[Libguestfs] [PATCH 1/2] options: Fixes and enhancements to --key parsing.

[Richard W.M. Jones]

The first patch fixes a rather serious bug, the second patch allows
multiple --key parameters and default parameters.

There is a third patch to libguestfs which adds a test, coming up.

I did not yet review and fix the documentation.  I think we need to
centralize it in one place because at the moment the same
documentation for --key is copy/pasted all over the tools.
