fixup various places in the tree that were clearing a StringInfo by hand.
Making this function a part of the API simplifies client code slightly,
and avoids needlessly peeking inside the StringInfo interface.

this, add a 16-bit "flags" field to page headers by stealing some bits from
pd_tli.  We use one flag bit as a hint to indicate whether there are any
unused line pointers; the remaining 15 are available for future use.

This is a cut-down form of an idea proposed by Hiroki Kataoka in July 2005.
At the time it was rejected because the original patch increased the size of
page headers and it wasn't clear that the benefit outweighed the distributed
cost.  The flag-bit approach gets most of the benefit without requiring an
increase in the page header size.

their regression tests with VARSIZE/SET_VARSIZE defined to reverse byte order.

Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with
VARSIZE and VARDATA, and as a consequence almost no code was using the
longer names.  Rename the length fields of struct varlena and various
derived structures to catch anyplace that was accessing them directly;
and clean up various places so caught.  In itself this patch doesn't
change any behavior at all, but it is necessary infrastructure if we hope
to play any games with the representation of varlena headers.

parent query's EState.  Now that there's a single flat rangetable for both
the main plan and subplans, there's no need anymore for a separate EState,
and removing it allows cleaning up some crufty code in nodeSubplan.c and
nodeSubqueryscan.c.  Should be a tad faster too, although any difference
will probably be hard to measure.  This is the last bit of subsidiary
mop-up work from changing to a flat rangetable.

is still needed despite cleanups in setrefs.c, because the point is to
let the inserted Result node compute a different tlist than its input
node does.  Per example from Jeremy Drake.
