Changing Q_LOCATION_EXPORT to Q_LOCATION_PRIVATE_EXPORT in all
_p headers to avoid confusion.

This change moves QGeoTiledMappingManagerEngine::CacheAreas to the more
appropriate container that is QAbstractGeoTileCache, which already
uses this enum in its interface.
Together with making the virtual init() method of QAbstractGeoTileCache
public, instead of protected, this patch effectively disentangle
QAbstractGeoTileCache/QGeoFileTileCache from the
QGeoTiledMappingManagerEngine, and makes it usable potentially also
by other (tile) renderers.

This patch adds support for separate caching mode for each of the
three caches, disk, memory and texture.
It also adds separate plugin parameters to the mapbox plugin to
control the functioning of each of these cache.
By default it only sets the disk cache to unitary, to comply with
mapbox TOS, and leaves the other two caches to bytesize behavior
(old beavior).

This patch adds support for unitary pricing of tiles in the disk, memory
and texture caches.
This is done through a new enum in QAbstractGeoTileCache, "CostStrategy"
having two values, Unitary (new one) and ByteSize (the old way).
Using Unitary instead of ByteSize gives, as advantages:
- the ability to comply with the TOS of certain providers, who allow to
cache a fixed number of tiles, and not of bytes.
- even performance with different types of tiles, like lo vs hi res,
indexed vs satellite (which usually compresses much less).
This patch sets the Unitary mode to be the default for the mapbox plugin
since Mapbox is one of the providers whose TOS limit the amount of
cacheable tiles.
Therefore, the patch also modifies the mapbox plugin ".mapping.cache"
parameters to reflect the new behavior.
Since these parameters have been introduced with 5.8 (which is
unreleased), the change doesn't need to be backward compatible.

This patch changes the base cache directory to a new scheme containing
the qt version. At the time of commit, this would be
"QtLocation/5.8/tiles/"
This versioning does not have to change at every release, but when there
are changes in the caching scheme.
The reason for this is that, otherwise, it becomes difficult to clean
up old cache data.
QGeoFileTileCache::init already clean up old tile cache from 5.4 or
older, where the cache data wasn't organized under a directory for
each plugin.
In 5.8 different naming scheme are introduced for mapbox tiles
(with @1x,@2x) , here maps (with ppi), and soon for OSM too (with an
identifier for the actual provider, not only the mapId).
With this patch it will become easier and cleaner to upgrade the
cache data without leaving residues.

Currently the qgeofiletilecache/qgeofiletilecachemapbox contains a bug
in that it makes use of virtual functions in the constructor.
This patch fixes it by moving those calls into a virtual init()
method that is called by QGeoTiledMappingManagerEngine::setTileCache()

This update adds a new method "setTileCache" to the
QGeoTiledMappingManagerEngine class. The method allows custom
map implementations to set their own cache.
The update also fixes a compiler warning (ctor variable order) and
adds Q_DECL_OVERRIDE checks.

The QGeoTileCache is split into two classes:
The abstract class QAbstractGeoTileCache offers interfaces for inserting
and getting tiles, as well as getting cache status information such as
used texture memory.
The new class QGeoFileTileCache implements QAbstractGeoTileCache and offers
a file based caching implementation (the implementation is the same
as before splitting the class).
