randr: add provider object and provider property support (v6)

This adds the initial provider object and provider property
support to the randr dix code.

v2: destroy provider in screen close
v2.1: fix whitespace

v3: update for latest rev of protocol + renumber after 1.4 tearout.

v4: fix logic issue, thanks Samsagax on irc

v5: keithp's review: fix current_role, fix copyrights, fix master
reporting crtc/outputs.

v6: port to new randr interface, drop all set role bits for now

v7: drop devPrivate in provider, not needed, add BadMatch returns
for NULL SetProviderOffloadSink and SetProviderOutputSource, drop
the old typedef.
