Eeschema: Fix a (minor but annoying) bug detected by coverity which prevent Eeschema to draw components in "fast mode" (i;e. without pin texts) when they are moved, due to a draw parameter which was incorrectly used.

Move items rework: enhancements: for some items (sheets, components, bus entries) the mouse cursor is no more wrapped to the anchor. For large symbols, this is better: they are more easy to place.
There is also a change when starting a move item command: the full screen is redraw, and therefore there is no artifact due to the XOR draw mode.
Some other minor coverity fixes (uninitialized members).
