6d50f746fe Support for Q_OS_ANDROID_EMBEDDED and android-embedded build flags
The Embedded Android build (Boot to Qt Android injection) is defined by
having both Q_OS_ANDROID and Q_OS_ANDROID_EMBEDDED flags defined,
as well as having Qt config android-embedded.
This commit enables the possibility to build embedded Android builds.
(i.e. Qt build for Android baselayer only, without JNI)

984ad61249 Improve readability of code that uses the Qt signed size type
During the container BoF session at the Qt Contributor Summit 2017 the
name of the signed size type became a subject of discussion in the
context of readability of code using this type and the intention of
using it for all length, size and count properties throughout the entire
framework in future versions of Qt.

This change proposes qsizetype as new name for qssize_t to emphasize the
readability of code over POSIX compatibility, the former being
potentially more relevant than the latter to the majority of users of
Qt.

19b0ce5daa Change almost all other uses of qrand() to QRandomGenerator
The vast majority is actually switched to QRandomGenerator::bounded(),
which gives a mostly uniform distribution over the [0, bound)
range. There are very few floating point cases left, as many of those
that did use floating point did not need to, after all. (I did leave
some that were too ugly for me to understand)

This commit also found a couple of calls to rand() instead of qrand().

This commit does not include changes to SSL code that continues to use
qrand() (job for someone else):
  src/network/ssl/qsslkey_qt.cpp
  src/network/ssl/qsslsocket_mac.cpp

a55f36211e Fix the JPEG EXIF reader to deal with some broken/corrupt files
We parse the EXIF header in order to get the proper orientation, so
let's be a bit more careful in what we accept. This patch adds better
handling for reading past the end of the stream, plus it limits the
number of IFDs read (to avoid processing too much data) and deals with a
pathological case of the EXIF file format: EXIF (due to its TIFF
origins) permits the offset to the next IFD to be backwards in the file,
which means it could result in a loop or pointing to plain corrupt data.
We disallow any backwards pointers, since it seems that's what other
decoders do (libexif, for example).

b0abe20d4b Darwin: Add QImage::toCGImage() conversion function
(Move QT_FORWARD_DECLARE_CG to qglobal.h)

This function converts to CGImage for supported formats. This
is done by creating a CGImageRef that reuses the QImage data.

The CGImage and QImage ref counting systems are bridged, implemented
by using CGDataProvider that holds a copy of the QImage.

Unlike the previous internal implementation this public version
does not implicitly convert unsupported formats to ARGB32_Premultiplied.

See included documentation for the complete description.

7bf002c3b3 Backwards compatibility fix: No default colormap for Mono QImages
This is a partial revert of a4e2f2e687.

That fix tried to avoid the risk of a crash in pixel() by ensuring
Mono QImages created with external data also got a default color
table. However, that broke usable behavior in existing code that was
painting in Mono QImages using color0/color1.

This commit reverts to the old behavior, and instead expands on the
checking in pixel() so that lacking color table is handled gracefully
for all indexed formats.

QImage::pixel() assumed that the color table was valid
for the values in the bitmap. This was always wrong
for indexed images with explicit no color table set and
was wrong for mono images that were constructed from
preexisting data.

For mono images, we default to a black/white color table,
like we do when constructing with uninitialized data.

For indexed image, we always default to no color table,
but instead of crashing in pixel(), we warn and return
an undefined value.

3859b304e8 tests/auto/gui: Replace Q[TRY]_VERIFY(a == b) by Q[TRY]_COMPARE(a, b).
- Replace Q[TRY]_VERIFY(pointer == 0) by Q[TRY]_VERIFY(!pointer).
- Replace Q[TRY]_VERIFY(smartPointer == 0)  by
          Q[TRY]_VERIFY(smartPointer.isNull()).
- Replace Q[TRY]_VERIFY(a == b) by  Q[TRY]_COMPARE(a, b) and
  add casts where necessary. The values will then be logged
  should a test fail.

8f760808e0 Fix premul conversion from ARGB32 to A2RGB30 formats.
When a premultiplied alpha changes value because it is rounded to fewer
bits the premultiplied colors may need to be recalculated with the new
value. Otherwise the color will both be wrong and potentially invalid.

ba323b04cd Optionally apply orientation on QImage read
Make it possible to read images with EXIF orientation automatically
applied. This was originally implemented without opt-out in Qt 5.4, but
reverted. Here it is implemented as opt-in for JPEG, and opt-out for TIFF
to keep behavioral consistency.

The EXIF support for JPEG was written by Rainer Keller.

[ChangeLog][QtGui][Image plugins] An option has been added to
QImageReader to enable automatic application of EXIF orientation.
This behavior was default in Qt 5.4.1, but reverted in Qt 5.4.2.

041cbe4b38 Add missing RGB32 <-> RGB30 convertions
Completes the inplace converters so that we can rely on inplace
conversions to succede as long as the image depth is the same.

68faf3a9bb Fix QImage format after inplace conversion
Some inplace conversions would not set the requested image format in
the returned image, due to the same conversion being used for several
destination formats.

This patch ensures all inplace conversions return the right format,
and adds testing infrastructure to easily test iterate over all formats
so that they all can be tested.
