8da90206bc Make tmpfs_node_t::tn_gen a 32-bit number, keep it in sync with tmpfs_fid_t. 
Also, change tn_status to unsigned while here.

1f5dbc945b tmpfs: replace the broken tmpfs_dircookie() logic which uses the node 
address truncated to 31 bits (required for 32-bit readdir compatibility,
e.g. linux32).  Instead, assign 2^31 range using the following logic:
- The first half of the 2^31 is assigned incrementally (the fast path).
- When exceeded, use the second half of 2^31, but manage with vmem(9).

It will require 2 billion files per-directory to trigger vmem(9) usage.
Also, while here, add some fixes for tmpfs_unmount().

Should fix PR/47739, PR/47480, PR/46088 and PR/41068.
Thanks to wiz@ for stress testing.

f8abe6cb77 tmpfs_alloc_node: it is less error-prone to store the link path with 
the NIL terminator included.  Adjust tmpfs_readlink() to exclude NIL.
Also, remove the check for zero-length and add some asserts.

6ca3558714 Import FreeBSD's "newnfs" nfs client and server code. This contains 
nfsv4 as well as new implementations of nfsv3 and nfsv2.

This import is from tonight's FreeBSD head and is unchanged from there
except for automated munging of rcsids, rearranging of paths, and an
autogenerated files.* file that might or might not be syntactically
valid. (I will check in the script that does this shortly.)

There is not the slightest chance this will configure yet, let alone
compile or run.
