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.

A sheetpath is required to correctly resolve text variables.
Depending on currentSheet is rife with bugs.
There are many places where we do *not* want to be prepending
field names to the field values, such as netlisting,
building PDF hypertext menus, etc.
Also, Find/Replace needs to work on unresolved text, as
that's what we're going to display (and if replace nuked
your variable references you wouldn't be happy).

- Ensure that critical paths (ERC/netlister) are fully-rechecked
- Handle symbol/pin distinction in change markers
- Fully connect hierarchical pins in one pass descending

Previously, almost all connectivity updates were full updates, meaning
that the entire connectivity graph would be rebuilt each time a change
was made to the schematic. This update modifies the update to only
correct the subgraphs that are directly affected by the change.
It uses the existing connection graph to find all affected subgraphs as
well as connections to the changes based on the visible schematic.
These elements are removed from the existing connectivity graph and
marked dirty. They then have a new connectivity graph built only around
their changes. The resulting graph is merged into the original.
Currently, this ability is behind an advanced config flag
`IncrementalConnectivity` while testing.

SCH_EDIT_FRAME::RecalculateConnections() calls SchematicCleanup and then
resets the connectivity graph and recalculates it. OnModify() also
calls RecalculateConnections(). For long calculation schematics, this
can impact usability
The pressure relief valve was not useful for common work patterns as it
forced the recalculation on many common actions such as bus expansion.
This caused it to actually feel slower than with the pressure relief
valve off.
For most schematics, realtime is now fast enough to not need the valve
and for those that are extremely complex, removing the valve helps this
run more predictably
This will make it possible to maintain sheet instance information when
copying and pasting from any sheet other that the root sheet of a
project.
Setting and getting sheet page numbers must now be performed using a
sheet path. This was done to ensure that the instance paths were not
getting changed unexpectedly from different code paths.
