[Libguestfs] [PATCH nbdkit RFC 0/2] curl: Implement authorization scripts.

[Richard W.M. Jones]

This is an RFC only, at the very least it lacks tests.

This implements a rather complex new feature in nbdkit-curl-plugin
allowing you to specify an external shell script that can be used to
fetch an authorization token for services which requires a token or
cookie for access, especially if that token must be renewed
periodically.  The motivation can be seen in the changes to the docs
in patch 2.
