Karsten Heimrich b75c82f645 Resolve Qt6 TODO items, replace Median and BlockSizeManager
* Replaces the, only internaly used, implementation of template
  class Median with a fixed size none templated version.
* Replaces BlockSizeManager with an updated BlockSizeManager V2,
  but keeping the original name.
* adapt the auto-test to take the fixed size array into account

Martin Smith 4f9575ecbc doc: Fix all qdoc errors in QtConcurrent
These errors resulted from the improved parsing provided
by clang, which required rethinking which elements of the
QtConcurrent API should be visible to clangqdoc. The basic
problem is that clang must see declarations for all types
used by a type, or else it either gets lost and fails to
parse a type correctly, or it simply refuses to include
the type in its AST.

Thiago Macieira b630a4513c QtConcurrent: use QDeadlineTimer to get the clock tick
Instead of duplicating what QElapsedTimer & QDeadlineTimer already do.
Well, technically speaking, we aren't getting ticks, but nanoseconds
now, but the times are only used in comparisons with each other, to
measure the control overhead, so the unit in which they are measured
doesn't matter.

This also makes all OSes use the same type of timers. There's no
exception for per-thread timing.

Ralf Nolden 37ef6b4968 OpenBSD: use clock_gettime() provided by OS
The use of clock_gettime() is limited to systems having _POSIX_TIMERS
defined, however OpenBSD implements clock_gettime() but does not have the
posix define. Enable using clock_gettime() on OpenBSD as well.

Create a MedianDouble class and V2 version of BlockSizeManager, which
use a fixed size array of double (since we always use 7 elements
to calculate the median anyway).

Jani Heikkinen 1a88b2f768 Updated license headers
From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/

Updated license headers to use new LGPL header instead of LGPL21 one
(in those files which will be under LGPL v3)

Jani Heikkinen 83a5694dc2 Update copyright headers
Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Outdated header.LGPL removed (use header.LGPL21 instead)

Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)

Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

Marc Mutz 935e52108d QtConcurrent::IterateKernel: fix a race on a cache variable
getticks() can be called concurrently, so accessing a non-atomic static long,
even when the assignment will produce the same value in evey case, constitutes
a data race.

Fixed by making 'useThreadCpuTime' atomic.

Since atomic long's might not be supported on all platforms, use an
atomic int instead. To avoid a narrowing conversion, and since we're
not interested in the return value of sysconf(), only whether it
succeeded, convert any non-error return value to 0 prior to storing
in the atomic.
