Fixed #23576 -- Implemented multi-alias fast-path deletion in MySQL backend.
...
This required moving the entirety of DELETE SQL generation to the
compiler where it should have been in the first place and implementing
a specialized compiler on MySQL/MariaDB.
The MySQL compiler relies on the "DELETE table FROM table JOIN" syntax
for queries spanning over multiple tables.

Fixed #30856 -- Combined fast-delete queries by model during cascade deletion.
...

Fixed #30191 -- Selected only referenced fields during cascade deletion.
...
The non-referenced fields can only be deferred if no deletion signals
receivers are connected for their respective model as connected as these
receivers might expect all fields of the deleted model to be present.
Thanks Ed Morley for the report.

Renamed Field.rel attribute to remote_field
...
Field.rel is now deprecated. Rel objects have now also remote_field
attribute. This means that self == self.remote_field.remote_field.
In addition, made the Rel objects a bit more like Field objects. Still,
marked ManyToManyFields as null=True.

Fixed #16426 -- deletion of 1000+ objects with relations on SQLite
...
SQLite doesn't work with more than 1000 parameters in a single query.
The deletion code could generate queries that try to get related
objects for more than 1000 objects thus breaking the limit. Django now
splits the related object fetching into batches with at most 1000
parameters.
The tests and patch include some work done by Trac alias NiGhTTraX in
ticket #21205 .
