Seth Hillbrand 62f24aca1e Fix Connectivity Asserts in new COMMIT structure
The connection graph should only be updated within the commit structure
because this is the only time the connectivity should be changed.  We
want any connectivity changes to be included in the commit as well, so
this should be stored prior to the undo/redo list mods

Wayne Stambaugh 831a6d55fc Fix potential stale pointer bug in schematic highlight connection code.
SCH_CONNECTION objects are temporary and can become stale any time the
connectivity is updated.  Keeping them around to reference later is a
bad idea.  Even if the object pointer is still valid in an SCH_ITEM in
the undo/redo buffers, comparing the pointer against another pointer as
a test to see if they are the same connection is not valid.  Saving the
connection name is safe and ensures the connection is the same even if
the pointers differ.

Mike Williams e51ab86225 Schematic Drag: fixes and improvements
Fixes:
* Various special cases around junctions on pins and dragging.

* Some rotations of endpoints resulting in a 45 degree rotate.

* Some cases where it was possible to get a line with neither
  endpoint selected, and also substractive unselecting only one of two
  selected endpoints unselecting both.

* Use line midpoint for sorting.  Start and endpoints aren't
  consistent in the order they appear on the X or Y axis. So,
  we need to use the midpoint for our position for consistent
  sorting when dragging groups of parallel lines where some
  have the start and end reversed.

Other:
* Rename TEMP_SELECTED TO SELECTED_BY_DRAG. This is the actual meaning
  of the flag, and should reduce confusion as
  to when it should be used.

* Move usage of TEMP_SELECTED as an algorithmic mark to CANDIDATE
  instead.

* Fix mistaken clearing of START_POINT and ENDPOINT.

* Move endpoint setting and clearing out of narrowSelection, and into
  selectPoint and selectMultiple.

* Don't show dangling end warnings on new lines

Seth Hillbrand 854472d550 Prevent automatic RTree recaching
Calling UpdateItem() may be performed by in a common loop, e.g. for(
SCH_ITEM* item : GetScreen()->Items() ) or similar.  We cannot call
GetScreen()->Update( SCH_ITEM* ) in this routine as it will remove and
re-add the item to the RTree, invalidating iterators.  If needed, the
items need to be cached to an external container before updating

Also expunges the horrifically named std::remove and std::remove_if
(neither of which remove anything).

Seth Hillbrand 71602475eb Allow rotate/mirror even when dragging
Keeps the lines connected but doesn't solve the crossed-wire mixups.
This allows common usage (mirroring labels/rotating segments) and leaves
prevention of the crossed wires to the user.

We can't really prevent crossed wires when rotating e.g. a part with
wires connected to 4 sides and users will not expect that.  But we
should not disable useful features like mirroring multiple parallel
items to avoid a known impossible situation

Also provides an alternative solution to 345f506f0c that allows us to
rotate groups without destroying connections on hover

Seth Hillbrand 3b04b602d9 Don't walk text/labels when mirroring
We have a fixed bottom-align for the text and labels in eeschema.
Therefore, mirroring vertically needs to account for the text's offset
from the bounding box center.
