shared one binary for all backends

Merge commit 'ronnie/master'

Trim off some LOOKUP calls we do not need in the nfs loadfile to initialize
the name->fhandle mapping any more.

Make sure to create the /clients directory if it does not exist

move the loadfiles to a subdir

Merge branch 'ronnie-test'

added newline at EOF

converted all backends to new common format

updated README (sort of)

In child.c : For all commands such as "CreateX,..." check if the backend
supports this command or not.

Create a structure of function pointers to hold all possible operations dbench
can manage.
Add all NFSv3 specific operations to this structure.

Let sockio, nfsio and fileio provide this structure to dbench telling
dbench which command they can handle and which they do not understand.

Add three new commandline parameters specific to nfsbench :
--server  --export and --protocol

add an nfs loadfile

Add nfsbench and libnfs to the makefile

add nfs client library and the dbench nfsio backend

add nfs and mount rpcgen specifications
