ADDED a new pin electrical type "free" for internally unconnected pins.
CHANGED the "unconnected" pin electrical type is now represented by
"no_connect" in files and netlists. (The legacy syntax is also accepted
in files.)
This way the net names can be inspected in eeschema and cross-probing works.
Testcases updated for the name changes
CHANGED: all unconnected pins are now included in the netlist with no_connect_ prefixes
In particular, there was a typo that kept library values from being
updated, and there was missing logic to fetch the various field names
from the library parts (and the change-to part).
Also implements some performance gains by desisting from copying
LIB_FIELDs around every time we want to look at them.

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.

This provides a method to add symbols that represent footprints on the
board that do not have an associate component such as mounting holes,
fiducials, logos, etc that should be excluded from the bill of materials.
It also prevents those footprints from being removed from the board
accidentally when updating the board from the schematic.
ADDED: Support to exclude schematic symbols from bill of materials
export.
CHANGED: All mandatory fields in derived symbols can be edited. This
not only includes the field value but also all text properties.
Kill the dual datasheet variable storage which caused many datasheet
bugs over the years. The datasheet is now always stored in the data
sheet field.
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.
