Malcolm Tredinnick 90279aeaf0 Fixed #8575 -- Catch one particular instance of OperationalError in MySQL and
convert it to an IntegrityError, which seems like the more natural case (and is
consistent with other backends). This makes exception handling in Django much
easier.

The solution is extensible for any other error codes we may wish to add going
forwards.

closer examination of the C-library layer.

Malcolm Tredinnick 6294fc7179 Changed "exact" matches in MySQL to use the database's native collation.
This effectively reverses the change in [7798]. It was proving too difficult to
successfully manage all the side effects here and provide a satisfactory
solution for everybody. Many thanks to arne, Martin von Löwis and, particular,
Karen Tracey, for doing a lot of research and proto-patches here to establish what was possible and practical.

This is backwards incompatible if you were relying on the behaviour after
[7798]. The docs have been updated to indicate the solution.

Refs #2170, #7789, #8102.

if-tests in django.db.models.fields.

This is a backwards incompatible change if you were relying on 'exact' being

Malcolm Tredinnick ba010ec1c0 Made some types of nested update queries very slightly more efficient at the
database level. Also worked around the fact that MySQL (and maybe other
backends we don't know about) cannot select from the table they're updating.

created (inline "REFERENCES" are ignored by InnoDB, unfortunately).

Also converted all management.py CREATE TABLE statements to use db_type(), which made that code cleaner. The Field.get_internal_type() hook still exists, but we should consider removing it at some point, because db_type() is more general. Also added docs -- the beginnings of docs on how to create custom database Field classes. This is backwards-compatible.
