Jeff Young 38906397d2 Move V6->V7 sim model migration from sheets to screens.
Also moves passive RLC inference out from migration to just-in-time
creation for the simulator or netlisting.

Also fixes a version guard mismatch because the spice migration was
done inside UpdateSymbolInstances (which has its own version guard).

Also changed UpdateSymbolInstances to UpdateSymbolInstanceData so
someone else in the future doesn't think it's a general-purpose symbol
instance updater.

Wayne Stambaugh 5001555f0e Fix crash in Altium schematic importer.
The crash was caused by an unhandled exception. The uncaught exception
caused a cacophony of null configuration setting pointers so guards were
added to prevent crashes should other exceptions occur that do not get
handled correctly.

Wayne Stambaugh 4a27d856f7 Move schematic sheet instance information into file sheet definition.
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.

Wayne Stambaugh a11c40197f Expunge default symbol instance from schematic file format.
Now that importing hierarchical sheets "properly" imports instance data,
the default symbol instance setting doesn't have any meaning.

Wayne Stambaugh 2b387ae9c3 Move schematic symbol instance data back into symbol definition.
This change reverts the storage of all symbol instance data in the root
schematic.  This was done because it's not possible to reuse instance
data when importing from sub-sheets.

There has been a fundamental change in how sheet paths are store in the
instance data.  The root schematic UUID is always used when saving the
instance data.  To prevent file churn, the virtual root sheet UUID is set
to the root schematic UUID when loading the project.  This provides a way
to determine the project that stored the instance data.  All uses of paths
without root sheet have been expunged from the code.

The sheet instance data is still saved only in the root sheet for the
time being.  New sheet instances will be automatically assigned an page
number based on the incremental virtual sheet page number.  Sheet page
numbers will not be imported.

Added project name to instance data to improve the readability of the
schematic file format.  It also creates an opportunity to remove orphaned
instance data by project name rather than cryptic UUIDs.

The commit bumps the schematic file format version in order to fix the

It also sets the initial instance data to undefined in the SCH_SYMBOL
ctor so on the first schematic save, the default instance will be set
to the first instance of the symbol.

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.

jean-pierre charras eb7dc6ddd9 Minor fixes. In stand alone show the frame as soon as possible.
Especially when running Pcbnew to open a complex board the frame is shown faster.
Add also a busy cursor when loading files and building the data.
