regtoosl/qeditor: port to the new description format

This big commit port qeditor from v1 to v2 register file format. Although
the display code was much simplified, the edit code had to be rewritten.
The new code also brings many improvement to the register display widget.

The new code also compiles with both Qt4 and Qt5, although it is recommended
to use Qt5 to get some improvements, especially in the layout of editor.
