Nyall Dawson 5b244ae88c [FEATURE] More geometry functions for expressions
- add accessors: geometry_n, interior_ring_n
- add num_geometries, num_rings, num_interior_rings
- add nodes_to_points for converting every node in a geometry
to a multipoint geometry
- add segments_to_lines for converting every segment in a geometry
to a multiline geometry

nodes_to_points and segments_to_lines are intended for use with
geometry generator symbology, eg to allow use of m and z values
for nodes/lines with data defined symbology.

Updating the srs.db
-------------------

The srs.db can be updated from the EPSG codes in the
GDAL installation:

1) Install latest GDAL, be sure to configure with --with-python.
2) Set PATH and PYTHONDIR if installed GDAL in non-standard location.
3) Run 'scripts/qgis_srs.sh > new_srs.sql'. It may take a minute or two.
4) Run 'sqlite3 new_srs.db < new_srs.sql'.'
4) Run 'sqlite3 new_srs.db <postprocess_srs.sql'

You can use sqlite3 to dump the contents from both srs.db and new_srs.db
before you decide to commit.
