It was an unefficient adaptation of BTreeFolder2 code.

These methods have probably never been used.

getTreeIdList is still required by Folder_reindexAll.
getTreeIdList is not immediate anymore but the reindexing of a folder should
anyway be reimplemented to not depend on this method: only one tree is indexed
at a time, which is unefficient when they're small.

_getOb and similar methods are reimplemented in a faster and safer way.
It now checks it is only used to return leafs.

Similarly, _delOb now refuses to delete trees at the root.

__getattr__ wrongly returned wrapped results (__of__).

Since commit 055d0a69
("HBTreeFolder2: make object{Ids,Values,Items} really lazy"),
_fixCount() does nothing because objectIds() was optimized in a way that
len(self.objectIds()) already returns self._count()

This is required for ERP5Site_checkDataWithScript script (erp5_core BT).

And Chameleon does not workaround by lowercasing them automatically.

Lazy* classes from ZCatalog product aren't used anymore because they don't
accept iterators.

Remove objectMap* methods instead of update them because they never worked.

Add assertion to prevent passing a meta type, which was never supported
for this type of folder.

Also clean-up the comments.

readd work around for the performance regression introduced in Zope 2.12.23 in HBTreeFolder2, for the case where we use HBTreeFolder2 directly.

Otherwise, we use superclass' __contains__ implementation, which uses
objectIds, which is inefficient in HBTreeFolder2 to lookup a single key.

This commit reverts fdf4fa44 that does not work in reality.

Otherwise, we use superclass' __contains__ implementation, which uses
objectIds, which is inefficient in HBTreeFolder2 to lookup a single key.

On the way to Zope 2.12, Reform imports, specially from Globals (replacing it with Products.ERP5Type.Globals on the products that depend on ERP5Type), convert Interface uses to zope.interfaces, and remove CMFMailIn references with blessings from Jerome.
