To keep things moving: I assume this is unacceptable. So v10 redirects
every access to a PGconn struct member through a shim, similarly to
how conn->errorMessage was translated in v9. This adds plenty of new
boilerplate, but not a whole lot of complexity. To try to keep us
honest, libpq-int.h has been removed from the libpq-oauth includes.

This will now handle in-place minor version upgrades that swap pg_conn
internals around, so I've gone back to -MAJOR versioning alone.
fe_oauth_state is still exported; it now has an ABI warning above it.
(I figure that's easier to draw a line around during backports,
compared to everything in PGconn. We can still break things there
during major version upgrades.)
