We were running into various corner conditions where a tool's event
loop would exit while the tool was still active, or the tool would
get popped while we were still in the event loop. (A lot of these
had to do with the POINT_EDITOR's, but not all of them.)
The new architecture:
1) tools always do a Push()/Pop()
2) everyone is responsible for their own pops; no more stack-clearing
on a cancel
3) CancelInteractive events go to all tools to facilitate (2)
It's a bit of a hack because they're statically initialized and
so we can't make use of the _() macro. We do still want it in the
code, however, because the string harvesting is based off of it.

If a tool called something like clearSelection while processing a
MOUSE_CLICK, the SELECTION_TOOL will pass the clearSelection
COMMAND_EVENT because it handles it as a transition, not as an
event. Because m_passEvent is effectively global, the tool manager
would then interpret that as passing the MOUSE_CLICK and we'd end
up processing the click by multiple tools.
It was confusing that the primary frames registered their tools
differently than the other frames. In addition, since the other
frames also added their own tools, foo_actions::RegisterAllTools()
didn't really register all tool but rather those used by the
principal frame (PCB_EDIT_FRAME, SCH_EDIT_FRAME, etc.)
Put the cursor and pan control TOOL_ACTIONs in ACTION,
and refer to them in that way.
The handlers are currently identical in Pcbnew and Cvpcb,
and Gerbview (and all canvases) can benefit from them as well
if they are in libcommon. Also saves duplicated code.

... and GetMsgPanelInfo.
Step 4 in the g_UserUnit eradication effort.
Also removes a couple of conversion routines that were close
enough to extinction.

This not only reduces the number of different mechanisms, but
will also reduce (yet again) the number of Clarify Selection
pop-ups (because the CLIENT_SELECTION_FILTER runs before the
pop-up, while SanitizePads ran after it).

(cherry picked from commit e50a993)
The SELECTION is a std::set. Numerical dereference of item n is O(n) as
the iterator is not random access. Therefore, a for loop using
numerical dereference is O(n!) and quickly slows.
We avoid this by storing items to remove separately while iterating and
then removing the items after we complete.
