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).

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.

Fix shortcut handling with non-latin layouts

Shortcut handling with non-latin keyboard layouts
were broken for checks like:

QKeyEvent key = ...;
key == QKeySequence::SelectAll

In Qt4 this was handled transparently when getting
keysym from XLookupString. When ctrl modifier was set,
XLookupString performed "keysym transformation" to obtain
a latin keysym. Still this did not solve the non-latin
shortcut issues for all cases due to some of Xlib
assumptions which could not be controled by user.

This patch implements XLookupString-like behavior
in lookupLatinKeysym(). It is not a 1-to-1 copy of how
XLookupString perfoms latin keysym lookup, but it
serves our needs just fine. lookupLatinKeysym() also
handles the cases that did not work in Qt4 with
XLookupString, thanks to libxkbcommon keymap query API.

And lookupLatinKeysym() replaces the fragile implementation
of "fallback latin key" code path in possibleKeys().
