Actually check that there's a T where ISO 8601 wants it (instead of
just skipping over whatever's there), with something after it; move
some declarations later; add some comments; and use the QStringRef API
more cleanly (so that it's easier to see what's going on). Simplify a
loop condition to avoid the need for a post-loop fix-up.
This incidentally prevents an assertion failure (which brought the
mess to my attention) parsing a short string as an ISO date-time; if
there's a T with nothing after it, we won't try to read at index -1 in
the following text. (The actual fail seen had a Z where the T should
have been, with nothing after it.)
Add tests for invalid ISOdate cases that triggered the assertion.

The backwards iteration was done under the assumption that the only

Instead, iterate forwards, like before 85403d0a, and check the index
against the current list size in every iteration. This ensures that we
do not run out of bounds while the list is modified.
Also, retry the activation loop if the list was modified by a slot

When implementing a custom model there's the habit, in each and every
function that takes a QModelIndex, to carefully checking the index
passed by the caller. This index is checked for "legality" (*): does the
index belong to this model, is the index pointing to an existing row and
column, and so on. These checks are hand-rolled and, as such, slightly
different and possibly incomplete (i.e. wrong) every time.
What's worse, these checks are implemented via "ordinary" code (if
statements). However, passing an illegal index to a QAIM function is a
precondition violation, and as such does not (and must not) be
checked in ordinary conditions, as it triggers undefined behavior. On
the other hand, while debugging a custom model or a custom hierarchy
of (proxy) models, having such checks in place can be a significant
aid.
Enter checkIndex(): a debugging helper for QAbstractItemModel and its
subclasses. checkIndex() centralizes the checks for legality of a
given index. User code is free to assert on it, or have some other
fallback mechanism in case a check fails.
(*) Using "legality" here instead of "validity" in order to avoid
confusion between QModelIndex::isValid() and what checkIndex() really
does.

Since its initial implementation, QRingBuffer had the following
fragilities in the architecture:
- it does not guarantee validity of the pointers, if new data will
be appended. As an example, passing an address of the QRingBuffer
chunk as a parameter to the WriteFileEx() function on Windows
requires the stability of the pointer. So, we can't add new data
to the QRingBuffer until the overlapped operation completed
(related issues were fixed for QWindowsPipeWriter and QSerialPort
in 5.6 branch by introducing an intermediate byte array);
- inefficient reallocations in reserve(), if a shared chunk was
inserted in the queue (we can get a reallocation in the place
where we don't expect it:
char *writePtr = buffers.last().data() + tail; <- line #133
).
Proposed solution is to avoid reallocation by allocating a new
block instead. That was accomplished by introducing a QRingChunk
class which operates on a fixed byte array and implements head/tail
pointers strategy for each individual buffer in the queue. So,
QRingBuffer is no longer dependent on QByteArray's internal
shrink/growth algorithms.

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

This test makes sure that we do not introduce a regression where the
threads exited the inner loop over the queue before the queue was
empty. This was triggered by calling tryTake at least maxThreadCount
times, which left the same number of null pointers in the queue
and caused the inner loop to exit too soon for all the threads.

When parsing a date-time's zone, a stray Z denotes UTC (a.k.a. Zulu
time), despite not being a valid name for the zone. Clients parsing
such date strings had to treat the Z as a literal, rather than a
zone-ID, but then they got back a LocalTime instead of the UTC the
string actually described. So teach QTimeZoneParser to handle this
special case and adapt an existing test (that used a time ending in Z,
but had to treat it as a local time) to check this works.
[ChangeLog][QtCore][QDateTime] When parsing a time-zone, "Z" is now
recognized as an alias for UTC.

Since we don't document how many bytes one needs (it's 2496), it's
difficult for the caller to provide just enough data in the seed
sequence. Moreover, since std::mt19937 doesn't make it easy to provide
the ideal size either, we can't actually write code that operates
optimally given a quint32 range either -- we only provide it via
std::seed_seq, which is inefficient.
However, we can do it internally by passing QRandomGenerator to the
std::mersenne_twister_engine constructor, as it's designed to work.

The previous version was good, just not optimal. Because the input was
an unsigned 64-bit number, compilers needed to generate extra code to
deal with HW instructions that only convert 64-bit signed input. And
that was useless because a double uniformly distributed from 0 to 1 can
only have 53 bits of randomness.
The previous implementation did exactly what the Microsoft libstdc++ and
libc++ implementations do. In my opinion, those implementations have an
imperfect distribution, which is corrected in this commit. In those, all
random input bigger than 0x20000000000000 has a different frequency
compared to input below that mark. For example, both 0x20000000000000
and 0x20000000000001 produce the same result (4.8828125e-4).
What's more, for the libc++ and MSVC implementations, input between
0xfffffffffffff001 and 0xffffffffffffffff results in 1.0 (probability 1
in 2⁵³), even though the Standard is very clear that the result should
be strictly less than 1. GCC 7's libstdc++ doesn't have this issue,
whereas the versions before would enter an infinite loop.

attempt (and hopefully the charm).
Instead of modifying the path that the user provides, go straight ahead
and declare it invalid. This is supported by RFC 3986, which declares
this expansion impossible:
relative-part = "//" authority path-abempty
/ path-absolute
/ path-noscheme
/ path-empty
path-abempty = *( "/" segment )
path-absolute = "/" [ segment-nz *( "/" segment ) ]
path-noscheme = segment-nz-nc *( "/" segment )
The "path-abempty" and "path-noscheme" cases are the two issues we
already handle. This commit adds the third one: path-absolute, which
requires that the first segment of the path be of non-zero length.
That is, it is now possible again to have http://example.com//path
constructed piece-wise, without it producing http://example.com/path.
Additionally, it catches the case of http://example.com//path parsed
