This commit adds a new mode to the attribute table dialog for searching
and filtering features. When activated (using a button on the toolbar
or by pressng CTRL+F), the dialog will switch to form view and all
widgets are replaced with their search widget wrapper variant.
Alongside each widget is a tool button with options for controlling
the search/filter behaviour for that field, eg "equal to", "not equal
to", "is null", "greater than", etc.., with the options presented
matching themselves to the corresponding field and widget type.
New buttons appear at the bottom of the form for either selecting
matching features (with options for add to selection/remove from
selection/select within current selection) or filtering features
in the table (with options for adding features to a current filter
or further restricting a current filter).

Uses new gradient editor widget and color controls for easier
manipulation of gradients. Also adds an interactive plot
for modifying gradient stops via the color HSV or RGB values.

Supports:
- drag to move color stops
- double clicking to add a new stop
- pressing delete will remove the selected stop
- pressing arrow keys will move the selected stop, shift+arrow= larger
move
- drag and drop a color onto the widget to add a new stop

A "filled marker" is similar to the simple marker symbol layer, except
that it uses a fill sub symbol to render the marker. This allows use
of all the existing QGIS fill (and outline) styles for rendering
markers, eg gradient or shapeburst fills.
A new abstract class QgsSimpleMarkerSymbolLayerBase has been created
from which both QgsSimpleMarkerSymbolLayerV2 and
QgsFilledMarkerSymbolLayer derive. All common code has been moved to
this base class, allowing for easy addition of new shapes or features
to both simple markers and filled markers without duplication.
Also, adds a lot of missing docs to marker symbol layers.
The original name was not representative for the scope of the class
and misleading at best.
The class manages actions for a given layer and it's not a single action
like the former name suggested.
There is a typedef introduced to keep it in the API until we can remove
it with QGIS 3.
When enabled, repeating locks are not automatically cleared when
a new point is added. They are handy when the same constraint
must be repeated for multiple points (eg adding vertices
which are always 50 meters apart)
(fix#12605)
constraint is locked
The previous behaviour was that the constraint had to be "relocked"
if the user manually altered the constraint value in the text
widgets. Now users can edit the constraint value after already
locking the constraint.
Usually QObjects must subclass and override methods like focusOutEvent
to handle focus events. Using this class as an event filter avoids
the need to subclass objects and the focus events can be directly
caught using the emitted signals.
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.

and new widget QgsComposerItemComboBox for showing matching composer
items.
Swap existing comboboxes to use the new widget, which removes a lot
of fragile code designed to allow selection of items. Additionally
the combobox now show the correct item id rather than always showing
"Map 0/1/..."
Using this renderer no symbol will be drawn for features, but labeling,
diagrams and other non-symbol parts will still be shown.
Selections can still be made on the layer in the canvas and selected
features will be rendered with a default symbol. Features being edited
will also be shown.
This is intended as a handy shortcut for layers which you only want
to show labels or diagrams for, and avoids the need to render
symbols with totally transparent fill/border to achieve this.
