nfs: Redesign fop argument passing to support single volfile use

The current design of the interaction between the generic NFS layer and the
protocol handlers like mount3 and nfs3 is such that it does not allow using a
single volume file which contains the nfs/server and the protocol/server.
This is because the common nfs-fops layer assumes that ctx->top is always the
nfs/server. This is wrong. The fops layer needs access to top because top or
rather the generic NFS xlator's private state has a mem-pool. The fops layer
needs this mem-pool to get memory for storing per-fop state. Since the fops
layer cannot anymore take ctx->top be the nfs/server, all layers need to start
passing the nfs/server xlator_t right down to the fops layer.

I am also taking this chance to remove the synchronous equivalents of the fops
and also remove the dirent caching directory operations.
