Differentiates better between the EDA_ITEM IsModified(), referring to
items themselves changing and the EDA_SCREEN IsContentModified(),
referring to whether we have made any unsaved changes.
Save sheet and symbol instance information to the clipboard on copy
Load sheet and symbol instance information from the clipboard on paste
and renumber page numbers after loading.
Correctly handle pasting in a multiple hierarchy by ensuring symbol and
sheet instances are updated for all instances of the destination sheet.

Avoid code duplication by moving all common code to a new function
SCH_SEXPR_PLUGIN::saveInstances
Also fixes a bug that was resulting in footprint and value information
not being saved for subsheets that were root sheets in a different
project.
- new function SCH_SHEET_LIST::SortByPageNumbers() which uses SCH_SHEET::ComparePageNum for the sorting algorithm
- SortByPageNumbers() is called after every call to BuildSheetList()
1) Generalize SCH_ITEM owners (SCH_COMPONENT, SCH_SHEET, and now
SCH_GLOBALLABEL)
2) Generalize hypertext items
3) Use SCH_FIELD autoplace infrastructure for placing intersheet
references
4) Use textVar infrastructure for buildin intersheet references.
As an important side-effect this also fixes the undo issues with
intersheet refs.
The groundwork has now been laid for per sheet instance data. Initially
this only supports sheet page numbers but could be expanded to include
other per sheet instance information.
ADDED: Support for user defined schematic page numbers.
1) use SCH_COMPONENT::GetRef(), GetValue() and GetFootprint() when
instance-specific info is needed
2) update UpdateAllScreenReferences() to handle value and footprint.
3) BACKANNO is CvPcb's handler, not back annotation's handler. Which
means it needs GUI behaviour, not back annotation behaviour.

Also fixes a couple of bugs where resolving a textVar reference
to the refDes or unit wouldn't get the correct value in a
hierarchical schematic. (Unlogged.)

Don't copy the recursion test cache when copy-constructing
SCH_SHEET_PATHs as it's not needed in connectivity
Fix a few places that were copying unnecessarily
Set up a new lineage for SCH_ITEMS to get back to the SCHEMATIC
they live on: Items will all be parented to the SCH_SCREEN that
they are added to, and each SCH_SCREEN will point back to the
SCHEMATIC that it is part of. Note that this hierarchy is not
the same as the actual schematic hierarchy, which continues to
be managed through SCH_SHEETs and SCH_SHEET_PATHS.
There has been a long standing (since the beginning of the project?)
issue with sharing schematics between projects. It has been somewhat
supported for complex hierarchies (a sheet shared multiple times in a
single design) but it has not been well supported for simple hierarchies
(the symbol references cannot be changed in the shared schematic). This
issue has been resolved by moving all of the symbol instance sheet paths
from the symbol definitions in the all of the project files and save all
symbol path instances in the root sheet. This ensures that orphaned
symbol instance paths do not accumulate in shared schematic files and
that designs that reuse schematic in simple hierarchies can how have
different references. It also allows the root schematic from one project
to be uses as a sub-sheet in another project.
When legacy schematics are loaded, all sheet and symbol UUIDs are
converted from time stamps to true UUIDs. This is done to ensure there
are no sheet path instance clashes between projects. That being said,
there are no checks for this. It is assumed that the probability of
UUID clashes is so low that it doesn't make sense to test for them.
Also fixes a bug where we were depending on the old deque stuff's
deterministic traversal, which isn't provided by the new RTree stuff.
