d842a96579 Fix incorrect handling of unsigned short values in point cloud providers

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).

f6f03cd8e1 [api] Add z range filtering option to QgsMapSettings/QgsRenderContext/QgsMapCanvas 
Allows for map renders to be filtered by a z or elevation range,
such that only parts of the layer which are considered within
this range will be rendered.

Implements https://github.com/qgis/QGIS-Enhancement-Proposals/issues/201

*Requires support for respecting the QgsRenderContext zRange to be added
to the relevant map layer renderers

83ccb6554e [processing] Add method to set an explicit override for the default 
value of a parameter for the GUI only

This allows us freedom to change the default settings for an algorithm
shown when opening the algorithm in the toolbox/batch/model without
changing the underlying default value used for the parameter in the
raw API (which we can't do easily without potentially breaking 3rd
party scripts/plugins)

Nyall Dawson
483cb8dfb1 Add api to set the maximal extent for a project 
If set, this extent will be used when zooming to full extent (or for the
full extent for a map overview frame) instead of the extent calculated
from all map layers.

The intention is to eventually allow users a way to manually set their
desired "area of interest" for a project, so that zooming to full extent
won't zoom all the way out when the project contains global or national
datasets...
