* Adding failing test for base table aliases using SQLSelect
* FIX Retain table aliases applied to the base table on queries
* FIX Move the trimmed alias outside of the condition so we can use it within the condition
* BUGFIX many many through not sorting by join table
* #8534 added docs to support many many sorting fix
* #8534 added test cases for many_many default sorting
This makes it easier to swap one fo the other without code breaking.
Since it’s strictly a removed API, I’ve opted to throw a deprecation
note in SS4 rather than throwing an InvalidArgumentException.
Fixes#2949
Note that the medium date format depends on locale, with en_NZ being
resolutely numeric. I’ve updated the test to verify a couple of locales
to make this more obvious.
Fixes#8121
The SS4 behaviour of limit=0 is unlikely to be the SS5 behaviour.
To clear the limit limit=null is recommended.
In addition, there’s a bit tighter type maintenance in the internal
limit data (ensure things are int).
Fixes#2950.
* NEW: Add Hierarchy::prepopulate_numchildren_cache()
API: Hierarchy::stageChildren() customisations must be applied to the base class and not include record-specific behaviour.
Adds the ability to prepopulate the cache for Hierarchy::numChildren()
in a batch.
Note that this optimisation means that stageChildren() is not called on
each record in order to calculate numChildren(). This means that the
structure of the stageChildren() query must be the same for all records
and the behaviour cannot be customised only for a subclass of the base
data class. For example, apply your customisations to SiteTree and not
a subclass.
This is an useful part of optimising the query count on tree generation.

* NEW: Add Hierarchy::prepopulateTreeDataCache()
This provides a more extensible way of preopulating caches for optimised
tree generation.
Fixes https://github.com/silverstripe/silverstripe-framework/issues/8391
When selecting a column, it doesn't make sense to have it distinct.
As an alternative, the API could be changed to give the end user the option
(eg `->column($field, $distinct = false)`)
However if we did that, we would need to make sure we do something
similar with `SilverStripe\ORM\UnsavedRelationList` to ensure consistency.
