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).
(cherry picked from commit b41d446f58)
We're going to use the dataStore to update the symbol, so
if we store resolved values it will nuke any text variables
even if the field wasn't edited.
Not sure if the BOM generator has a separate resolve-variables
step or not. But it will need one as the code removed here
only worked for Values and Footprint fields anyway.
- 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.

Previously, bus elements that were not instantiated as individual nets
could not connect to each other. This caused issues for complex
schematics where busses needed to connect to other busses with elements
that resolved to the same net names. Functionally, this means mixing
bus elements, which we will replace with first-class elements in version
8 but currently can only be accomplished either by using bus aliases and
this patch or by individually instantiating each bus element as a
local label

(cherry picked from commit 16b4ec3c7e)
The list of candidates (names) must be restricted to existing global labels
and symbols creating a global net name: power symbols having only one power
input pin (a power output does not create net name).
