77486bda39 Get rid of dependency on fs_nfs.h, i.e. source modules with 
conditional content depending on if the NFS client is wanted or
not.  The server can now be made an independent module not depending
on the nfs client.

Tested with rump_nfs (standalone client), rump_nfsd (standalone
nfsd) and a qemu installation with both the client and the server.

5dabc83466 Handle EWOULDBLOCK the same way as EPIPE. It seems the TCP socket layer 
can return EWOULDBLOCK on some occasion when the connection is broken.

65aa3ef107 If send fails with EMSGSIZE for whatever reason, it's unlikely to 
succeed no matter how hard we retry.  So just fail the request.

82357f6d42 ANSIfy another 1261 function definitions. 
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

454af1c0e8 Change about 4500 of the K&R function definitions to ANSI ones. 
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

f41b56aff5 Actually enforce the maximum timeout (60s by default) rather 
than backing off to 256*SRTT.  This is why it sometimes could take
hours for a NFS mount to come back when the server returned.

92ce8c6a3d Make the emulations, exec formats, coredump, NFS, and the NFS server 
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

15e29e981b Merge the socket locking patch: 
- Socket layer becomes MP safe.
- Unix protocols become MP safe.
- Allows protocol processing interrupts to safely block on locks.
- Fixes a number of race conditions.

With much feedback from matt@ and plunky@.

febe85111f - remove nfs_exit exit hook. ok'ed by christos@. 
- as far as i understand the code, it shouldn't be necessary
	  because nfs_request can't return without removing its request
	  and r->r_lwp is either curlwp or NULL.
	- even if it's necessary, leaking requests is not the correct way
	  to recover from the condition.
- nfs_request: add a related assertion.
