Installing plugins into a data path is a very bad idea, even more so
when the path disagrees with the non-prefix location.

The default LIPI_ROOT contains both the plugins and the projects needed
at runtime for handwriting recognition. This change adds new environment
variable LIPI_LIB which points to location for plugins only. This allows
the separation of the two.

This change wraps the entire C++ API into namespace.

In practice, all the C++ interfaces inside the qtvirtualkeyboard plugin
are private, except the QPlatformInputContext plugin API. Even the
AbstractInputMethod and AbstractInputPanel are not really a public in
the sense that they could be used outside the plugin. At least it does
not make sense, since there is no way to extend the virtual keyboard
functionality without recompiling the plugin.

This change improves the user experience by reducing the time
spent waiting the HWR task to complete.

Previously the recognition was started after the recognition
timer expired. This caused the total overhead of the recognition
to be summed on top of the recognition timer, reducing the user
experience in low performance devices. Now the idle time (during
the recognition timer) is used for the benefit of HWR task, so that
in optimal case, the recognition result is available immediately
after the recognition timer expires. If the HWR task takes longer
to process than the recognition timer, the results will be provided
as soon as the HWR task is done.

Ongoing recognition task is cancelled if the user continues drawing
while the recognition timer is running. If the recognition task is
already completed, the current result is ignored and the result
from the next recognition task is used instead.

This change adds a reference implementation of the handwriting
input method.

The handwriting support is enabled by adding CONFIG+=lipi-toolkit
to the qmake command line.

The current implementation uses alphanumeric model for handwriting
recognition, which come bundled in the lipi toolkit.
