our broken inode numbers. We may also have sign extension
bugs from storing 32-bit extents in ints and longs even if ints are
32-bits. These bugs affect DVDs. mkisofs apparently limits them
by writing directory entries first.

Inode numbers were broken mainly in 4.4BSD-Lite2. FreeBSD-1.1.5 seems
to have a correct implementation modulo the overflow bugs. We need
to look up directory entries from inodes for symlinks only. FreeBSD-1.1.5
use separate fields (iso_parent_extent, iso_parent) to point to the
directory entry. 4.4BSD-Lite doesn't have these, and abuses i_ino to
point to the directory entry. Correct pointers are impossible for
hard links, but symlinks can't be hard links.
