507625d984 fix assertion in QProcess/Win
Do not call bytesAvailableInChannel if the source pipe end is
invalid. This is the case when redirecting channels on Windows.
The assertions in bytesAvailableInChannel were triggered whenever
an output process or output file was set and waitForBytesWritten
was called.

[ChangeLog][Important Behavior Changes] QDebug output for QStrings

8fdd1e3867 QLoggingCategory: fix default severity in Q_LOGGING_CATEGORY macro
[ChangeLog][QtCore][QLoggingCategory] Fixed behavior of default
severity passed to constructor or Q_LOGGING_CATEGORY with regards to
QtInfoMsg, which was previously treated as being more severe than
QtFatalMsg.

This is because the code was using the numeric value of QtMsgType as a
proxy for severity (via the <= operator), but the value of QtInfoMsg is
greater than QtFatalMsg. Instead, the severity ordering must be dealt
with explicitly.

edb5f22b0a consistently handle empty program string in QProcess::start overloads
All overloads of QProcess::start will now check whether the program
string is empty and in that case
  - set error to FailedToStart,
  - set errorString to "No program defined",
  - emit error.

Until now only one of the three overloads behaved like this.

As a side effect, start(QString(), QStringList()) will not crash on
Windows anymore.

qstrtoll and qstrtoull are now wrappers that try and keep the behavior
that we used to have.

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Outdated header.LGPL removed (use header.LGPL21 instead)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

8ca735762d Fix tst_process on QNX when using spawn
QNX posix_spawn() implementation actually allows for detecting whether a
non-existent process has failed to start.

75a2c81b00 Handle posix_spawn using exit code 127 to indicate fail-to-start
Most posix_spawn implementations are done using fork(), so the only way
to report errors afer fork() is via a special exit code.

1814142b7a Use forkfd in QProcess
Replace the existing code in QProcess that dealt with signaling of child
processes exiting with forkfd and spawnfd. The previous code was
convoluted and hard to maintain, having shown its age in the last
year. I've been running it for a year and a half and the new
implementation is definitely an improvement.

This change replaces support for the QNX Neutrino spawn() call with the
POSIX version. We lose the ability to do setsid(), but we gain quite a
few ioctls() that were done to fill in the file descriptor mapping
structure. That's also the only OS for which we have the ability to
thread-safely chdir() before the call to spawnfd().

Another advantage is that forkfd does not require a dedicated thread
running to handle child processes exiting.

c8849dd8d5 Use waitid with WNOWAIT in forkfd
The previous implementation required one syscall per child we're waiting
on to see which one exited. That means the algorithm was O(n).

This implementation uses WNOWAIT to find out which child exited and then
goes straight to that one. So it's O(1) on the number of children, but
runs 2 * number_of_children_that_exited + 1 syscalls, assuming there are
no race conditions with other threads. If there are or if a child not
started by forkfd exits, we'll still iterate over each child we're
managing to see which one exited.

It modifies the existing code so that it will do a waitid() with WNOWAIT
to check on the status of the child: if the child has exited, we'll try
to lock the entry so only one thread will do the final wait(). In the
case we read the PID, then the child exited, was reaped by another
thread, the PID got recycled and that child exited again, we'll fail to
lock the ProcessInfo entry so no harm comes. If by an absurd coincidence
this other child was started by forkfd() and its ProcessInfo is exactly
the one we are looking at, then we'll succeed in locking but that's a
benign race: we'll do what the other thread was trying to do and the
other thread will give up.

Future improvements to the algorithm are discussed in the Gerrit change.
