Current behavior:
Auto-generated SQL fails with ERROR: missing FROM-clause entry for table when table alias names exceed the target length of 63 characters. This is because odoo.osv.expression.py handles shortening the table name alias in generate_table_alias, but not in get_join_conditions. In the resulting SQL, shortened aliases are used in the FROM clause, whereas in the join conditions, the full alias is used, which is both exceeding the Postgres limit and not matching the table name alias in the FROM clause.
Expected behavior:
auto-generated SQL runs without errors.
Implementation of fix:
- refactor alias shortening into new function _shorten_alias to make it reusable
- Use _shorten_alias in both generate_table_alias and get_join_conditions

By adding a parameter `_table_query` on the Model, we can now have views
that depend on the context. The query is used instead of the table name
in ORM operations. This allows to pre-compute some values to improve
performance, instead of storing context values in the database.

Introduce better methods for introducing tables, join clauses and where
clauses to the Query object, and other methods to generate a complete
SELECT query. The Query object can also behave as a tuple of ids, where
the query is made on demand, and the result is memoized.
Instead of merging Query objects (main domain and access rules domains),
which requires renaming aliases in query strings, make `expression` push
its result in an existing Query object. This removes tricky code.
This also avoids using `IrRule.domain_get()`, which has become unsafe,
since it returns a list of tables (for the FROM clause) which does not
include the joins from the generated Query object.
