  1. Remove FormData_pg_sequence_data from init_params()/sequence.c 

    init_params() sets up "last_value" and "is_called" for a sequence, based
on the sequence properties in pg_sequences.  This simplifies the logic
around log_cnt, which is reset to 0 when the metadata of a sequence is
expected to start from afresh when its properties are updated.

  2. Integrate addition of attributes for sequences with ALTER TABLE 

    This is a process similar to CREATE OR REPLACE VIEW, where attributes
are added to a sequence after the initial creation of its Relation.
This gives more flexibility to sequence AMs, as these may want to force
their own set of attributes to use when coupled with their computation
methods and/or underlying table AM.

  3. Refactor code for in-core "local" sequences 

    This commit restructures the code of in-core sequences into a new set of
files:
- seqdesc.c is renamed to seqlocaldesc.c.
- seqlocalxlog.c to the code in the WAL replay logic.
- seqlocalam.c to store a set of routines called from sequence.c,
finishing the separation between the main sequence logic and the in-core
sequences.
- seqlocalam.h to store the AM-specific structures and routine related
to the in-core sequences.

WAL records are renamed to "SequenceLocal" with structures, variables
and file structures mapping to that.

  4. Sequence access methods - backend support 

    The "seqlocal" sequence AM is now plugged in as a handler in the
relcache, and a set of callbacks in sequenceam.h.

  7. snowflake: Add sequence AM based on it 

    This includes documentation and a basic implementation, though this is
in a very early stage.
