Useful for GPKG and other database based drivers
- For OGR drivers that have GetFIDColumn() != '', expose it as a QGIS
field.
- When creating features, use the value potentially provided in this
first field, as the feature id to force to OGR. Disallow changing it
in changeAttributeValues()
- show correct domain type as field type name
- correctly determine length and precision of domain types
- expose bpchar field type as 'character' to users, as postgres only
uses 'bpchar' internally and refers to bpchar as character in the
front end
A new "legend" tab has been added to diagram properties, allowing
both the existing attribute legend and a new size legend to be
enabled/disabled. The size legend has a configurable marker
symbol.
Also includes unit tests for both diagram attribute and size
legends.

This change allows the attributes of multiple features to be edited
simultaneously. It is enabled when the attribute table dialog is in
"form mode", via a new "multi edit" button on the toolbar.
In this mode, attribute value changes will apply to all selected
features. New widgets appear next to each editor widget allowing for
display of the current multi-edit state and for rolling back changes
on a field-by-field basis.
Changes are made as a single edit command, so pressing undo will
rollback the attribute changes for all selected features at once.
Multiedit mode is only available for auto generated and drag and
drop forms - it is not supported by custom ui forms.

Bugfix of issue introduced in commit 9040ec1baf33e55a9ba5abcc4fa2ee18d54a4212
When doing the spatialite cache initialization with OGR, the attribute
names get 'laundered' in lower case, which makes their matching afterwards
fail. Fix this. And also handle the situation where an attribute would
be named 'geometry'
GDAL 2.0 changed (fixed) the bilinear downsampling algorithm, so
switch to the average algorithm so that test results are the same
for GDAL versions >= 2.0 and < 2.0.
