Added cast from varchar, bpchar, name
Note that bpchar (i.e. the output format for "char" - with quotes) and
name are always decoded, even if the db is SQL_ASCII, because these
types are mostly used in system catalogs and there should be no such
crap as unencded data there.

Dropped ArrayCaster, expose register_array function instead
The function only associates array_oid -> base_oid. Looking up the right
typecaster happens at cast time: this way composite adapters (record,
list) can use the caster register in the right context.
All the types for which there is an adapter gets an array caster now.

Really use the context to transform components types
It works for arrays and records, except for text arrays because the
decorator registers the TypeCaster directly, not the oid. This must
change, we need a different decorator/registration.

The Transformer is an adaptation context
Dropped cursor from Adapter, TypeCaster, Transformer. Added adapters and
casters map on Trasformer.

customized now composite types containing that type use the same
customization. Also fixed a circular reference between transformer and
cursor.
