Change nextval and other sequence functions to specify their sequence
argument as a 'regclass' value instead of a text string. The frontend conversion of text string to pg_class OID is now encapsulated as an implicitly-invocable coercion from text to regclass. This provides backwards compatibility to the old behavior when the sequence argument is explicitly typed as 'text'. When the argument is just an unadorned literal string, it will be taken as 'regclass', which means that the stored representation will be an OID. This solves longstanding problems with renaming sequences that are referenced in default expressions, as well as new-in-8.1 problems with renaming such sequences' schemas or moving them to another schema. All per recent discussion. Along the way, fix some rather serious problems in dbmirror's support for mirroring sequence operations (int4 vs int8 confusion for instance).
