Until now we have not honored the min/max zoom levels specified
in QGeoCameraCapabilities when requesting tiles.
As a result we have often fired requests for non-existing tile layers.
This change complements the added support for individual camera caps
for each map type, and makes the tile fetcher honor the bounds
defined in the camera capabilities.
This also allows to set larger zoom levels in the renderer, overzooming
existing tiles, without the fetcher firing requests for invalid
resources

This cache fixes the cache mixing problem that has been introduced
with the osm high dpi tiles support.
high dpi providers fall back to low dpi ones and ultimately
to hardcoded providers (also low dpi), and can also be enabled/disabled
via plugin parameter, thus leaving the cache for a given map id
dirty for the next run.
With this patch high dpi tiles are named differently from low dpi ones.
If high-dpi providers are selected, but become not available, the
cache can also change the tileset to load at runtime

This patch adds a mean to enable/disable high dpi support for the
OSM plugin too, following the same approach taken for the mapbox and
here plugins.
In order to do so, it has been necessary to rework QGeoTileProviderOsm.
It can now be constructed with an arbitrary number of TileProviders,
as opposed to the previous approach with one primary and one fallback
tileprovider.
It has also been necessary to disable Nearest interpolation for high
dpi tiles, as it appears to produce considerable artifacts.
So in presence of highdpi tiles, Linear interpolation is now always
used.

To prevent furter breakage of qtlocation osm provider
in existing qt versions, this patch introduces one
level of indirection in resolving OSM providers, fetching
the tile server address from files hosted at
http://maps-redirect.qt.io/osm/5.6/
The content of the files requested for the server
address resolution must be in JSON format, containing
(currently) the following fields:
{
"Enabled" : bool, (optional)
"UrlTemplate" : "<url template>", (mandatory)
"ImageFormat" : "<image format>", (mandatory)
"MapCopyRight" : "<copyright>", (mandatory)
"DataCopyRight" : "<copyright>", (mandatory)
"MinimumZoomLevel" : <minimumZoomLevel>, (optional)
"MaximumZoomLevel" : <maximumZoomLevel>, (optional)
}
Enabled is optional, and allows us to temporarily disable
tile providers if they go offline without firing requests
to them. Default is true.
MinimumZoomLevel and MaximumZoomLevel are also optional,
and allow us to prevent tile requests to the providers,
if they do not support the specific ZL. Default is 0 and
19, respectively.
<server address template> is required, and is the tile
url template, with %x, %y and %z as placeholders for the
actual parameters.
Example:
http://localhost:8080/maps/%z/%x/%y.png
<image format> is required, and is the format of the tile.
Example:
"png" or "jpg"
<MapCopyRight> is required and is the string that will be
displayed in the "Map (c)" part of the on-screen copyright
notice.
example:
"<a href='http://www.mapquest.com/'>MapQuest</a>"
<DataCopyRight> is required and is the string that will be
displayed in the "Data (c)" part of the on-screen copyright
notice.
example:
"a href=
'http://www.openstreetmap.org/copyright'>OpenStreetMap</a>
contributors"
The patch also adds four additional OSM plugin parameters,
modifies an existing ones, and removes another existing one.
Removed:
- osm.mapping.copyright, now removed and replaced by two
other parameters (see below).
New:
- osm.mapping.providersrepository.address, allowing to change
the hardcoded http://maps-redirect.qt.io/osm/5.6/
The implication of this parameter is that it becomes possible
to use file:// urls or even qrc:, allowing to ship custom
providers with the applicarions
- osm.mapping.providersrepository.disabled, allowing to disable
the indirection and go with hardcoded URLs by default.
- osm.mapping.custom.mapcopyright replaces the old
osm.mapping.copyright, and contains the copyright notice to be
displayed next to the "Map (c)" part of the copyright, to be
consistent with the way the copyright notice coming from the
provider data is handled
- osm.mapping.custom.datacopyright replaces the old
osm.mapping.copyright, and contains the copyright notice to be
displayed next to the "Data (c)" part of the copyright, to be
consistent with the way the copyright notice coming from the
provider data is handled
Modified:
- osm.mapping.host now became osm.mapping.custom.host,
improving the naming consistency.

This enables the usage of various mapping services which use the OSM
API for tile distribution. One only needs to set the urlprefix
parameter to a correct url and the activeMapType to the "Custom URL
Map".

QPointer holds a guarded pointer to a QObject. It must always be tested
prior to use.
Changed the parameter type to remove the need for the static_cast when
setting the QPointer member.
The root cause was that the tile fetcher object was not being destroyed
when the mapping manager engine was. Which was because the two objects
were in different threads. Some of the service specific tile fetchers
were directly calling into the engine objects across thread. Gah.
Since Qt 5 QNAM uses an application global thread for processing
requests, there is no need to use threads in the tile fetcher.
