This change defines the QgsApplication::applicationFullName()
method for use with PostgreSQL application_name
and QGIS Server Logging.
For QGIS Server, the QGIS_SERVER_APPLICATION_NAME
can be specified instead and will take precedence over the QGIS_APPLICATION_FULL_NAME
setting.
The value may also be specified in the /qgis/application_full_name
variable in the QGIS Server config file.
By default, this value will be defined by the value of QgsApplication::applicationName()+' '+QgsApplication::platform()
.
