a83319a075 Add QgsVectorDataProvider::Capability::ReloadData and return it for appropriate providers 
This allows to only show reload actions for data providers that actually support it.

0ab761c210 Add proper method to determine whether a symbol uses map unit sizes, 
and use this to determine whether a legend item needs updating
as a result of a map change

This results in a HUGE speed up when loading large projects where
symbols don't use Millimeter based sizes, as the previous code
assumed only that any non-millimeter size was a map unit based size.

da51a5a8d0 It's FAR too expensive to construct a QgsSettings object for every symbol node, especially for complex 
projects. So only read the valid size ranges once, and store them for subsequent use

4d9bc5bac3 Move responsibility for determining whether a map renderer job requires 
flattening onto a temporary image to the QgsMapLayerRenderer subclasses

This avoids the generic QgsMapRendererJob class from having hardcoded
layer type dependent behavior, and instead moves that layer-type specific
logic to the subclasses designed for that particular layer

def587fa77 [pointclouds] Add an extent only 2d renderer for point clouds 
Useful when you just want an overview of the bounds of the layer in a
2d map. Also potentially usable as a temporary renderer for las/laz
files while we build the indexed representation of the file in the
background.

9aa281abb4 Server: skip initial style storage 
Background: at project load time for all layers a copy of the style
is loaded and stored as a DOM document. This was implemented for
broken layers to make it possible to store the style back to the
project if a broken layer was kept in the project.

Of course this is not needed nor useful in a server context.

By introducing a new project load flag and using it in the server
config (projects) cache we allow to skip the initial storage of
styles for the server and cut the startup times of our test "monster"
project (~1000 PG layers) from 26 seconds to 15.

Before you ask: I chose to always store the original style
with the idea that we might have been able to use the original
style copy also to "restore" styles to their initial state.
This was never implemented, so I guess we might be good to
make the initial style copy selectively available for broken
layers only in order to speed up project loading in the general
case (desktop).
