Warnings are handled with the other logs (and not always sent to stderr),
they also appear under a module __name__ channel instead of py.warn.
The disadvantage is that there is no longer specific warnings,
such as pending deprecation warning or deprecation warning.

Each OpenERP cursor is mapped to a single psycopg2 connexion.
When a cursor is closed, the connexion is pushed back to a
pool and reused later. Now that the 'snapshot isolation' level
is used, the fact we didn't properly commit/rollback a
transaction appears: some 'concurrent' update showed up.
The fix is simple: whenever a cursor is closed, we rollback
any pending operation (which is the expected behavior).
(Furthermore, the connexion is explicitely closed when the
connexion is pushed back but not kept in the pool.)

In the context of OpenERP transaction, we really need the
'snapshot isolation' level provided by PostgreSQL because
not being able to make repeatable reads within the same
transaction is a very dangerous source of corrupted data,
especially in a very concurrent system.
The performance impact of switching from the default
read_committed level to serializable/repeatable_read level
has been measured and and was not distinguishable from
the standard deviation - so it seems quite acceptable.
User of PostgreSQL 9.1 might want to update to psycopg2
version 2.4.2 or later to properly use the regular
snapshot isolation level, and not the newer, more
expensive serializable level (see comments in Cursor
docstring).

- openerp.pooler no longer provides get_db_only, which is a provided by sql_db
- openerp.sql_db does not rely anymore on netsvc, which is goog as it was
making a circular import. The downside is that db_close callers have to clean
also the Agent themselves.

- Some logging code moved from netsvc.py to loglevels.py
- Changed imports to use the new openerp module
- config and netsvc initialization calls move to openerp-server.py
- Moved openerp-server.py outside the old bin directory
- Some imports in tools moved inside the methods to break mutual-dependencies
