8c855e05d7 Handle v_writecount from union_open(), union_close() and union_revoke()

90ead62d2f Change the protocol to update a mounted file system from read-write 
to read-only and vice versa:

- Add an internal flag IMNT_WANTRDONLY.
- Set either IMNT_WANTRDWR or IMNT_WANTRDONLY if going from or to read-only.
- After successfull call to VFS_MOUNT() set or clear MNT_RDONLY.

Adapt tmpfs and rumpfs to the new protocol.  Other file systems will be
updated when they get the IMNT_CAN_RWTORO property.

be48413a3c Be explicit about how we're placing part of the on-disk name into 
the extension, so it doesn't appear like we are overrunning an array.

b5981bcf46 In the event that loading the root vnode fails, bail out of 
tmpfs_mount instead of crashing.

Came up in PR 51436, where kmem issues caused internal allocations to
wrongly fail. However, that could happen for real sometime (e.g.
probably if you tried to mount a new tmpfs when the system was very
low on memory, or possibly for other reasons entirely) and crashing
isn't the ticket.

(This is not a fix for PR 51436)

- tmpfs_node_get: restore (decrement) the node count on the error path.
- tmpfs_bytes_max: save the value of uvmexp.freetarg (since it is
  unlocked/racy).

d938d837b3 Introduce m_set_rcvif and m_reset_rcvif 
The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.

42866dd28d Cleanup VAT writout. To prevent issues with the sequential writing strategy 
trying to write on blocks that are lost due to the synchronisation, don't just
bluntly do synchronize device caches, but split out on strategies.

46e9cd4dbd Rework VAT searching on recordable media. It is now a lot more resilliant to

the question who is responsible for syncing pending writes, but the
