Add ALTER SEQUENCE to modify min/max/increment/cache/cycle values

Also updated create sequence docs to mention NO MINVALUE, & NO MAXVALUE.

New Files:
doc/src/sgml/ref/alter_sequence.sgml
src/test/regress/expected/sequence.out
src/test/regress/sql/sequence.sql


ALTER SEQUENCE is NOT transactional.  It behaves similarly to setval().
It matches the proposed SQL200N spec, as well as Oracle in most ways --
Oracle lacks RESTART WITH for some strange reason.
