In the case when user's local encoding is UTF-8, QDirIterator
may list entries which names can't be correctly converted from
UTF-8 to UTF-16, e.g. for "\xC0\xB0" file name QDirIterator::fileName()
returns "\uFFFD\uFFFD" (FFFD is a code of Replacement Character).
The problem is that you can't do anything with such directory
entries because there is no way to get the original entry names.
List only those names that can be converted to QString
and then back to the local encoding without corruption.

This allows us to make sure that the PID we read is from the same boot
as we are right now running. The collision could happen on embedded
systems where the boot sequence is fixed, so all the same processes
would have the exact same PIDs after reboot as they did before.
[ChangeLog][QtCore][QLockFile] QLockFile can now properly conclude that
a lock file from a previous boot of the same device is stale and can be
removed. This is implemented only for Linux and Apple operating systems.

Since we very often need to write our intrinsic-using code in C to avoid
"leakage" of not-inlined inline functions, this file is very handy.

The RENAME_NOREPLACE flag is supported for all Linux local filesystems,
since that can be easily checked by the VFS layer (it knows which files
exist and which ones don't). For non-local filesystems, the backend
needs support and that might need server-side support too. So we may get
EINVAL errors for those, in which case we fall back to link/unlink,
which in turn can fall back to rename().
EINVAL can also happen if we attempt to make a directory a
subdirectory of itself. In that case, we will attempt to link() it,
which will result in EPERM as we can't hardlink directories. Then we try
rename() again, which should result in the expected EINVAL.

This warning used to be part of -Wconversion, but that generates too
more noise than we're willing to fix now (like conversion from qint64 to
int). The float conversion does trigger for conversion from double to
float, as shown in all the QVectorND uses of float, but more
importantly, it triggers on passing floats to ints.

Discussed during Qt Contributor Summit 2017. We concluded that we don't
want to make these functions public, as they do not follow Qt coding
style API. Specifically,
qStartsWith(a, b)
is not easily understood which argument is the needle and which argument
is the haystack (same problem memcpy() has). Compare that to
a.startsWith(b)
which can clearly be read in English as a subject-verb-object sentence.
This commit removes the unit tests that called compare().

I've marked three places to use the system CSPRNG:
1) the QHash seed
2) QUuid
3) QAuthenticator

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.

Commits aba336c2b4ad8926dc8a000718bbb7f8a6d5a72d (in Qt 5.2) and
aba336c2b4ad8926dc8a000718bbb7f8a6d5a72d (in 5.6) both tried to deal
with this problem, with different levels of success. This is the third
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
from full URL then followed by setAuthority("").

By judiciously positioning of the bits, we can optimize for the case of
threads trying to acquire a single token, which is what QSemaphore
should be mostly used for, as it matches the POSIX Semaphore API
(sem_wait, sem_timedwait and sem_trywait). If there are only waiters
waiting for a single token, we know that adding n tokens means n threads
can wake up.
This optimizes for multi-token waiters too. For example, if we have 50
single-token waiters and 50 multi-token waiters, a sem.release(5) will
wake up 55 threads instead of 100.

NSTimeInterval is a typedef for double, but the code stored its value in
an int, and only then multiplied by 1000.
Fix by only truncating NSTimeIntervals to int(64_t) *after* the
multiplication by 1e3 to get milliseconds.
While it's highly unlikely that a transition will have fractional seconds
length, don't assume if you can just calculate the more exact result.

There are a couple of Q_ASSERT wrapped by the new noexcepts, but most of
those aren't validation of external parameters, only of internal
construction. The two exceptions are the checks for pointer alignment.

The documentation of QKeyValueIterator was in the wrong place. This
patch moves it with the other iterators documentation.

That overload documentation was missing the "exact" qualifier regarding
the search result.

<future> is needed by QThread::create. Instead of a fragile series
of preprocessor tests, move its detection to a configure test.
This dramatically simplifies the code, but on the other hand ties
the availability of QThread::create() to the system used to compile
Qt (rather the one used to compile an application).

That was stupid for two reasons. First, applicationName() can be changed
by the user by calling QCoreApplication::setApplicationName(), so if
that happens, we won't be able to properly identify a lock belonging to a
given application because the name changed.
Second, because applicationName() is not what we compare to. Instead,
let's use processNameByPid() on both content creation and verification.
[ChangeLog][QtCore][QLockFile] Fixed a bug that would cause QLockFile
mis-identify valid lock files as stale if the application name was set
with QCoreApplication::setApplicationName().

We duplicated both the creation of the contents and the check if the
file was stale. Centralize everything in qlockfile.cpp.

F_SETLK is bad. Explanation in the comment. And flock(2) does work with
NFS on Linux, so let's just stick to that, which is simpler.
We only use the file locks when we attempt to delete an apparently stale
lock: that is, for a lock file that is at least staleLockTime old.

This is enabled by default with Xcode 9 and would therefore be seen by
anyone calling this function from C or Objective-C.

Apparently it's all meant to be in alphabetic order by feature name
(except for where it isn't). So move my new addition to it to where
that would put it, re-order everything else to follow that rule and
add a comment documenting it.
