ab97eaaf15 use deck tree for new/review count calculation
- wins back the performance lost by the decks and dconf not being
in memory, and the overhead of serializing data for DB calls
- card counts are no longer capped to 1000
- learn counts are currently still calculated separately - can't merge
v1 counts without changing the existing behaviour
- partially rendering the tree may yield more savings

- changes are now committed in bulk when closing the dialog,

- it's not necessary to save the note to the database to preview it
- duplicate fields are now shown as duplicates in the top list
- redraw preview more quickly
- use + instead of _ when deduplicating names, as the latter is a
glob character

6b4a40f774 catch schema mod in background
If the schema confirmation dialog is shown on a background thread it
will crash the app, so we convert this to an assertion error that gets
caught by the error handler. Code still needs to be updated to modify
the schema prior to moving to the background, but at least this way
it doesn't crash.

2641862b56 update fields and models diags
- field changes are now applied when user closes dialog with save

- models diag now fetches note type and saves it as required, instead
of holding on top a copy that can grow stale as changes are made in
subdialogs
- both dialogs now perform operations in the backend
- note.model() now fetches the note type on the fly, instead of
holding on to a copy that may become stale

6350e18680 hook up new note and note type handling
- notetypes are fetched from the DB as needed, and cached in Python
- handle note type changes in the backend. Multiple operations can now
be performed in one go, but this is not currently exposed in the GUI.
- extra methods to grab sorted note type names quickly, and fetch by
name
- col.models.save() without a provided notetype is now a no-op
- note loading/saving handled in the backend
- notes with no valid cards can now be added
- templates can now be deleted even if they would previously
orphan notes

a number of fixmes have been left in notes.py and models.py

94c284724f mw.debug_diag is the dialog and not the window
This will allow, for example, for add-ons to do self.debugDiag.text
and access the debugger text. I see very little reason to have a
direct access to the dialog window.

I should note that self.debugDiag is never used anywhere in the code,
so I think it should be deleted; unless you've heard of some add-on
using it.

be1904ba1d Fixed build-mo-files not failing the build when msgmerge
is not found:
https://github.com/ankitects/anki/runs/617116053?check_suite_focus=true#step:27:1244

The build was not falling because when you do `(commands)` in a
shell script, the `set -e` directive is not inherited. Then, either
do not start a new shell or just use an if to test the error condition.
