This constitutes a fairly complete submission of an entirely new
floating point type which conforms to IEEE 754 as a 16-bit storage
class. Conversion between qfloat16 and float is currently performed
through a sequence of lookup tables. Global-level functions
qRound(), qRound64(), qFuzzyCompare(), qFuzzyIsNull(), and
qIsNull() each with a qfloat16 parameter have been included
for completeness.
[ChangeLog][QtCore] Added new qfloat16 class.

These hooks only worked reliably with LD_PRELOAD on Linux/GCC, on other
platforms they depended on what exactly the compiler optimizer is doing
as well as some nasty assembler rewriting to actually access them. The
new system uses a simple array of function pointers that can be set to
custom hooks by tools that need this (based on ideas from Andre Poenitz).
This also covers qt_startup_hook (similar problem), and the Qt version
number that Andre had asked for.

Lack of support for these types is not a real issue as endian
conversions on byte-sized types are no-ops. Still, the conversions are
useful as they facilitate writing of generic code. They can also be used
explicitly as a way to document in code an endian-specific binary
format:
uchar *data;
quint8 tag = qFromLittleEndian<quint8>(data++);
quint32 size = qFromLittleEndian<quint32>(data);
This commit also adds a test for functions documented in the QtEndian
header.

Check the QT_OUTPUT_PATTERN environment variable in the default
message handler to customize the output of messages. Following
place holders are right now supported:
%{message}, %{type}, %{file}, %{line}, %{function}
The original cleanupFuncinfo was written by Thiago Macieira.

Record the file, line, and function where a qDebug, qWarning, qCritical
or qFatal call happens, and make this information available in a custom
message handler.
The patch uses the C preprocessor to replace qDebug, qWarning, ... with
a line that also records the current file, line, and function. Custom
message handlers can access this information via a new QMessageLogContext
argument.
