06c4b07222 [processing] Use layer crs/fields instead of provider crs/fields
Since the layer has more complete knowledge of the crs (ie, when
provider could not determine crs and user has selected it from
the list), and also better knowledge of layer fields (virtual
fields, joined fields) we should use these rather than the
provider methods.

bb79d13e82 Remove deprecated Qgis::WKBType and API cleanup (#3325)
* 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

bd7d913379 Refine QgsFeature geometry getters/setters
All pointer based methods have been removed.

Now we have only:

  void setGeometry( const QgsGeometry& geom )

and

  QgsGeometry geometry() const

Benefits include avoiding a whole lot of tricky pointer lifetime
issues, potential memory leaks, and finally closing #777, which
has survived for over 9 years!...

Impacts on PyQGIS code:
- no more need for the messy
  g = QgsGeometry( feature.geometry() )
  workaround, just use g = feature.geometry() instead
- IMPORTANT: you can no longer test whether a feature has geometry
 using `if f.geometry():`, since QgsFeature::geometry() will
 *always* return an object. Instead, use
 `if not f.geometry().isEmpty():`, or preferably the new method
 `if not f.hasGeometry():`

Fix #777
