f2d04d9b8c eglfs: Make QEglFSWindow respect the window format
Prior to this change, eglfs code used to override the window format
with it's own format. With this change, eglfs will respect the window
format. This is useful when the application requires a surface with
alpha (for example, so that the video layer below is visible)

QEglFSHooks::surfaceFormatFor() allows the hook author to override
the context and window surface format.

a85d15259c Fix QListView::scrollTo() when there are hidden rows
This is a cherry-pick of b0601630dd0ddabfaa3b97d042ee02b981d95988
from February

QListView does not consider hidden rows when scrolling to an item.
If there are hidden rows (or columns) before the selected item then
the visual index of an item is not the same as the row index
from the model. So scrolling will be off by the number of hidden
rows before the selected item.

Added a autotest for this also.

46e40214cf choke uploadProgress signals
The QNetworkReply::uploadProgress signal is intended for updating UI
elements such as a progress bar.
Limit the signal emissions to 10 per second to prevent overloading
the UI with updates.
As with the downloadProgress choke, this is implemented by dropping
signals that occur within 100ms of the previous emission.

The 100% signal is always emitted (bytesSent == bytesTotal)
When the upload size is initially unknown, this behaviour is still
provided by the upload device emitting a suitable readProgress
signal when EOF is reached.

d6d9c8bf32 choke downloadProgress signals
The QNetworkReply::downloadProgress signal is intended for updating
user interface components (e.g. a progress bar).
Limit signal emissions to 10 times per second, with an additional
signal just before the finished() signal to provide the 100% progress.

For the size of download where a progress bar is necessary, this
update frequency seems sufficient.

The implementation is done by dropping signals which would be emitted
less than 100ms after the previous signal emission.

The outdated ScriptsInitial.txt and ScriptsCorrections.txt file has been removed

0346d605e3 Do not add debug/release to QMAKE_CONFIG. Let module system enable them
This solved QTBUG-26111 in which qtjsbackend gets built with an
incomplete framework on Mac OSX. This was traced back to commit
6a6fd56e66 which moved QMAKE_CONFIG
values from .qmake.cache to mkspecs/qmodule.pri. Since qtjsbackend
contains config tests it creates its own .qmake.cache which was
previously masking this issue.

QMAKE_CONFIG incorrectly contained debug for debug_and_release builds
even though debug and release are already present in the CONFIG variable
in mkspecs/qconfig.pri. The changes to configure prevent CONFIG in
qmodule.pri from containing debug and release variables and ensure
that QT_CONFIG contains build_all and debug_and_release if appropriate.
Configure.app is also adjusted to match this behaviour.

The other part of the change is to qt_module_config.prf and
qt_plugin.prf. These changes take care of populating CONFIG with
the appropriate debug_and_release and build_all variables depending
upon what is present in QT_CONFIG. This ensures that the Qt modules
and plugins get built with the same configuration as qtbase.

The special handling for the qcocoa QPA plugin ensures that it is
built in release mode only to preserve the behaviour introduced by
commit 5603f94eaa.

5230d62feb Partial fix for WebKit compilation on Windows
qdatetime.h uses std::min/max and on Windows windows.h (or some subsequent
header file) may under certain circumstances define min/max as macros.

The easiest way to prevent the windows header files from doing that is to
define NOMINMAX in the place right before windows.h is included. The other
way is to define min and max to min/max themselves to prevent windows.h
from doing its evil thing.

If a user of Qt (WebKit in this case) chooses the approach of defining
min/max to themselves and then includes qdatetime.h, then a subsequent
inclusion of windows.h doesn't work because qdatetime.h undefines min/max.

We should not enforce the type of workaround needed, therefore this patch
removes the workaround from qdatetime.h and requires user code that
happens to include windows header files before qdatetime.h (seldom case)
to choose either workaround.

set the deleter to remove the safety check.

Therefore, keep everything in one function.

086d6e74d2 Now merge the QtShared::ExternalRefCount class into QSharedPointer
Completing the work of the previous commit: we don't need separate
classes. Merge into the main class's body.

32edd16e2b Merge QtSharedPointer::Basic into QtSharedPointer::ExternalRefCount
The basic class existed for legacy only, when internal reference
counting was a goal. Since it isn't anymore, we can remove the
distinction and simply merge the two classes.

f77d2e0319 Merge two internal classes of QSharedPointer and de-virtualise them
The two classes are QtSharedPointer::ExternalRefCountData and
ExternalRefCountWithDestroyFn. The split existed because of what Qt
4.5 did before custom deleters existed: the ExternalRefCountData class
was a virtual class that contained a destroy() virtual, which was in
charge of deleting the data or returning false if it didn't.

Turns out that virtual classes was a mistake. This commit
de-virtualises them -- we couldn't do it in Qt 4 because of binary
compatibility. This saves us one pointer-size in the size of the
private, plus the fact that fewer symbols are required (there is no
virtual table to be initialised).

Additionaly, since a deleter is always stored with the reference
count, we don't need the split between the two classes anymore.

55c6f09b3a Remove "delete value" from QSharedPointer
This allows a QSharedPointer to be used in contexts where the class in
question is still forward-declared. This produced a warning in Qt 4 due
to the expansion of the template, even if there was no chance of the
pointer being deleted there (because the reference count could not drop
to zero).

Now, not only is the warning removed, but you can actually have the
reference count drop to zero in a forward-declared class and it will
do the right thing. That's because the deleter function is always
recorded from the point of construction and we're sure that it wasn't
forward-declared.

The unit test for forward-declarations had to be rewritten. The
previous version was passing only because the QSharedPointer object
was created under the "tracking pointers" mode, which causes a custom
deleter to be used in all cases.
