We could mark the cold path with __attribute__((cold)) (since GCC 4.3),
but quick tests locally indicate that the compiler is smart enough to
determine that by itself.
It will inline the hot path in _q_futex, which in turn is inlined in the
lockInternal and unlockInternal functions, whereas the cold path is kept
outside.

Unlocking a mutex can never throw an exception. That doesn't make
sense and our code should make sure it can't happen. Right now,
provided that the system-level functions don't throw, we don't either.
Locking a mutex cannot throw on Linux because we use futexes
directly. A non-recursive mutex is just a futex, whereas a recursive
mutex uses a mutex (a futex) to manage a lock count.
However, on other platforms, due to the freelist, there can be memory
allocation, which means it might throw std::bad_alloc. Not because of
the freelist itself (that uses malloc and will just crash if malloc
fails) but because of Q_GLOBAL_STATIC. In 5.1, the global static will
be noexcept provided the type's constructor is so too (it is, in this
case).

This will ask the D-Bus library to free its caches. It's useful for
running valgrind on a D-Bus based application, so we can detect real

We can't run this by default because there could be other users of
libdbus-1. Calling the shutdown function would make them stop working.

There's a comment saying nanosleep's availability is questionable, but
the information of what systems don't have that is now lost in
time. It's quite likely that they were older, Unix systems we no
longer support anyway.
nanosleep comes from POSIX.1b-1993, which is merged into POSIX.1-2001,
so chances are that it's supported almost everywhere where Qt runs
(except for Windows anyway).

This would allow implementations to create an optimized way to create
sibling indexes.
A typical pattern of QAIM implementation is to use the same internalPointer
for each row of a subtable of a model (such that the internalPointer is
related to the common parent of each set of rows) and differentiate on the
row value in the QModelIndex. Alternatively, it is also common to have the
internalPointer correspond directly to the row value for the QModelIndex.
In both cases it is possible for the implementation to optimally create a
sibling QModelIndex in the same column as a known row. Provide a virtual
method for them to do so.

Commit 6e6b74c0 introduced heap allocation in the form of
QString::fromLatin1().utf16() into qEmergencyOut(), a function
that's called in OOM situations and in cases where another
exception is still in flight.
Luckily, QString::fromLatin1().utf16() is just a funny way of
copying an array of chars into an array of wchar_ts, so we do
that manually now and use a static wchar_t buffer. While at it,
also throw text elision into the mix.
This commit also fixes the message passed to _CrtDbgReportW().
What should be displayed is the emergency_buf, not the format
string.
Also remove a similar allocation in qt_message_output().
