Cleanup QgsDataProvider #95

Open nyalldawson opened 5 years ago

nyalldawson commented 5 years ago

QgsDataProvider has a lot of legacy cruft, which is unused and no longer belongs in QgsDataProvider. Eg.

setLayerOrder and setSubLayerVisibility -- unused
fileVectorFilters and fileRasterFilters -- unused and replaced with methods inside QgsProviderRegistry
subLayerCount - unused
subLayerStyles - unused
description - unused

Removing these would also result in cleanups to QgsMapLayer and subclasses, as these proxy some of the unused data provider methods.
