Fixed #21840 -- Moved dunder methods from SimpleLazyObject to LazyObject...

Thanks bmispelon for the suggestion.

The test previously failed with the error:
(1170, "BLOB/TEXT column 'name' used in key specification without a key length")

Some platforms with os.name == 'posix' do not have the
fcntl module, e.g. AppEngine.

refs #19373.

Fixed #21989 - Modified first day of week in AU locale.

Although Australia is a signatory to ISO 8601, there's a lot of evidence to suggest that this is in the same category as "officially, the USA uses metric". See the ticket for supporting details.

db_parameters should respect an already existing db_type method and
return that as its type string. In particular, this was causing some
fields from gis to not be generated.

Thanks to @bigsassy and @blueyed for their work on the patch.

Also fixed #22260

Changed start of week for Australia to Sunday as requested in https://code.djangoproject.com/ticket/21989

Thanks to trac user merb for the report.

Thanks Jeroen Pulles for the report and Simon Charette for the review.

Hooks are quantum; you can not have an amount of them.

Since d2e242d16c6dde6f4736086fb38057424bed3edb made isinstance()
calls work correctly on LazyObject, we can simplify the
implementation of is_local_storage added in
7e27885c.

This commit also added tests for LazyObject and refactored
the testsuite of SimpleLazyObject so that it can share
test cases with LazyObject.

This seems worthwhile in its own right, but also works around an Oracle
bug (in versions 10 -- 11.1) where the use of Unicode would reset the
date/time formats, causing ORA-01843 errors.

Thanks Trac users CarstenF for the report, jtiai for the initial patch,
and everyone who contributed to the discussion on the ticket.
