Shift positions for lineBreakType

to keep them consistent with positions for all other flags.
This changes the internal behavior so that attributes[0].lineBreakType now means
"break opportunity at start of the text (before the first character in the string)"
and is always assigned with HB_NoBreak to conform rule LB2
(see http://www.unicode.org/reports/tr14/#LB2).

The current implementation is based on the sample implementation from tr14
that aimed to be as simple as possible rather than to be optimal.
From now, we can use pieces of the attributes array "as is"
without having to adjust some positions. Or we can analize some long text
by chunks (e.g. paragraph by paragraph) and consume less memory.

This introduces a minor overhead that will be eliminated shortly.

Set the whiteSpace flag outside the grapheme and the line breaking loop

The white spaces determination doesn't belong to the text breaking algorithm.
A proper breaking implementation shouldn't assume spaces are
break opportunities (actually, space is allowed to be a grapheme base);
However, the whiteSpace flag should never be checked alone while iterating
over the text to find the space sequence; the grapheme boundaries should always
be taken into account. This covers the SMP code points in UTF-16 text and
graphemes that consist of a space followed with one or more grapheme extenders.

statemachine: Make delayed event posting work from secondary thread

postDelayedEvent() and cancelDelayedEvent() are marked as thread-safe
in the documentation. Unfortunately, they didn't actually work when
called from another thread; they just produced some warnings:

QObject::startTimer: timers cannot be started from another thread
QObject::killTimer: timers cannot be stopped from another thread

As the warnings indicate, the issue was that postDelayedEvent()
(cancelDelayedEvent()) unconditionally called QObject::startTimer()
(stopTimer()), i.e. without considering which thread the function
was called from.

If the function is called from a different thread, the actual
starting/stopping of the associated timer is now done from the
correct thread, by asynchronously calling a private slot on the
state machine.

This also means that the raw timer id can no longer be used as the
id of the delayed event, since a valid event id must be returned
before the timer has started. The state machine now manages those
ids itself (using a QFreeList, just like startTimer() and
killTimer() do), and also keeps a mapping from timer id to event
id once the timer has been started. This is inherently more complex
than before, but at least the API should work as advertised/intended
now.

Remove support for Qt 4 style plugins
