JQM: Fix buttonmarkup bug keeping ui-btn-down class
In multi-touch devices, browsers receive multiple touch events at same
time, but there are some abnormal cases that JQM does not handle.
* 'touchcancel'
When a button is long-pressed, some browsers fire 'touchcancel'
event and show some browser menu popup. In this case, the button
still has 'ui-btn-down-*' class, which make button seem to be
pressed.
NOTE: Tizen browser does not fire 'touchcancel'!
* 'touchend' but no 'vmouseup'
When a button and the other element are touched together almost
same time(from button to other element, with slight time gap),
the 'touchend' event is fired to the button, but 'vmouseup' does
not fired sometimes. But JQM does handle only 'vmouseup', so the
'ui-btn-down-*' class is still remained.
(It may be caused by JQM vmouse* event bug.)
This JQM patch adds two events, 'touchcancel' and 'touchend' to
replace 'ui-btn-down-*' class to 'ui-btn-up-*'. Tested on Tizen target
and emulator.
Fix N_SE-19155.
