This fulfills the goal of searching and fetching fields in a single SQL
query. We introduce the new method search_fetch() for that purpose.
Also introduce method fetch() to fetch some fields for a recordset if
they are not in cache yet.
The call graph is as follows:
search() calls search_fetch()
search_read() calls search_fetch() and _read_format()
read() calls fetch() and _read_format()
search_count() calls _search()
search_fetch() calls _search() and _fetch_query()
fetch() calls _search() and _fetch_query()
The methods _search() and _fetch_query() are usually the ones to
override to implement business-specific logic. The method _search()
returns a Query object to retrieve the records that satisfy the given
domain and are accessible for reading. The method _fetch_query() uses a
Query object to retrieve fields from the database and store them in
cache.
Also use search_fetch() to save one query in search_read() and the
reading of one2many fields.
