* Remove deprecated Qgis::WKBType and API cleanup Renames QgsWKBTypes to QgsWkbTypes Replaces usage of the enums: * Qgis::WKBType with QgsWkbTypes::Type * Qgis::GeometryType with QgsWkbTypes::GeometryType Their values should be forward compatible (a fact that was already explited up to now by casting between the types) Renames some SSLxxx to SslXxx and URIxxx to UriXxx * Fix build warnings and simplify type handling * Add a fixer to rewrite imports * The forgotten rebase conflictThe forgotten rebase conflicts * QgsDataSourcURI > QgsDataSourceUri * QgsWKBTypes > QgsWkbTypes * Qgis.WKBGeom > QgsWkbTypes.Geom * Further python fixes * Guess what... Qgis::wkbDimensions != QgsWkbTypes::wkbDimensions * Fix tests * Python 3 updates * [travis] pull request caching cannot be disabled so at least use it in r/w mode * Fix python3 print in plugins
