elevation related properties to their layers
And use this to ensure that wms tiles with maptiler terrain
or terrarium terrain interpretation are always included by
default in elevation profile plots.
Most specifically, this ensures that projects containing the
out-of-the-box "Mapzen Global Terrain" layer will be automatically
included in elevation plots.

QgsAbstractDatabaseProviderConnection
When implemented by providers, will provide a method for
permanently setting field aliases/comments within a
database
Here we have no choice but to create a new Capability2
enum, as the original Capability has now consumed the
entire range of values for data types permitted by QFlag
Conversion between relative and absolute paths when reading/writing project files
has been inconveniently done in subclasses of QgsMapLayer in encodedSource() and
decodedSource() methods, with a lot of provider specific code.
This is a refactoring to finally fix this - there is a new pair of functions added
to QgsProviderMetadata and QgsProviderRegistry:
- absoluteToRelativeUri()
- relativeToAbsoluteUri()
This new pair of functions delegates the actual conversion between absolute and
relative path to provider code - where it belongs.
The existing code from encodedSource() and decodedSource() functions has been moved
to providers. Unit tests were added to confirm the existing behavior.
There should be no change of behavior apart from removal of old compatibility code
for WMS provider for projects from QGIS < 1.9 (10 years ago).
In most cases of use of QGIS Server, it is not necessary to access the layers in write mode.
The read-only mode is sufficient.
We would like to introduce a new flag Qgis::ProjectReadFlag::ForceLayerReadOnly to
open layers in a read-only mode.
QgsProviderSqlQueryBuilder provides an interface for creation of SQL queries, which
can be overridden for backend provider specific SQL syntax.
Initially add a virtual method for creation of row limited select *
queries.
