Release 17 of the PostgreSQL Buildfarm Client

I have pushed Release 17 of the PostgreSQL Buildfarm client.

Release 17 has two main features:

* Modernize the way we do cross-version upgrade tests. Most of the
logic for modifying instances to make them suitable for cross
version upgrade testing has now been migrated to the Postgres core
code in |src/test/perl/PostgreSQL/Test/AdjustUpgrade.pm|. The new
code simply imports this module and leverages its knowledge.
* Support of building with |meson|. This is only supported on version
16 or later of Postgres, older branches will continue to use the
older toolsets. To enable building with |meson|, there are several
new settings, illustrated in the sample configuration file:
o |using_meson| this must be set to a true value
o |meson_jobs| this controls the degree of parallelism that
|meson| will use
o |meson_test_timeout| this is used to multiply the meson test
timeout. The default is 3, 0 turns off timeout
o |meson_config| This is an array of settings for passing to
|meson setup|. Note that all options need to be explicitly given
here - the client disables all |auto| options. This includes use
of |zlib| and |readline|, which do not default to on, unlike
|autoconf| setups.

There are also a number of relatively small bug fixes and tweaks (e.g.
some improvements in processing typedefs).

The release is available at
<https://github.com/PGBuildFarm/client-code/releases> or
<https://buildfarm.postgresql.org/downloads/latest-client.tgz>

Enjoy!

cheers
