The attached patch introduces separation between id-base properties in
prototype instances and the rest of objects so it is possible to
allocate some ids for each instance and the rest only for prototype. The
patch adds to each descendants of IdScriptable a special prototypeFlag
which set to true only if object serves as a global prototype and all
methods that check/return ids first check for that flag. (This is the
reason for the patch size: diff is not very well in dealing with
indentation changes.)
In this way ids for prototype properties are completely hidden from
potential subclasses and there is no need to define methods like
getMaximumId in most cases, only if some ids present in each instance,
IdScriptable.maxInstanceId should be overridden to return max id present
in each instance.
The patch also replaces 2 boolean fields in IdScriptable by bit masks in
the setupFlag field.
