With this change, the tablet keyboard layout both 7inch and 10inch use
quite similar one of the ordinal PC.  The differences from the ordinal
PC keyboard layout are:

- Move letter THAL from the most left of digits' row to the most left
  of 3rd row.
- Move letter DAL from the most right of 1st row to the most right of
  3rd row.
- Omit ligature LAM with ALEF from 3rd row and move to more keys of
  letter LAM on 2nd row.

The phone keyboard layout is the same one of the tablet except:

- Omit letter YEH with HAMZA avobe from 3rd row and move to more keys
  of letter ALEF MAKSURA on 3rd row.

The first key and the last of the row are automatically marked as left
and right edge key respectively.  The existence of Spacer will prevent
those automatic marking.

This change introduces the following features to Keyboard XML format.

 * "keyXPos" can specify the key X coordinate directly.
 * "keyXPos" can be negative. The X coordinate will be calcluated from
    the right edge of the keyboard toward left.
 * "keyWidth" can be zero to be filled up to the right side.
 * "keyWidth can be negative. The key will be filled up to both sides.
 * Spacer's horizontalGap is renamed as keyWidth, and can be inherited
   from key-style.
 * Spacer can have keyXPos attribute.

Using these syntax, all keyboard layouts have been re-written.

Ic4df2a9a introduced new keyboard layouts for Hebrew and Arabic.
This change adds a comment to them alongside with trailing
whitespace suppression.

This change explicitly limits its scope to files introduced by
Ic4df2a9a. It replaces I48927626 which has been deemed too reckless.

The Arabic keyboard is more or less based on PC keyboard and other
sources. It has no means to input diacritics at the moment.
Some data for the Hebrew keyboard was already there, but not used.
This change splits phone and tablet layout and consolidates the
tablet one to something that seems sensible. It can't input diacritics
either at the moment.

Other shortcomings affect those keyboards. For example, normal
Hebrew keyboards switch to capital QWERTY keyboard with shift on,
as there are no capital Hebrew characters, but this version does not
feature this.

It should be mostly possible already to enter Arabic or Hebrew with
these keyboards however.
