The old unix locking code is no longer working on unix since it locks on
a file descriptor, but QSaveFile creates a new file, and as a result we
get the lock on the wrong file. Also there is no need to keep the lock
held only for reading as QSaveFile is atomic. It just needs to be held
when doing a read before writing.
As a result, since we don't hold the same lock, there could be a race
with an application running an older version of Qt if they are writing
on the same configuration file.
[ChangeLog][QtCore][QSettings] Fixed data loss while writing the config
to the disk fails.
[ChangeLog][Important behavior changes] The locking mechanism inside
QSettings has changed and is no longer compatible with the one of
previous versions of Qt. There might be corruption if two applications
running different versions of Qt are writing to the same config file
at the same time. You must also now have write permissions in the
directory containing the settings file in order to write settings

The default in QTextStream is to use the C locale, so default

was to use group separators (which is the QLocale default too). This
commit makes QTextStream respect a QLocale in which the
OmitGroupSeparators option had been set.

Allow to alter the default configuration for categories by passing a
message type: All message types with lower severity are disabled in this
category.
This is useful for libraries, which shouldn't mess with the category
registry itself: Setting rules, a category filter ... might cause
conflicts and ordering problems, so this API should be reserved to the
specific application.
For the Qt categories, we have code in the default category filter that
disables the 'debug' category. However, this is hardcoded, and there's no
way so far for other libraries to get the same behavior. With this patch
one can get the same behavior:
Q_LOGGING_CATEGORY(DRIVER_USB_EVENTS, "driver.usb.events", QtWarningMsg);
[ChangeLog][QtCore][Logging] Added QtMsgType argument to QLoggingCategory
constructor and Q_LOGGING_CATEGORY macro that controls the default
category configuration.

~QDebug() removes any trailing space if autoInsertSpaces() is true.
However, if one uses QDebugStateSaver the global autoInsertSpaces might
be false, but a space was added by a custom operator<<.
Explicitly check for this in QDebugStateSaverPrivate::restoreState. Remove
any trailing space if the local state asks for adding trailing spaces, but
the original one doesn't. Add a trailing space if the local state doesn't
ask for one, but the global state does.

On Unix systems where the GUI event dispatcher uses a notification
system for socket notifiers that is out of band compared to select(),
it's possible for the QSocketNotifier to activate after the pipe has
been read from. When that happened, the ioctl(2) call with FIONREAD
might return 0 bytes available, which we interpreted to mean EOF.
Instead of doing that, always try to read at least one byte and examine
the returned byte count from read(2). If it returns 0, that's a real
EOF; if it returns -1 EWOULDBLOCK, we simply ignore the situation.
That's the case on OS X: the Cocoa event dispatcher uses CFSocket to get
notifications and those use kevent (and, apparently, an auxiliary
thread) instead of an in-thread select() or poll(). That means the event
loop would activate the QSocketNotifier even though there is nothing to
be read.
