Robert Haas 694e3d139a Further code review for pg_lsn data type.
Change input function error messages to be more consistent with what is
done elsewhere.  Remove a bunch of redundant type casts, so that the
compiler will warn us if we screw up.  Don't pass LSNs by value on
platforms where a Datum is only 32 bytes, per buildfarm.  Move macros
for packing and unpacking LSNs to pg_lsn.h so that we can include
access/xlogdefs.h, to avoid an unsatisfied dependency on XLogRecPtr.

Robert Haas 844a28a9dd pg_lsn macro naming and type behavior revisions.
Change pg_lsn_mi so that it can return negative values when subtracting
LSNs, and clean up some perhaps ill-considered macro names.
