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.

Currently QMetaType API contains almost only static methods. This works
nice until someone needs more information or needs to do more operations
on a type. In this case every function call has to do type dispatch.
This API allows to avoid redundant type dispatching, by caching a
type information in a QMetaType instance. It gives significant
performance boost especially for custom types (up to 9x).

Some of Qt's autotests depend on access to a test server. For each test
that used the test server, tests/auto/network-settings.h created a
global object to verify at startup that host lookups to the test server
will succeed (and abort the test otherwise).
There are two problems with that approach:
First, the sanity check happens before main(), and thus before the test
framework has started logging test results. This means that if the
sanity check aborts the test, the failure message will not be visible in
the test output if logging to a file or will cause the output to be
malformed if logging to the console in XML format.
Second, since Qt 4.7, the host lookup uses a class that connects to the
QCoreApplication instance, which doesn't exist before main(), and this
caused all tests that included network-settings.h to output an error
message from QObject::connect() at the beginning of the test.
Both of these problems are solved by removing the global object from
network-settings.h and instead performing the sanity check in the
initTestCase() function of each test.
