libxcwm: Support for WM_TRANSIENT_FOR and WM_SIZE_HINTS added

Getting values of ICCCM properties has been changed to use the
xcb_icccm.h functions available to simplify library code.

On receiving a mapping event, WM_TRANSIENT_FOR and WM_SIZE_HINTS for
window are checked for the window, and values in xcwm_window_t are
set.

Enumeration added for different EWMH window types, currently only
XCWM_WINDOW_TYPE_DIALOG and XCWM_WINDOW_TYPE_NORMAL are used. A
xcwm_sizing_t structure was added to hold WM_SIZE_HINT data for the
window.
