549e2a0bd4 CMake: Make it possible to specify a debug MySQL client
library
If pkg-config is not used, a debug build of the MySQL client library
can be specified with -DMySQL_LIBRARY_DEBUG=. The debug
and release variants of the library are automatically detected. Setting
MySQL_ROOT and MySQL_LIBRARY_DIR is sufficient in most cases.
15045fa8a9 windows: Fix vertical metrics with GDI engine
Fixed an issue where the line gap of some fonts would be included twice
in the font's leading.
3310946227 SQLite: Update SQLite to v3.40.0

Fixed a bug where certain QNetworkRequest::KnownHeaders wouldn't be
recognized as such in certain locales.
2d7753a723 QTest::WatchDog: fix missing timeout resets on test
function change
Fixed a bug which caused QTEST_FUNCTION_TIMEOUT to be applied to the
whole test execution, as opposed to each test function.
b5164f0fdf SQLite: Update SQLite to v3.40.1
Updated SQLite to v3.40.1
14b6eb6e7d Move QTypeInfo from qpair.h to qtypeinfo.h to
avoid ODR violation
The QTypeInfo for std::pair/QPair will now be correct even if qpair.h
hasn't been included, fixing an One-Definition-Rule (ODR) violation.
5ed684e79e QStringConverter: use the QUtf8 codec when Windows is using
UTF-8
Fixed support for using Qt applications with UTF-8 as the system
codepage or by enabling that in the application's manifest.
4768b58f09 Update bundled libjpeg-turbo to version 2.1.5
libjpeg-turbo was updated to version 2.1.5
c581474dfb QVarLengthArray: clear() is not resize(0)
clear() no longer requires the value_type to be default-constructible.
16407d12e7 Text: fix Soft hyphen rendering in QTextLayout::glyphRuns()
Fixed an issue where spaces would sometimes be shown in soft hyphen
positions in a string.
5d208fc91b qstrncpy: NUL-terminate even when src is nullptr
Now NUL-terminates the target buffer even when the source pointer is
nullptr, provided the target buffer has space for at least one byte.
d98e9d29ed CMake: Fix position independent code linker flags not being
set
Qt tools are now built with position independent code even with Unix
toolchains where this is not the default, for example clang.
dfa04903c6 SQLite: Update SQLite to v3.41.0
Updated SQLite to v3.41.0
82dacd839b QFSFileEngine: fix overflow bug when using lseek64

size was bigger than INT_MAX.
34765aae27 SQLite: Update SQLite to v3.41.1
Updated SQLite to v3.41.1

qtdeclarative

361d4bdf54 QQuickNinePatchImage: fix aliasing by respecting the smooth
property
The Imagine style now supports smooth scaling for 9-patch images when
the QT_QUICK_CONTROLS_IMAGINE_SMOOTH environment variable is set to 1.
413b4d1dc1 Fix missing glyphs when using NativeRendering
Fixed an issue where text using NativeRendering would sometimes be
missing glyphs.
d015bb83ea QtQml: Fix coercion of undefined to float and double
Converting a JavaScript value to a double or float now always assumes
JavaScript type coercion semantics. In particular, converting a value
that is not actually a number now results in NaN where it previously
sometimes resulted in 0.

qtconnectivity

934e804b SDP scanner: encode input URLs and escape XML-specific
characters
sdpscanner now %-encodes the URLs and escapes all XML-specific
characters in them before adding the result to the generated XML output.

Fixed a possible crash when editing a field in an item view.
