c214c000cc qEnvironmentVariableIntValue: fix the case of a non-numeric value
The documentation says that it's equivalent to
    qgetenv(varName).toInt()

But the implementation wasn't. QByteArray::toInt() verifies that the
entire string was consumed, so QByteArray("1a").toInt() == 0, but
qstrtoll alone doesn't. That is, qstrtoll("1a", ...) == 1.

The implementation also detected the base, a behavior I kept. Instead, I
updated the documentation.

cab9bc8fba Eliminate ambiguous casts involving qfloat16
The operator double() and operator long double() members of qfloat16
are causing cast ambiguities.  This removes them, leaving only
operator float() which seems to be adequate.

Also, additional arithmetic operator tests were added which without
this removal fail to compile.

3ab7016632 New qfloat16 class
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.

6255cb893d Remove qtypetraits.h's contents altogether
So that QFlags can use an (un)signed int matching the
underlying type as identified by the compiler and not by us.

Requires fixing a few warnings about sign conversion due to
QFlags misusages in qtbase that were either plain wrong, or
were relying on the enum being backed by an (un)signed int
when it wasn't.

Keep qtypetraits.h in the source tree in order to prevent
source breaks if some downstream #includes it (note however
that it did not contain any public API).

b2173b54ef Long live QTest::addRow()!
This new function does the same as newRow(), except that it has a less confusing
name (in line with _add_Column()), and accepts printf-style arguments to avoid
the need to newRow(qPrintable(QString::asprintf())), a common pattern in client
code. It uses qvsnprintf() under the hoods, avoiding the need for the QString
const char* round-trip.

Port all in-tree users of newRow(qPrintable(QString::asnprintf())) to the new
function.

ed7f77071d Replace custom type traits with std one's
Remove most type traits from qtypetraits.h, but keep the custom
implementation of is_signed/is_unsigned. This gets rid of
BSD-3 licensed code from Google in a public header (hugh!).

The custom implementations for is_signed/is_unsigned are kept
because the implementations in gcc's standard headers do not
work as we expect for enums - both is_signed and is_unsigned
always returns false there - see also
  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59027

705d29585b Fix qSetMessagePattern to have many time/backtrace parts

%{time}%{time process}%{time boot} ended up to be output as if

This fix keeps the arguments of each individual 'time' part.

The same holds for multiple 'backtrace' parts. The previouse
implementation overwrote multiple 'backtrace' arguments with the
arguments of the last occurrence.

This fix keeps the individual arguments for the 'process' parts.

The individual arguments are applied in qFormatLogMessage.

5ff7a3d96e Add {add,sub,mul}_overflow for signed integers.
In C++, signed overflow math is Undefined Behavior. However, many CPUs
do implement some way to check for overflow. Some compilers expose
intrinsics to use this functionality. If the no intrinsic is exposed,
overflow checking can be done by widening the result type and "manually"
checking for overflow. Or, for X86, by using inline assembly to use the
CPU features.

Used in QtQml.

a2b58c1643 Implement qt_is_{inf,nan,finite} using std. library functions.
The previous implementations did not check the full mantissa. The result
was that certain NaN values were seen as +/-Infinity.

A nice benefit is that the generated code for this implementation is also
faster.

29bc68cf16 Add code to perform overflow-checking additions and multiplication
Most processors have carry flags which they set on addition overflow, so
it's a good idea to access them whenever possible. Most of them also
have widening multiply instructions that can be used to detect overflow
of the non-widening version.

Tested to compile on:
 Architecture     Compiler
  x86             GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta
  x86-64          GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta
  x86-64 ILP32    GCC 4.9, GCC 5*, Clang 3.6*
  IA-64 LP64      GCC 4.8
  ARMv7-A         GCC 4.9, Clang 3.6*
  AArch64         Clang 3.6*
  MIPS            GCC 4.9, Clang 3.6*
  MIPS64          GCC 4.9, Clang 3.6*
  PowerPC         GCC 4.9, Clang 3.6*
  PowerPC 64      GCC 4.9, Clang 3.6*
  SPARC           Clang 3.6*
  SPARCv9         Clang 3.6*

[*] supports the intrinsics

If the compiler does not offer a way to detect an overflow, we do it by
hand. For unsigned additions, that's easy, since the C++ language
specifies the behavior of the overflow. That's also the reason why this
code is implemented only for unsigned integers.

For the multiplication, if the compiler does not support widening
multiplications, we do it with a division instead. This is necessary for
GCC < 4.5 and compilers not compatible with GCC or MSVC.

7b0e771ad7 Add a qtHookData field for Qt Creator's data display
Qt Creator needs to be able to determine structure sizes and data
member offsets for certain private types even in the absence of debug
information.

It is sufficient to keep and test the actual data sets on the Qt Creator
side, as long library provides a hint which data set is needed.
So far, HookDataVersion was meant to be used for that purpose. To
make it more explicit, this patch introduce a TypeInformationVersion
field in qtHookData.
