1. use p = uio->uio_procp consistently and eliminate suspicious uses
...
of curproc (where uio->uio_procp should be used?). Don't do this
for nfs_commit(), because yamt says it is possibly wrong.
2. nfs_doio() does not use struct proc; remove it and the code to compute it.
3. use copyin_proc() and copyout_proc() instead of copyin() and copyout().
4. check return of copyout_proc(). and mark return from copyin_proc() XXX
5. Eliminate check p == curproc assertion check from nfs_write;
nfs_read does not have it and we might be called in a different
process context anyway (PR 20138).

adjust the UBC mapping code to support non-vnode uvm_objects.

this means we can no longer look at the vnode size to determine how many
pages to request in a fault, which is good since for NFS the size can change
out from under us on the server anyway. there's also a new flag UBC_UNMAP
for ubc_release(), so that the file system code can make the decision about
whether to cache mappings for files being used as executables.

remember which credential worked in per-file basis and try it first
next time to minimize number of retries.
