PROJ/test/unit/test_datum.cpp, branch backport-3082-to-9.0

Add DatumEnsemble::asDatum() and use it in exportToWkt()

2020-10-08T15:31:56+00:00

to allow exporting DatumEnsemble to WKT < 2019.

identify(): take into datum name aliases (fixes #1800)

2019-12-16T16:50:39+00:00

Use in API and utilities WKT2_2019 instead of WKT2_2018 (fixes #1518)

2019-09-08T09:11:03+00:00

- C API: PJ_GUESSED_WKT2_2019 is added, PJ_GUESSED_WKT2_2018 aliased to it
- C API: PJ_WKT2_2019[_SIMPLIFIED] is added, PJ_WKT2_2018[_SIMPLIFIED] alias to it
- C++ API: similarly for WKTFormatter::Convention::WKT2_2019[_SIMPLIFIED]
Those above changes should be fully backward API and ABI compatible.

projinfo changes:
- accept WKT2_2019 as value for -o switch. WKT2_2018 is still accepted (undocumented)
- output now uses 'WKT2_2019 string:', so might break scripts that would rely on that.

Other internal code references to WKT2_2018 changes to WKT2_2019, included
in tests.
