Instead of copyign a pre-existing .db shipped with QGIS, create
a new .db and import an .xml file containing our default symbols.
On the UX front, the main benefit is being able to ship with
pre-defined tags and favorite flags for the default symbols.
On the developer side, it means we get rid of the requirement
to maintain both an .xml and a binary .db in the source tree.
We also say aurevoir to the symbol_xml2db.py script and the
need to update the (obsolete) script every time we add a new
feature to QgsStyle.
* Revert "Disable failing PyQgsOfflineEditingWFS test"
This reverts commit 33ee514b5dfdc1b57558cb9007df5b455a59fc17.
* Let lifetime of layers be controlled by QGIS
These may represent additional layers such as layers which
are not included in the map layer registry, or paths to
layers which have not yet been loaded into QGIS.
literal defaults, and qgis expression defaults) and automatically
handle unique value constraints on layers
Add a new method QgsVectorLayerUtils::createFeature which returns
a new feature which includes all relevant defaults. Any fields
with unique value constraints will be guaranteed to have a value
which is unique for the field.
Currently only in use by the split feature tool.

Returns a new unique attribute value for a layer. For numeric
fields this is the max attribute value + 1, for strings we
attempt to create a unique value by append _1, _2, etc to either
a specified 'seed' value, or failing that to the end of the
value of that field from the first feature in the layer.
a substring from a vector data provider
Base implementation iterates through all features, but
providers can override with optimised versions. Native
implementations for postgres, spatialite and OGR included.
- A new favorite grouping system was added, which the symbols list
widget defaults to
- The selected tag / smartgroup in the symbols list widget now
persists when switching layers (and across sessions)
- The symbols list widget will update the tag / smartgroup combo
box when users add / rename / remove categories
- Users can now directly tag, as well as add to favorites, symbols
while saving those to the style database
- To streamline style management, groups have been removed and
fully replaced by tags
- Tags have been integrated into the import/export user interface
Implements a method in QgsGeometry and a processing algorithm to
calculate the pole of inaccessibility for a surface, which is the
most distant internal point from the boundary of the surface. This function
uses the 'polylabel' algorithm (Vladimir Agafonkin, 2016), which is an iterative
approach guaranteed to find the true pole of inaccessibility within a specified
tolerance. More precise tolerances require more iterations and will take longer
to calculate.

Include C++ and Python tests
Travis won: ported all test cases to Python
and disabled C++ companion test (still useful locally and
for debugging)
For the curious: QTemporaryFile is not working as expected
Moved to Qt5 new style signals
Disabled C++ test and connected cancel to progress
Make string comparison on SSL errors more robust
Better solution is to set handlesNull to true to avoid the default
null parameter = null result behaviour, and handle null values
in params 1 and 2 manually
- support negative start value (e.g. substr('hello',-2) returns 'lo')
- support negative length value (e.g. substr('hello',3,-1) returns 'll')
- length parameter now optional, defaults to end of string
(e.g. substr('hello world',7) returns 'world')
