randr: Add provider object support (RandR v1.4)
With RandR 1.4 provider objects have been introduced. "A provider object
represents a GPU or virtual device providing services to the X server."
To handle provider objects the following requests have been added:
- GetProviders
- GetProviderInfo
- SetProviderOffloadSink
- SetProviderOutputSource
- ListProviderProperties
- QueryProviderProperty
- ConfigureProviderProperty
- ChangeProviderProperty
- DeleteProviderProperty
- GetProviderProperty
And the Notify event got 3 new subcodes:
- ProviderChange
- ProviderProperty
- ResourceChange
v2:
- add missing name field to GetProviderInfo
v3:
- changed ProviderCapability enum
o replaced <value> with <bit>
o removed None
- replaced "alignment pad list" with commented out <pad align="4"/> to
be prepared for future enhancements
- add brief description to commit msg about additions
