Subject: [PATCH 2/3] Fix high CPU utilization caused by key repeat timer
Key repeat timer has been broken since the beginning.
The key repeat timer leaked timer instances while processing the event,
causing the accumulation of unprocessed timer events and high CPU
utilization.
Fix the issue by killing the original timer (long press delay 600 ms)
and starting the key repeat timer (repeat delay 50 ms) once.
[ChangeLog] Fixed high CPU utilization caused by key repeat timer.

Subject: [PATCH 3/3] Fix processing of hard Qt::Key_Backspace and
Qt::Key_Delete
Even though the virtual keyboard does not support hard keys at the
moment, this kind of processing could be possible in the future.
In the mean time, fix processing of backspace and delete keys.
In particular, if such key is pressed the pre-edit text is not empty:
- Reset input method state (should not modify pre-edit)
- Clear pre-edit
- Return true (to indicate no further processing is required)
[ChangeLog] Fix processing of hard backspace and delete keys.
