bc6ffcd0c5 Torrent example: Replace the last Java-style iterator with STL ones
Scope a previous iterator variable better so we can re-use 'it' as the
iterator name.

eae4668afa Torrent example: replace a QMultiMap with a sorted vector
This came about trying to remove the Java-style iterator. It was used to
iterate in reverse order, something QMap can't do, easily, due to lack
of rbegin()/rend(). Instead of writing ugly loops, use a vector of pairs,
fill it, sort it, then iterate over that one in reverse.

f0463f0cc6 Torrent example: add missing qAsConst()
The function is const, but the d-pointer doesn't propagate it (raw pointer),
so we need the qAsConst() even here.

54590c4f8a Torrent example: rewrite some very convoluted code
The old code iterated over the peer list, inserting active peers into
a QSet, curiously not stopping to search for clients if it had already
determined the peer to be active.

It then iterated over the peers again, storing the indexes of the
peers it had determined to be active in the first loop, in a QList.

It _then_ iterated over the index list, in reverse, calling removeAt()
on the peers list.

<sean parent>That's a remove_if!</sean parent>

The twist is, that only some maximum number of inactive peers should
be removed, just enough to bring the number of peers below a
predefined number.

To solve, use a lambda that keeps track of the number of times it has
returned true, returning false once the count drops to zero. We can't
use a mutable lambda here, since the STL algorithms are allowed to
copy the predicate as many times as they wish, and, indeed, remove_if
is commonly implemented by calling find_if. But the standard
guarantees exactly one application of the predicate per element, so we
can assume that we're not called again on the same element, and
therefore keep a reference to an external count.

With this, what was a horrible mess becomes a single call to remove_if.

Also change a while(--n) c.removeFirst() loop to a single call of
range-erase.

19b0ce5daa Change almost all other uses of qrand() to QRandomGenerator
The vast majority is actually switched to QRandomGenerator::bounded(),
which gives a mostly uniform distribution over the [0, bound)
range. There are very few floating point cases left, as many of those
that did use floating point did not need to, after all. (I did leave
some that were too ugly for me to understand)

This commit also found a couple of calls to rand() instead of qrand().

This commit does not include changes to SSL code that continues to use
qrand() (job for someone else):
  src/network/ssl/qsslkey_qt.cpp
  src/network/ssl/qsslsocket_mac.cpp
  tests/auto/network/ssl/qsslsocket/tst_qsslsocket.cpp

9e49778380 Fix/adapt the uses of {to,set,from}Time_t in the qtbase source code
Move those to the equivalent {to,set,from}SecsSinceEpoch(), except for
the cases that did QDateTime::currentDateTime{,Utc}().toTime_t. Those
are best implemented with QDateTime::currentSecsSinceEpoch().

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

b11317a643 Whitespace cleanup: remove trailing whitespace
Remove all trailing whitespace from the following list of files:
*.cpp *.h *.conf *.qdoc *.pro *.pri *.mm *.rc *.pl *.qps *.xpm *.txt *README
excluding 3rdparty, test-data and auto generated code.

Note A): the only non 3rdparty c++-files that still
have trailing whitespace after this change are:
* src/corelib/codecs/cp949codetbl_p.h
* src/corelib/codecs/qjpunicode.cpp
* src/corelib/codecs/qbig5codec.cpp
* src/corelib/xml/qxmlstream_p.h
* src/tools/qdoc/qmlparser/qqmljsgrammar.cpp
* src/tools/uic/ui4.cpp
* tests/auto/other/qtokenautomaton/tokenizers/*
* tests/benchmarks/corelib/tools/qstring/data.cpp
* util/lexgen/tokenizer.cpp

Note B): in about 30 files some overlapping 'leading tab' and
'TAB character in non-leading whitespace' issues have been fixed
to make the sanity bot happy. Plus some general ws-fixes here
and there as asked for during review.
