44e7f3371e [FEATURE] New algorithm for creating vector layer from raster layer's extent 
Allows creation of a new vector layer with a single feature containing
a raster layer's extent. Previously this was only possible for
vector layers.

51f8b1a2bb Port Convert Geometry Type to new API 
Includes partial support for Z/M types (values are lost during
conversion, but at least 2d geometries are exported)

TODO: full support for Z/M/curves

cfb926a70d Port Find Projection alg to new API 
Also modify alg to export a vector table of candidates instead of
a HTML list, since a vector table is more useful inside of
models and can be used for further analysis steps.

required for compatibility with a database destination, etc)

ea06500caf Port Unique Values algorithm to new API 
Improvements:
- by default output a table with unique values, instead of a HTML
file. This allows the values to be more easily used in follow up
analysis (e.g. in a model). HTML output is still available, but
not output by default

b7f888bf5b Port Distance Matrix algorithm to new API 
Enhancements:
- support source/target layers in different CRS
- output layers with geometry (i.e. keep input point geometry - avoids
need to rejoin result back to original table to get geometry)
- keep original data types for id fields
- don't fire off many single feature requests - instead request
multiple features at once to improve speed

11475c621d Revert "Merge pull request #4562 from alexbruy/processing-singletomulti-3" 
This reverts commit e3d79a1fe940b5d813b5f79c51b43393d085bb16, reversing
changes made to 3f7f95ee262ea3646d61600c21faed0866bc70b0.

Reverting again, as Travis started failing after merging PR (with all
test passed) into master branch
