[attributetable] Fix "Move selection to top": for 2.18 regression fixes qgis#15803

fix bugs related to statistical dock (fix qgis#16117, qgis#16118, qgis#16119)

If a transform exception occurred while rendering a symbol then
the QgsSymbolRenderContext cleanup code was never called,
leading to a double delete and crash.

Fixes qgis#16377, qgis#15345, and numerous other crashes seen "in the wild"

[processing] handle NULL values in the single to multi algorithm (fix qgis#15822)

Fixes qgis#15507

Includes automated test.

R scripts in processing only supports Vector, Raster and Table.
This commit adds fix the file output and adds directory, number and string outputs.

This follows the convention used by OpenLayers, where
an inverted axis is indicated by {-y} in the URL
definition.

Followup bfa507a

Default values for attributes on the linking table have not been
respected and therefore it was impossible to create entries on the
linking table with the combination of NOT NULL + default value.

... also when collapsing and uncollapsing a relation editor.

References qgis#15102 (https://issues.qgis.org/issues/15102)

Avoids unpredictable behavior when transforms are being conducted
in background threads, such as map renders.

Refs qgis#11441

This commit:
1. Uses QThreadStorage for projCtx objects, to ensure that every
thread correctly has its own projCtx context

2. Refactors QgsCoordinateTransform so that the projPJ source and
destination objects are instead stored in a map (by projCtx). This
allows transforms to be transparently performed using the correct
projPJ objects for the particular thread in which the transform is
being conducted. This approach allows a single QgsCoordinateTransform
to be safely utilised in different threads.

Don't advise for rows added when a model reset is in progress.
Otherwise the rows are tested for sort order, etc triggering
a bunch of useless calculations, given that the model is in
the process of being reset anyway.

Tested using a 150k point shapefile, decreased attribute table
load times from 50+ seconds to 4 seconds.

Drops load time for table from 100 seconds to 50 seconds for a
