https://github.com/OSGeo/PROJ/pull/2536 changed the name of the
ellps=intl to "International 1924 (Hayford 1909, 1910)"
When writing a GeoTIFF file from GDAL using a SRS built from a
PROJ string, GDAL massages the datum name to
"Unknown_based_on_International_1924_Hayford_1909_1910_ellipsoid"
Before this fix, this wasn't considered as equivaleent to the non-massaged
datum name "Unknown based on International 1924 (Hayford 1909, 1910) ellipsoid"
Use in API and utilities WKT2_2019 instead of WKT2_2018 (fixes #1518) 2019-09-08T09:11:03+00:00 Even Rouault even.rouault@spatialys.com 2019-09-04T13:46:13+00:00 024f63731283c0026ad5b4dea4084bc48bbcc6f7 - 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.

This work mostly consists of:
- a C++ implementation of the ISO-19111:2018 / OGC Topic 2
  "Referencing by coordinates" classes to represent Datums,
  Coordinate systems, CRSs (Coordinate Reference Systems) and
  Coordinate Operations.
- methods to convert between this C++ modeling and WKT1, WKT2
  and PROJ string representations of those objects
- management and query of a SQLite3 database of CRS and Coordinate Operation definition
- a C API binding part of those capabilities

This is all-in-one squashed commit of the work of
https://github.com/OSGeo/proj.4/pull/1040
