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) 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.
Also improves the SNR and consistency of the menu item text. For
instance, a position is rarely useful, while relative sizes can be.
Also removes some unnecessary repitition, such as "Graphic Rectangle"
when "Rectangle" communicates the necessary information.
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.)

Cross-probing from Pcbnew to Eeschema revealed that EEschema was
including all fields, visible or not, when calculating the bounding
box of the probed componentt. This caused problems with long strings
such as URLs that were not set as visible. The cross-probing code
tries to minimize 'Zoom to Fit' operations when it's not necessary,
and the overly large bbox values often resulted in zooms not being
performed and components displayed very small.
This code adds a version of 'GetBoundingBox' that takes a boolean
to tell it to include invisble fields or not.

Remove extraneous use of FLAG0 from tracks cleaner (it was checked but
never set).
Fix issue in expand connections where two parts of it couldn't agree
on the same flag (BUSY vs SKIP_STRUCT), and where the second part was
clearing the flag instead of setting it.
Remove obsolete HIGHLIGHT infrastructure (we now use selection).
Remove extraneous use of BUSY flag in several places (it was never
set).
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.
Every time SCH_COMPONENT::GetDrawItem() was called, the schematic symbol
pin table was updated. Under certain conditions, this happens inside
loops so the amount of time spent rebuilding the pin table can add up.
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.
