Use libpq's feature test macros.

As of libpq 14, libpq-fe.h defines macros for features available in its
libpq version. That means we won't be needing a `configure` check for
`PQenterPipelineMode()` after all: we can just `#ifdef` it.

Backslashes do not occur in unquoted strings. (#607)

Removes a little wart in the array/composite/range field parser.

The postgres documentation does in fact promise that if an array element is a string that contains a backslash, that element will show up in double quotes.

Overhaul array parser. Comma-separated types only. (#606)

The `array_parser` was seriously broken (#590): SQL arrays may contain elements that have a semicolon in them... _and the back-end won't put them in quotes._ The parser would always see that as a field separator. Same thing for commas in e.g. the SQL "box" type, which uses the semicolon as its separator but uses commas inside an object.

So I'm limiting `array_parser` for use with comma-separated types only, and planning a better, friendlier, faster, more flexible API for parsing arrays.

At the same time, I did manage to specialise `array_parser` internally to different encodings, which should make it considerably faster. These changes will also benefit the future array parsing API.

Bump minimum libpq/postgres to version 10. (#604)

The PostgreSQL project no longer supports postgres 9, so I'm dropping
it off the libpqxx support list as well.

The only consequence code-wise is that libpqxx will now assume that
libpq has a `PQencryptPasswordConn()`.

Actually might be nice to have a compile-time check for an acceptable
libpq version. But that's a separate project.
