648840c617 QMimeDatabase: handle removal of a mime directory
The previous commit didn't handle correctly the case where an entire
mime directory is deleted. The unittest wasn't testing that case,
now it is. We need to move providers into a new list, and then
delete those left over (i.e. now unused).

7a5644d648 QMimeDatabase: redesign to use both binary and XML providers
Previously, we would use mime.cache in all mime directories if at
least one of them had such a file (other than the most-local one),
otherwise the "source" XML would be used in all directories.

Now it's possible to use mime.cache in those directories which
have one, and XML in those directories that don't.

Not only is this more correct, it will allow in a subsequent
commit to bundle the binary cache in QtCore's qrc rather than
the very big XML file.

The design change to allow this is that now every provider
only deals with a single directory, and QMimeDatabasePrivate
takes care of creating multiple providers, one for each dir.
This required to move most of the loops from the binary provider
up to QMimeDatabasePrivate itself.

8835c0376b QMimeDatabase: move recheck test up from the mime providers
This is actually simpler (two calls to ensureLoaded are enough,
rather than one in every implementation method) and is necessary
for further refactoring steps (which will instanciate more provider
instances).

2c062546a2 macOS: Fix handling of multiple ampersands in menu items
If the text of a QAction in a menu item contained a sequence of multiple
ampersand characters, only one of them would be removed, which is
inconsistent with the way this situation is handled on Windows, where
every other ampersand is removed, which is also the way other widgets
such as tabs, buttons, etc. are handled on macOS and other platforms.

a09fc184ac Add a configure-time check for QT_COMPILER_SUPPORTS_SIMD_ALWAYS
This has two main benefits:
 1) introduces a qmake CONFIG we can use in .pro/.pri/.prf files
 2) removes the need to keep an up-to-date list of which compilers
    support the feature

The test is implemented as trying to compile every single SIMD test we
currently have, but without passing the -mXXX option. The reason for
trying all of them is that some people may have modified their mkspecs
to add -mXXX options or -march=XXX, which could enable the particular
feature we tried, resulting in a false positive outcome.

ff1ffa7577 Add support for AVX-512 intrinsics found in MSVC 2017 15.3
It seems the compiler supports /arch:AVX512 and /arch:AVX512F but none
of the other switches (and neither are documented). And when you pass
those, you also get Conflict Detection (CD), Double & Quad (DQ), Byte &
Word (BW) and Vector Length (VL), which matches the ICC switch
"-xCORE-AVX512". Unlike ICC, there doesn't seem to be an option to
enable only the common part of AVX-512.

Support for Intel Xeon Phi's current features (Exponential &
Reciprocation and Prefetch) and future ones (IFMA, VBMI, 4FMAPS, 4VNNI
and VPOPCNTDQ) seems to be missing altogether.

See https://blogs.msdn.microsoft.com/vcblog/2017/07/11/microsoft-visual-studio-2017-supports-intel-avx-512/

f984c45373 QStorageInfo: use Linux's /proc/self/mountinfo to get the subvolume
This allows us to get "subvolumes" on all filesystem types. We do that
by detecting the subdirectory that was bind-mounted.

/proc/self/mountinfo has been in the kernel since 2.6.26. Since btrfs
was only added on 2.6.29, there is no loss of functionality for btrfs
users.

I've tested this with subvolume or mountpoint names containing spaces,
tabs and newlines.

4d0add31fd Add QNetworkRequest::ResourceTypeAttribute for use in QtWebKit
Often requested feature in QtWebKit is reporting what kind of resource
corresponds to particular QNetworkRequest, similarly to
QWebEngineUrlRequestInfo::resourceType(). This information can be used
to modify or block certain request types in user's implementation of
QNAM::createRequest().

The only clean way to pass this data is via attributes of QNetworkRequest,
so enum value needs to be reserved. It's unlikely to be used anywhere
outside of QtWebKit, however this is already the case for
SynchronousRequestAttribute.

prefer it over /etc/timezone (which is no longer needed since

This fixes a wrongly reported local timezone when a stale /etc/timezone

eade2255ea Windows: Resolve QStandardPaths config location without qApp instance
Calling QCoreApplication::applicationDirPath() requires an app instance,
but on Windows the implementation just relies on qAppFileName(), which
does not require any instance. As resolving the standard paths could
be needed before QCoreApplication instantiation, e.g. for categorized
logging, we use qAppFileName() directly.

fb2e795c6e iOS: Take UIWindow bounds into account when making window fullscreen
When an app is in split-view mode, the app can't use the full bounds of
the screen, but should limit its area to that of its UIWindow.

a6d7f38791 QHeaderView: Simplify and fix layoutChange handling
A layoutChange indicates that anything can have moved to anywhere else,
including as a result purely of new items being added. It can also
indicate that items are removed.

The old code here incorrectly assumed that the section count remained
constant over this operation by setting the size of the oldSectionHidden
QBitArray - whose size is the size before the layoutChange operation -
and then calling setBit with model rows numbered after the layoutChange
operation.  As the two are not necessarily the same dimensions, this can
result in asserts from the setBit call.

Simplify the handling of layoutChanged entirely by clearing section
information, and using the QPersistentIndexes which indicate hidden
state to restore that state after re-population.

Fusion style did not honor direction option when drawing the child

d813c66bfc Fix the build when AVX2 is enabled but __F16C__ isn't defined
If -mavx2 is used, __AVX2__ is defined, which enables the F16C code
after commit 280e321e52, but that was
wrong since we aren't allowed to use the F16C intrinsics with either
Clang or GCC (we can only do that with GCC 4.9 and Clang 4.8, and only
with an __attribute__ decoration).

With ICC and MSVC, we are allowed to use the intrinsics, but the
#include was missing.

[ChangeLog][QtCore] Fixed a compilation issue with qfloat16 if AVX2
support is enabled in the compiler. Since all processors that support
AVX2 also support F16C, for GCC and Clang it is recommended to either
add -mf16c to your build or to use the corresponding -march= switch.
