Allow hostname from lock files to be empty

The common format for lock files is to only contain the PID.
(See http://www.pathname.com/fhs/2.2/fhs-5.9.html)
Qt includes some extra information but we can not expect this
information to be present. Otherwise lock files created by other
(non-Qt) processes are not handled correctly.

Remove trailing '\n' in qFormatLogMessage output

Do not automatically add a \n to all messages formatted by
qFormatLogMessage. Some backends require a final newline,
some don't, so it's best to only append it where it's actually needed.

The returned string will be null if the pattern is empty. This allows
to differentiate between the case that the pattern just didn't apply
(empty line is printed), and the case that qSetMessagePattern(QString())
have been called (nothing is printed).

QStorageInfo: include qt_windows.h instead of Windows.h

This fixes a compilation issue with X-MinGW builds and
is more appropriate here.

fix crash when dropping a file into an empty QTextEdit

Since commit be0bfe09ee4b99e9ab45c6898949b5d144e77a29 we return -1 in
QTextEngine::findItem if the item cannot be found.
Calling code must be prepared for this case.
Otherwise we run into an out-of-bounds vector access later on.

QSettings: Fix handling of long long ints with CFPreferences back-end.

The CFNumberGetValue() function does not work as advertised: For some
(but not all) CFNumbers containing a long long value outside the range
of int, it returns true when asked to convert to an int, so the wrong
value is extracted from the CFNumber.
As a workaround, use CFNumberGetType() to find out whether the value
is actually an int.
