This abstraction imposed serious performance penalties and is being
dropped from the public API.
In particular, by allowing file names to be arbitrarily hijacked by
different file engines, and requiring engines to be instantiated in
order to decide, it imposed unnecessary overhead on all file operations.
Another flaw in the design with direct impact on performance is how
engines have no way to provide (or retain) additional information
obtained when querying the filesystem. In many places this has meant
repeated operations on the file system, where useful information is
immediately discarded to be queried again subsequently.
For Qt 4.8 a major refactoring of the code base took place to allow
bypassing the file-engine abstraction in select places, with
considerable performance gains observed. In Qt 5 it is expected we'll be
able to take this further, reaping even more benefits, but the
abstraction has to go.
[Dropping this now does not preclude that virtual file systems make an
appearance in Qt at a later point in Qt 5's lifecycle. Hopefully with a
new and improved abstraction.]
Forward declarations for QFileExtension(Result) were dropped, as the
classes were never used or defined.
Tests using "internalized" classes will only fully run on developer
builds. QFSFileEngine was removed altogether from exception safety test,
as it isn't its intent to test internal API.

Commit 4b8ceb41ae added the requirement
that pointed-to types need to be registered when registering pointer
types. Unfortunately, the implementation also affects function pointer
types.
This change whitelists 0, 1, 2 and 3 argument functions as not deriving
from QObject, forgoing the need to workaround details of the type
registration implementation when registering those function pointer
types.

As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

This is a source incompatible change for Q_DECLARE_METATYPE(T*),
which now requires T to be fully defined.
The consequences of this are:
* Forward declared types can no longer be declared as a metatype.
(though this is a very uncommon thing to do).
There is a trivial workaround where necessary.

Use the C++ boolean constants true and false instead of the C macros
TRUE and FALSE (which are actually integers), and use QVERIFY instead of
QCOMPARE for verifying simple boolean expressions.

Currently there seems to be no precise definition of what
an integrationtest is in the context of Qt testing.
To avoid confusion, the tests under integrationtests/ are
moved into other/ (which is effectively where we keep
tests that don't clearly fit into any other category).
Tests can be moved back into an integrationtests/ directory
at a later point, should an unambiguous definition be established.
