Fix by returning a default-constructed hash in that case.

The code obtained an iterator into a QHash under mutex protection,
then dropped the lock, dereferenced the iterator several times and
only retook the lock to erase the element from the QHash.
This is very smelly. QHash provides no official iterator validity
guarantees, and the container isn't const, either (which would imply
thread-safety). In particular, the dereference into the container
outside the critical section is cause for concerns.
Simplify the code, removing any doubts about its race-freedom, by
taking the payload item out of the hash before dropping the lock, and
using only the local strong reference in the remainder of the
function.
The only other references to g_pendingPermissionRequests are
insertions with unique-by-construction keys in QtAndroidPrivate's
requestPermissions(), so there was no reason to keep the item in the
hash for the whole duration of the sendRequestPermissionsResult()
call.

QThreadPool maintains three containers of QThreadPoolThread*:
- allThreads, a QSet
- waitingThreads, a QQueue
- expiredThreads, also a QQueue
None of the operations on allThreads make use of QSets fast lookup.
The only functions called on it are isEmpty(), count(), insert(),
and swap().
Since therefore QSet adds nothing but overhead, causes indeterminism
(e.g. when deleting threads in Private::reset()) and code bloat, use
the same container for allThreads that underlies QQueue: QList.
Port insert() to append(). Add an assert to verify that we're not
running into an ABA problem here (but this should never fire, since
we're never deleting threads except in Private::reset(), where we
do remove them from allThreads), just in case.

When a non-QString-backed mode (via the (QChar*, int) ctor) was added
for Qt 4.5, the author forgot to adjust the setCaseSensitivity()
function. It still uses q_pattern instead of (p.uc, p.len) as the
pattern for which to create the skip-table. Since there is no
setPattern() overload for this mode, the correctness of the matcher is
not harmed by this, but its performance degrades to that of a linear
scan: the skip-table, being filled from an empty pattern, will be
all-zeros, sending bm_find() into the 'possible match' case at every
character.
Since matching is still correct, but slow, it's not possible to write
a test for this. I did, however, leave my attempts in the auto-test,
for when we add QStringView overloads of setPattern() which will then
be able to expose the bug.

Since the class is already exported, users of these classes are

Gcc defines neither _MIPS_ARCH_MIPS32 nor __mips32 on MIPS32
architectures, instead __mips is defined to 32.
This fix exposed bit-rot in qdrawhelper where qt_memfill32 was set as
a function pointer despite not being one since Qt4.

[ChangeLog][QtCore][QFileSelector] Removed the requirement for an unused
default base file in case you want to load only a variant.
When the base file (e.g. /image.jpg) was missing, no selectors were
considered and it was not possible to load variants of this file (e.g.
/+android/image.jpg, /+android/+tablet/image.jpg) without specifying the
directory as well.
As a work around, one previously had to place a default file in
the base location, which is undesirable in some cases because:
1. The extra file consumes unnecessary space.
2. It is impossible to encapsulate platform-specific implementation
details by hiding files in a subdirectory.

This is a version of QByteArrayMatcher that calculates the
Boyer-Moore skip table at compile-time instead of at run-time,
making this class more generally applicable than QByteArray-
Matcher itself, at least for statically-known strings.
The compile-time part requires C++14 constexpr support, but
the class should compile and work even in C++98 mode, just
with runtime initialization of the skip-table.
While touching tst_qbytearraymatcher, clean up the static
global QByteArrayMatchers there and add tests with needles
longer than 255 characters for QByteArrayMatcher, too.
[ChangeLog][QtCore] Added QStaticByteArrayMatcher.

QHostAddress is one of the few classes in Qt which is pimpl'd but not
implictly shared, making it suprisingly expensive to copy around, return
by value and so on. Being pimpl'd it is also still lacking a move
constructor, like most of such types in Qt.
Remove a bit of the surprise factor and make it implictly shared. In
practice this means making it eagerly parse host addresses from strings.
Since it was entirely implemented out of line, replacing it with a
implictly shared implementation is binary compatible.
[ChangeLog][QtNetwork][QHostAddress] QHostAddress is now implicitly
shared.

C++17 adopts P0021R1[1], which makes noexcept be part of the function
pointer's type and thus be overloadable. It contains some provisions for
allowing a noexcept function pointer to cast implicitly to a non-
noexcept function pointer, but that fails in the presence of templates
and additional overloads that could match the type in question.
Fortunately, the paper proposed a test macro, so we can change our
sources now and be compatible with both C++14 and C++17 rules.
This first failed with Clang 4.0 trunk. This source incompatibility is
not our fault, it's the language's doing.

This avoids so many complications. The prior code, using
SystemTimeToTzSpecificLocalTime(), lead to unhelpful results when the
QDateTime() implementation used MS-POSIX's defective mktime().
Although SystemTimeToTzSpecificLocalTime() is actually more correct,
we were getting inconsistent results by mixing the two: and
eliminating the use of mktime() turns out to be decidedly tricky. So,
to avoid inconsistency, stick with a UTC time (which is what FILETIME
is defined as). Change QFileInfo's methods to explicitly convert
.toLocalTime() where appropriate and document that these methods do
indeed return local time (as we conjecture has been taken for granted
by callers).
Also added a regression test for the reported case of this going
wrong. A time-stamp from before Russia's (permanent, not DST) change
of TZ could end up inconsistently handled between file-system
meta-data and raw date-time APIs, due to cross-talk between different
MS-Win time APIs.
[ChangeLog][QtCore][QFileInfo] Made sure that all file lifecycle times
are in local time. This was probably true before, but is now explicit.
