[PATCH] server/xmlrpc: Simlify featureset handling

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Rather than passing featureset around various places where the data doesn't
really belong, run a command at connection time to set the appropriate
features. This is similar to what the process server does.
