first draft for a simple hooks based custom attribute storage,
with a BytesFileSystemStorage POC implementation.
Basically:
* a dictionary contains maps from which attribute of which entity types are
mapped to which custom storage
* hooks check for one of these entity type being added/modified/deleted
* read is based on the sql generator callback mecanism (used in vcsfile for
instance)
* all storages have the same basic interface (read, add, update, delete),
and should be pluggable in a transparent way (except at migration time
when one want to change from a storage to another)
* the sample BytesFileSystemStorage:
* may store Bytes attributes content of any entity type as file on the file system
* is based on one FSPATH rql/sql function and another _fsopen only available in sql
* has a dumb file name allocation algorithm

closes #345410: two_lines_rset, two_cols_rset, two_etypes_rset are badly named
replaced by multi_lines_rset, multi_columns_rset, multi_etypes_rset,
all taking optional 'nb' argument allowing to specify and exact count.
Bw compat is kept, usage of deprecated function updated in cw itself.
Also drop custom at_least_two_columns selector (in views.plots) since
it was the same as multi_columns_rset. Hopefuly the renaming will help
in avoid such pb...
We should now decide if we want to deprecate one_* selector in favor
of multi_*(nb=1). See note on this at then end of selectors.py
