Allows for safe migration to another id generator, by preventing silent
success of any piece of code still using the former generator, allowing
its detection and resolution before duplicate ids are emitted.
As a consequence, also allows on-demand and partial migration of id
generators.

Also, avoid a few single-use variables.
Also, use modern exception raising syntax.

Previous code was broken since BT revision are not integers anymore.

the code of some id generator can raise ValueError when objects
are not fully installed, and this is typically a case when the
compatibility code needs to run (like uid generation in the middle
of the installation of id generators objects)

- add the id generators generic
- add the zodb continuous increasing id generator
- add the sql non continuous increasing id generator
- change id tool for the id generators and the compatiblity with the old api
- change the business template to not modify the generator dictionaries
  during the export and the install of bt
- change the test of id tool

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.

Simplification: set default to 0 if not set, which removes the need for Dummy class instance, and factorises 2 branches of a test.
Micro optimisation: fetch the persistent mapping only from self only once (prevents instanciating 2 acquisition wrappers out of 3).
Improve coding style (space around operators).

It is pointless to instantiate a lock as a local value, as function local values are local to any given call, hence local to a thread.
Moreover, there is no need to lock access to a persistent object, as its access is protected by ACID.

Add a method on IdTool to dump all ids from table and store them in ZODB (persistent mapping on portal_ids).
Call that method before clearing catalog.

Move all code relative to dict_length_ids in a code which access is controled by "store" value. This prevents portal_ids' persistent object modifications when "store" is false.

Make default value None. Previous code had a bad behaviour if the default value was a long (it should be valid, but isinstance(long, int) is obviously False, so default fell back to "1"). Anyway, if default is an invalid value, ZSQLMethod will complain.
