4d60d0cdb5 [FEATURE] Add option to QgsGeometry::smooth to not smooth 
segments shorter than a certain threshold or sharp corners
with an angle exceeding a threshold

Expose the angle threshold to processing smooth algorithm

Also:
- optimise QgsGeometry::smooth for new geometry classes
- Fix smooth does not work with geometries containing Z/M

56b77db88c [FEATURE][processing] Add choice of simplification method to simplify 
This change allows users to choose which method to use when running
the simplify geometries algorithm, with choices of the existing
distance based (Douglas Peucker) algorithm, area based (Visvalingam)
algorithm and snap-to-grid.

Visvaligam in particular usually results in more cartographically
pleasing simplification over the standard distance based methods.

71ebdb8f69 [FEATURE] Optimise processing clip algorithm 
Before the algorithm was written to optimise clipping a few
features against thousands of mask features. The revised algorithm
is optimised for clipping thousands of input features against
a few mask features.

Given that this second operation is much more likely, it makes
sense to optimise for this use case.

I've also applied some other optimisations like taking advantage
of spatial indexes on the providers, using prepared geometries
and also only applying an intersection operation if the geometry
isn't wholly contained by the mask geometry.

Benchmarks:

clipping roads layer with 1 million lines against 2 polygons

before: 5 mins 30 seconds
after: 10 seconds

clipping address layer with 5 million points against 2 polygons

before: 50 minutes
after: 30 seconds

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.
