Wayne Stambaugh 797827b833 Fix missing legacy value and footprint field instance data.
The legacy and s-expression (prior to version 20200828) file formats only
supported symbol unit and reference fields so the newly added value and
footprint fields must be updated from the original symbol fields.

Seth Hillbrand ff54b8c718 Overplot schematic symbol fields and pins
In the absence of z-ordering, we need to ensure that pin text and symbol
fields are always visible in plots as they are in the schematic window.
We do this by overplotting the fields/pins when symbols overlap each
other.

This can be removed if/when we implement https://gitlab.com/kicad/code/kicad/-/issues/2211

Wayne Stambaugh a468a79948 Eeschema: fix broken page numbers when renaming a sheet file name.
Remove duplicate instance data saved in both root SCH_SCREEN and SCH_SHEET
objects that was causing them to be out of sync.  All sheet instance data
is stored in the SCH_SHEET object itself and rebuilt on the fly so it is
always current.

Remove Get/SetPageNumber from SCH_SHEET_PATH object so it doesn't obfuscate
where the actual sheet page number information exists.

Wayne Stambaugh 7a00e01b3e Eeschema: fix false positive library symbol changed ERC errors.
This fix required sorting all of the LIB_PART draw items to ensure
accurate comparison between the symbols stored in the schematic and the
original library symbols.  This has a noticeable impact on symbol library
load performance.  It may also cause significant changes the next time
the library is saved due to changes in the draw item sorting.  Hashing
may be a better solution here but this addressed the immediate problem.

A skeleton method SCH_SCREEN::SwapSymbolLinks() was added because there
is most likely an issue with orphaned symbols in the schematic library
symbol cache during undo/redo operations.  More testing is required to
verify this.

Seth Hillbrand f73039cb18 Fix wire endings both too small and too large
Junctions should only be wire endings when ending directly on the wire.
This is the requirement for netlisting, so we need to follow it in the
auto-end as well.

SCH_LABEL needs to allow ending because any wire that touches the label
will be connected, so there's a use case for this.  However, the
bounding box for local labels did not include their connection point, so
we increase that box a bit.  Note that this might have the opposite
effect to https://gitlab.com/kicad/code/kicad/-/issues/7689

Mikolaj Wielgus 8eca23aabe Mark null project initial screen as zoom-initialized
The variable `m_Initialized` in `BASE_SCREEN` is used by
`SCH_EDIT_FRAME` to mark whether a screen had its zoom level initialized
by the "zoom to fit screen" action. When this variable is `false`, the
function `SCH_EDIT_FRAME::DisplayCurrentSheet()` performs "zoom to fit
screen", modifying the zoom level. This function is indirectly called in
the undo routines, so if `m_Initialized` is not set to `true`, a zoom
change will occur when the user undoes an operation, a behavior that is
undesired.

`m_Initialized` was not initialized to `true` for the null schematic
(the schematic that is loaded if no project is loaded), causing the
aforementioned undesired behavior.

To prevent this, I've changed the `SCH_EDIT_FRAME` constructor to set
`m_Initialized` to `true`, since it zooms to fit screen already. I've
moved `m_Initialized` from `BASE_SCREEN` to `SCH_SCREEN`, as it is used
only in Eeschema, and renamed it to `m_zoomInitialized`, a name I
believe that better describes what this variable does.

I've also introduced the function `SCH_EDIT_FRAME::initScreenZoom()` to
group the "zoom to fit screen" action with setting `m_Initialized` to
`true`, as they often should occur together.

I'd also like to say that I'm not confident whether
`SCH_EDIT_FRAME::DisplayCurrentSheet()` should perform the zoom level
initialization at this point, but I have decided to not change this
behavior for now, as the commit history suggests it's several years old.

Wayne Stambaugh 169f63a6c0 Eeschema: make schematic sharing truly safe across all designs.
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.

Wayne Stambaugh 7183e9f97e Make the new schematic and symbol library file formats the default.
This is a very large and potentially disruptive change so this will be an
unusually long and detailed commit message.

The new file formats are now the default in both the schematic and symbol
library editors.  Existing symbol libraries will be saved in their current
format until new features are added to library symbols.  Once this happens,
both the legacy schematic and symbol file formats will be no longer be
savable and existing libraries will have to be converted.  Saving to the
legacy file formats is still available for round robin testing and should
not be used for normal editing.

When loading the legacy schematic file, it is imperative that the schematic
library symbols are rescued and/or remapped to valid library identifiers.
Otherwise, there will be no way to link to the original library symbol and
the user will be required manually set the library identifier.  The cached
symbol will be saved in the schematic file so the last library symbol in
the cache will still be used but there will be no way to update it from the
original library.

The next save after loading a legacy schematic file will be converted to
the s-expression file format.  Schematics with hierarchical sheets will
automatically have all sheet file name extensions changed to .kicad_sym
and saved to the new format as well.

Appending schematics requires that the schematic to append has already been
converted to the new file format.  This is required to ensure that library
symbols are guaranteed to be valid for the appended schematic.

The schematic symbol library symbol link resolution has been moved out of
the SCH_COMPONENT object and move into the SCH_SCREEN object that owns the
symbol.  This was done to ensure that there is a single place where the
library symbol links get resolved rather than the dozen or so different
code paths that previously existed.  It also removes the necessity of the
SCH_COMPONENT object of requiring any knowledge of the symbol library table
and/or the cache library.

When opening an s-expression schematic, the legacy cache library is not
loaded so any library symbols not rescued cannot be loaded.  Broken library
symbol links will have to be manually resolved by adding the cache library
to the symbol library table and changing the links in the schematic symbol.

Now that the library symbols are embedded in the schematic file, the
SCH_SCREEN object maintains the list of library symbols for the schematic
automatically.  No external manipulation of this library cache should ever
occur.

ADDED: S-expression schematic and symbol library file formats.
