Adds label distance factor spinbox to Point Displacement symbology
window. Calculates label distance based on the current symbology
diagonal instead of a general maximum diagonal.
Replaces the hard coded distance "symbolDiagonal/2.0" with
"symbolDiagonal*mLabelDistanceFactor", where mLabelDistanceFactor is set
to the spinbox value.
It's an old feature request (Point displacement labels adjustable
offsets "https://issues.qgis.org/issues/5945").
Partly reverts c9e761649, which removed the synchronizatiion of
credential requests (eg. in a project that has multiple layers from the
same postgresql database without credentials) and led to multiple
concurrent requests for the same credentials.
Some of which were silently discarded, when events processed in the
dialogs exec() event loop tried to reinvoke the dialog and caused
invalid layers.
Authentications caused by network requests can still cause this.
The credential cache is now guarded by a separate mutex.

Turns out there is NO reliable way to create a proxy model
which adds new rows to a model, so just bite the bullet and
do it in the underlying model (yuck)
[feature] [mesh] #20731 add option to format time in mesh layer
There is new settings dialog that can be opened by button next to time slider. User can set reference time and time format (e.g. 2019-03-21 22:01:11).
This adds a new parameter type specifically for map scales,
QgsProcessingParameterScale. The values are evaluated using
self.parameterAsDouble, which returns the map scale
denominator (matching the standard in other parts of the
QGIS API).
Scale parameters are displayed to users using the standard
QgsScaleWidget, which includes the combo box of predefined
scales and a shortcut button to match the current map scale.
Returns a descriptive list of the possible string values acceptable
for the parameter.
E.g. for a QgsProcessingParameterVectorLayer this may include
"Path to a vector layer", for QgsProcessingParameterBoolean
"1 for true, 0 for false" etc.
