Completely rewrite the interface to smbdev switching from dev_clone
to cdevpriv(9). This commit changes the semantic of mount_smbfs
in userland as well, which now passes file descriptor in order to
to mount a specific filesystem istance.

- Remove reset of vpp pointer in some places as long as it's not really
useful and has the side effect of obfuscating the code a bit.
- Remove spurious references to simple_lock.

- Do not put in the mntqueue half-constructed vnodes.
- Change the code so that it relies on vfs_hash rather than on a
home-made hashtable.
- There's no need to inline fnv_32_buf().

Remove MALLOC_DECLAREs of nonexisting malloc-pools.

After careful grepping, it seems none of these pools can be found in our
source tree. They are not in use, nor are they defined.

This update changes the mnt_flag field in the mount structure from
32 bits to 64 bits and eliminates the unused mnt_xflag field. The
existing mnt_flag field is completely out of bits, so this update
gives us room to expand. Note that the f_flags field in the statfs
structure is already 64 bits, so the expanded mnt_flag field can
be exported without having to make any changes in the statfs structure.

Convert to nmount. Add omount compat.

Unpropagate the sm_args function into the runtime part.

Explicitly pass vnode to smbfs_doio() function.

Revert removal of vnode and VFS stubs; bp asserts that they are needed.

Garbage-collect stub vnode ops, use the defaults instead.

Keep trying to flush the vnode list for the mount while some are still
busy and we are making progress towards making them not busy. This is
needed because smbfs vnodes reference their parent directory but may
appear after their parent in the mount's vnode list; one pass over the
list is not sufficient in this case.

This stops attempts to unmount idle smbfs mounts failing with EBUSY.

Implement additional SMB calls to allow proper update of file size as some
file servers fail to do it in the right way.

New NFLUSHWIRE flag marks pending flush request(s).

NB: not all cases covered by this commit.
