Peter Eisentraut 964d01ae90 Automatically generate node support functions 
Add a script to automatically generate the node support functions
(copy, equal, out, and read, as well as the node tags enum) from the
struct definitions.

For each of the four node support files, it creates two include files,
e.g., copyfuncs.funcs.c and copyfuncs.switch.c, to include in the main
file.  All the scaffolding of the main file stays in place.

I have tried to mostly make the coverage of the output match what is
currently there.  For example, one could now do out/read coverage of
utility statement nodes, but I have manually excluded those for now.
The reason is mainly that it's easier to diff the before and after,
and adding a bunch of stuff like this might require a separate
analysis and review.

Subtyping (TidScan -> Scan) is supported.

For the hard cases, you can just write a manual function and exclude
generating one.  For the not so hard cases, there is a way of
annotating struct fields to get special behaviors.  For example,
pg_node_attr(equal_ignore) has the field ignored in equal functions.

(In this patch, I have only ifdef'ed out the code to could be removed,
mainly so that it won't constantly have merge conflicts.  It will be
deleted in a separate patch.  All the code comments that are worth
keeping from those sections have already been moved to the header
files where the structs are defined.)

*
* NOTES
* Path nodes do not have any readfuncs support, because we never
* have occasion to read them in. (There was once code here that
* claimed to read them, but it was broken as well as unused.) We
* never read executor state trees, either.
*
* Parse location fields are written out by outfuncs.c, but only for
* debugging use. When reading a location field, we normally discard
* the stored value and set the location field to -1 (ie, "unknown").
* This is because nodes coming from a stored rule should not be thought
* to have a known location in the current query's text.
* However, if restore_location_fields is true, we do restore location
* fields from the string. This is currently intended only for use by the
* WRITE_READ_PARSE_PLAN_TREES test code, which doesn't want to cause
* any change in the node contents.
