Per the checklist in RELEASE_CHANGES for the creation of a new stable
branch, this commit does the following things:
- Arm gen_node_support.pl's nodetag ABI stability, based on the contents
of nodetags.h.
- Update URLs of top-level README and Makefile to point to the new
stable version.
In passing, this fixes an incorrect comment in release-17.sgml.
Presently, one of the lines in README.md has trailing whitespace,
which was added by commit 363eb05996 to maintain a line break that
was in the non-Markdown version. Instead of changing
.gitattributes, let's match this paragraph's style with the style
of the following paragraph, thereby removing the trailing
whitespace.

This is a first step toward modernizing our README file. Some
popular developer platforms support rendering README.md files, so
a direct conversion to Markdown seems like a good place to start.
The intent is to keep this file legible as plain text even as it
accumulates more content.
