Also added a pynfs --minorversion option, committed to

	git://linux-nfs.org/~bfields/pynfs.git master

So, for example, I can run:

	./nfs4.1/testserver.py pip1:/exports/xfs/tmp2 --maketree --rundeps --minorversion=2 --hidepass all

and verify (after the above commit) that all tests pass (except two
known to also fail on 4.1, EID50 and LKPP1d).

--b.

    4.1 server tests: support other minor versions
    
    So you can run tests with minor version 4.2, for example, by using
    --minorversion=2.
    
    This is a bit primitive.  Eventually we'll need it to vary behavior and
    applicable tests based on minorversion.
    
    Also, it shouldn't really allow --minorversion=0.
