Provides for better code readability, but mainly this is infrastructure changes
to allow further changes such as arbitrary footers on printed tables.  Also,
the translation status of each element in the table is more easily customized.

> * -Improve dead row detection during multi-statement transactions usage

There are two ways to track a snapshot: there's the "registered" list, which
is used for arbitrary long-lived snapshots; and there's the "active stack",
which is used for the snapshot that is considered "active" at any time.
This also allows users of snapshots to stop worrying about snapshot memory
allocation and freeing, and about using PG_TRY blocks around ActiveSnapshot
assignment.  This is all done automatically now.

As a consequence, this allows us to reset MyProc->xmin when there are no
more snapshots registered in the current backend, reducing the impact that
long-running transactions have on VACUUM.

not which one we had before (that worked, and thus is completley irrelevant)

unnecessary #include lines in it.  Also, move some tuple routine prototypes and
macros to htup.h, which allows removal of heapam.h inclusion from some .c
files.

For this to work, a new header file access/sysattr.h needed to be created,
initially containing attribute numbers of system columns, for pg_dump usage.

While at it, make contrib ltree, intarray and hstore header files more
consistent with our header style.

output column are not emitted.  (That change already caused more noise in
the regression test output files than I would like.)  Provide some needed
editorial help for comments, clean up code formatting.

as those for inherited columns; that is, it's no longer allowed for a child
table to not have a check constraint matching one that exists on a parent.
This satisfies the principle of least surprise (rows selected from the parent
will always appear to meet its check constraints) and eliminates some
longstanding bogosity in pg_dump, which formerly had to guess about whether
check constraints were really inherited or not.

The implementation involves adding conislocal and coninhcount columns to
pg_constraint (paralleling attislocal and attinhcount in pg_attribute)
and refactoring various ALTER TABLE actions to be more like those for
columns.

file is deleted too early when starting the recovery of a warm standby server.

Also add a sanity check in pg_standby so that it will refuse to delete anything
earlier than the file being restored, and improve the debug message in case
nothing is deleted.
