Most posix_spawn implementations are done using fork(), so the only way
to report errors afer fork() is via a special exit code.

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.

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.

The most common use case for QTextStream::readLine() is reading
a file line by line in a loop. The existing readLine() method
allocates new memory for each line, that results in a loss of
speed. The introduced overload can use already allocated memory.
Besides it allows you to not think about filesystem specifics.
The current QFile documentation suggests a separate way to read
files from /proc filesystem. With this overload it's possible
to use the same idiom in all cases:
QTextStream in(&file);
QString line;
while (in.readLine(&line)) {
process_line(line);
}
The idea was inspired by the blog post of Ivan Čukić:
