We've seen crashes with QThreadPrivate::start using qgetenv during the creation
of the event dispatcher, while another thread (for example the gui thread)
called qputenv. This is inherently thread-unsafe and there are many places
where we make the assumption that using the environment is safe. However access
to the environment is inherently unsafe in the C runtime and the best that we
can do is add a mutex around the Qt environment access functions, to at least
protect ourselves and our users.

In certain situations, when reading a large amount of data from
sequential devices with QIODevice::readAll(), content was lost when
passing a qint64 value > QByteArray::MaxSize into QByteArray::resize(),
which takes an int. The result of the conversion to int is either negative or
calculated mod 2^32. In any case, it will at some point be < QByteArray::size(),
which prompts QByteArray to truncate, losing already-read content.
Fix by adding an explicit size check before calling QByteArray::resize().
This shows once more that an API that uses int for sizes is dangerous.
Esp. on 64-bit platforms.

This patch fixes several upload corruptions if the server closes the connection
while/before we send data into it. They happen inside multiple places in the HTTP
layer and are explained in the comments.
Corruptions are:
* The upload byte device has an in-flight signal with pending upload data, if
it gets reset (because server closes the connection) then the re-send of the
request was sometimes taking this stale in-flight pending upload data.
* Because some signals were DirectConnection and some were QueuedConnection, there
was a chance that a direct signal overtakes a queued signal. The state machine
then sent data down the socket which was buffered there (and sent later) although
it did not match the current state of the state machine when it was actually sent.
* A socket was seen as being able to have requests sent even though it was not
encrypted yet. This relates to the previous corruption where data is stored inside
the socket's buffer and then sent later.
The included auto test produces all fixed corruptions, I detected no regressions
via the other tests.
This code also adds a bit of sanity checking to protect from possible further
problems.

After selecting all (enabled) transitions for a microstep, filter out
any conflicting transition. The actual conflict resulution is done by
ordering the transitions in order of the states that selected them.
For example: if an event would trigger two transitions in a parallel
state where one would exit that state and the other would not, this
filtering prevents the state machine from selecting both states (as this
case is an invalid state of the whole machine).
This also fixes the exit set calculation for parallel states when one of
its substates is exited and subsequently re-entered in the same
transition. Previously, the parallel state was not exited, and
subsequent re-entry was ignored (because it was still active). Now it is
correctly exited and re-entered.
A side-effect of the transition ordering mentioned above is it also
fixes the non-deterministic behavior of which of the conflicting
transitions is taken.

The more conditionally-noexcept functions are used, the more important it
becomes that low-level classes are correctly marked noexcept. In that, it

change).
It also is inconsistent with the const char* overloads of these methods,
which explicitly preserve nullness (as verified by test cases).
Fixed by an explicit check for nullness and return of null QString.
Alternative would have been to check for nullness and pass nullptr
instead of ba.data() to the _helper() functions, which do the correct
thing in that case. But since we'd have the check anyway and with the
chosen strategy we can avoid a call to a non-inline method, I opted
against that.

Make use of the Linux implementation for Hurd as well, as the mntent API

Since PATH_MAX is not available on Hurd, and the current bufferSize is
a lot more larger than it is needed, restrict bufferSize to 1024 bytes,
which should be enough to cover 3 paths in mtab and it is usually used
also in other projects.

This change does not add any infrastructure to enable more advanced

Normally when maximizing a window it will cover the available geometry
of the screen, as represented by QScreen::availableGeometry(), which
typically excludes status/menu bars and application launchers.
On some platforms it may still be possible to place windows in the areas
of the screen that are outside of the available geometry, but this will
result in the window being partially covered by (possibly) transparent
system UIs. The new flag allows the user to specify that when maximizing
the window it should try to cover as much as possible of the screen
geometry (in contrast to going full screen, which would typically
hide any system UIs).
For iOS this is a common use-case, as the status bar is transparent,
and the user-interface guidelines for iOS7 and up recommend taking
advantage of the full screen space, while keeping any user-interaction
elements still inside the available geometry of the screen.

The function getDateFromJulianDay() is simple arithmetic, but still
~400 bytes in executable size.
Yet GCC inlines this everywhere I looked, which makes some sense,
as different users of the class only use parts of the return
value and the optimizer has a field day removing all that dead
code.
However, that function has only one conditional, so presumably it
executes at full pipeline speed and it doesn't matter that it
calculates too much in some cases. More important is to use the
I-cache more conservatively.
That's what not inlining the function achieves.
The function returns its result in registers and doesn't spill
registers when called (at least on AMD64), so the effect on
runtime should be negligible.
