1fea20de50 Split handling of literal default values from provider side 
default value SQL clauses

QgsVectorDataProvider now has two methods:

- defaultValueClause: returns SQL fragment which must be evaluated
by the provider to obtain the default value, eg sequence values
- defaultValue: returns the literal constant default value
for a field

Avoid saving config parameters that are not set and support not
having them in the XML.

8acc286b0f [FEATURE] Snap to layer algorithm accepts a mode parameter 
With a new option to prefer to snap to closest point on geometry.
The old behaviour was to prefer to snap to nodes, even if a node
was further from the input geometry than a segment. The new option
allows you to snap geometries to the closest point, regardless
of whether it's a node or segment.

f65e770242 [FEATURE[processing] New algorithm to compute geometry by expression 
This algorithm updates existing geometries (or creates new
geometries) for input features by use of a QGIS expression. This
allows complex geometry modifications which can utilise all the
flexibility of the QGIS expression engine to manipulate and create
geometries for output features.

3f2a7810cf Respect non-enforced constraints when editing/adding features 
Warnings are shown, but features can be committed. Fields which
fail an unenforced constraint are now shaded in yellow to differentiate
from the red failure for enforced constraints.

fac5bc0691 [FEATURE] Field constraints can be enforced or not 
Non-enforced constraints just show a warning to the user, but
do not prevent committing the feature. Enforced constraints
block users from comitting non compliant features.

Any constraints detected by the provider are always
enforced.

a6319a47d7 If the layer is NOT being edited then only check layer based constraints 
and not any constraints enforced by the provider

Because:

1. we want to keep browsing features nice and responsive. It's nice to give
 feedback as to whether the value checks out, but not if it's too slow to
 do so. Some constraints (eg unique) can be expensive to test. A user can
 freely remove a layer-based constraint if it proves to be too slow to
 test, but they are unlikely to have any control over provider-side
 constraints

2. the provider has already accepted the value, so presumably it doesn't
 violate the constraint and there's no point rechecking!

exists within a layer's attributes.
