Clean up Position.h

I would like to make Position objects aware of the meaning of their container
and m_offset values.  This will require removing direct construction of
Positions objects.

Eventually positions will have the ability to specify [node, after], [node,
before] in addition to [node, childOffset].  Positions already have this
ability, but only for content which editing "ignores"
(editingIgnoresContent(node) returns true).  When editingIgnoresContent returns
true, then Positions [node, 0] and [node, 1] are interpreted as [node, before]
and [node, after] by some parts of the editing code, but not all.  you don't
actually know what type of position you're dealing with up-front, only in
certain places will [node, 0 (before)] be converted into [node->parentNode(),
node->nodeIndex()].

I would like to fix positions to hide the details of m_offset and container
(which is not always really the "container" for the position, and add new
accessors to get that kind of information in a consistent way for all
positions.

Anyway, the first steps for this are to clean up Position objects to not make
m_offset and container public.  I'll attach patches to do this.
