84131e0cfc Connections API: executeSqlWithNames, return column names 
This is mainly useful for Python, this way we can probably
avoid calling fields() and all related cost when all we need
is colum names for display.

I'm not very happy with the method name and I would probably just
drop the old signature for executeSql and replace it with the new
one, unfortunately is public API.

But if everybody is happy we could consider an API break.

7388e67bd0 Allow disabling QgsNetworkAccessManager timeout functionality 
by setting the timout to 0

This can be interesting to overcome the limitations of the timeout
functionality by replacing it with QNetworkAccessManager::setTransferTimeout.
E.g. to have more than 6 downloads running in parallel.

1963ef9784 [pointclouds] Add an elevation tab in layer properties, and allow 
users to set a manual offset to apply to point cloud z values

This allows for adjustment of the elevation of point clouds, eg so that:
1. They match nicely with point clouds from other datasources
2. Users can use point clouds from sources with arbitrary z values,
eg. a point cloud made by opendronemap without any actual reference
z values available

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
