ede452be85 [processing] Port feedback object to c++
Algorithms are now passed a QgsProcessingFeedback object
instead of the loosely defined progress parameter.

3550cc99a6 [processing] Allow algorithms to specify tags
Tags are used while searching in the toolbox. This should help with
finding algorithms when the exact name is not known, eg
you could search for "envelope" or "bounds" and find the
'Polygon from Layer Extent' algorithm.

At the moment it's quite hard to discover algorithms which exist
when you don't know what their called and have to instead search
for every possible naming variant which could exist...

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

30fcaed634 [FEATURE][processing] New algorithm for merging connected lines
This algorithm joins all connected parts of MultiLineString
geometries into single LineString geometries.

If any parts of the input MultiLineString geometries are not
connected, the resultant geometry will be a MultiLineString
containing any lines which could be merged and any non-connected
line parts.
