Return the index of the operation that would be the most appropriate to
transform the specified coordinates.
This operation may use resources that are not locally available, depending
on the search criteria used by proj_create_operations().
This could be done by using proj_create_operations() with a punctual bounding
box, but this function is faster when one needs to evaluate on many points
with the same (source_crs, target_crs) tuple.

Fixes #1984
- Copy BETA2007.gsb, MD, alaska, conus, ntf_r93.gsb, ntv1_can.dat grids
from proj-datumgrid to data/tests.
- Replace a couple uses of nzgd2kgrid0005.gsb in tests by ntf_r93.gsb
- Add downsampled/subsetted versions of egm96_15.gtx as tests/egm96_15_downsampled.gtx
and ntv2_0.gsb as tests/ntv2_0_downsampled.gsb
This results in a few changes in expected results
- Simpify travis/install.sh due to less configurations to test
This results in a hopefully acceptable increase of the proj-X.Y.Z.tar.gz
from 2.9 to 5.3 MB

This commit is the result of the squashing of rfc4_dev branch in a single
commit. It implements mostly RFC 4 related work.
* Grid handling:
- remove obsolete and presumably unfinished implementation of grid catalog functionality
- all grid functionality is in grids.cpp/.hpp
- vertical and horizontal grid shift: rework to no longer load whole grid into memory
- remove hgrids and vgrids member from PJ structure, and store them in hgridshift/vgridshift/deformation structures
- build systems: add optional libtiff dependency. Must be explicitly disabled if not desired
- add support for horizontal and vertical grids in GeoTIFF, if libtiff is available
- add GenericShiftGridSet and GenericShiftGrid classes, relying on TIFF grids, that can be used for generic purpose grid-based adjustment
- add a +proj=xyzgridshift method to perform geocentric translation by grid. Used for French NTF to RGF93 transformation using gr3df97a.tif grid
- deformation: add support for +grids= for GeoTIFF grids
- horizontal grid shift: fix failures on points slightly outside a subgrid (fixes #209)
* File management:
- add a filemanager.cpp/.hpp to deal with file related work
- test for legacy proj_api.h fileapi
- proj.h: add proj_context_set_fileapi() and proj_context_set_sqlite3_vfs_name() (fixes #866)
- add capability to read resource files from the user writable directory
* Network access:
- build systems: add optional curl dependency
- add a curl-based default implementation for network related functionality
- proj.h: add C API to control network functionality, and optionaly provide network callbacks
- add data/proj.ini with default settings
- add a SQLite3 local cache of downloaded chunks
- add proj_is_download_needed() and proj_download_file()
* Use Win32 Unicode APIs and expect all strings to be UTF-8 (fixes #1765)
For backward compatibility, if PROJ_LIB content is found to be not UTF-8 or
pointing to a non existing directory, then an attempt at interpretating it
in the ANSI page encoding is done.
proj_context_set_search_paths() now assumes strings to be in UTF-8, and
functions returning paths will also return values in UTF-8.

This is invalid WKT, but GDAL 2.4 used to accept it and make a reasonable
use of it...
Currently we default it to 0 which is non sensical. Better use 1 as GDAL 2.4
did, and emit a warning.
Other fix: proj_create_from_wkt() was documented to operate by default in
non-strict validation mode, but it was actually in strict mode. So do as
documented.

arbitrary number of steps (fixes #1632)
EPSG:9103 (NAD27 to ITRF2014 (1)) is now handled.
Note:EPSG:9104 (NAD27 to ITRF2014 (2)) is not currently, since it uses
for step EPSG:8861 (NAD83(HARN) to NAD83(FBN) (1))
an unsupported transformation method (NADCON5 (3D), EPSG:1075).

In recent commits, we added a generalize_proj_crs_create_bound_vertical_crs_to_WGS84()
function, but there are situations where more accurate results can be obtained, if
instead of specifying WGS84 as the hub CRS, the user can specify the exact hub CRS.
For example the GEOID2018 grid is against NAD83(2011).
So replace this function with proj_crs_create_bound_vertical_crs()
|
|
Note: a hack has been added into customizations.sql to cancel deprecatation
of USA geoid2012 grids by geoid2018 grids, as the later are not yet available
in proj-datumgrid-northamerica (https://github.com/OSGeo/proj-datumgrid/issues/55)

proj_create_crs_to_crs(): remove elimination of Ballpark operations that caused transformation failures in some cases

ballpark steps
Currently we would discard all operations, resulting in a PJ object with
zero candidates. Better use those operations if nothing better is available.
Was seen on transforming from ETRS89 / UTM zone 31N + EGM96 height to WGS 84 (G1762).
The horizontal transformation from ETRS89 to WGS 84 (G1762) is a ballpark one.

|
With limitation of https://github.com/OSGeo/PROJ/issues/1632 regarding
concatenated operations with more than 3 steps.

proj_crs_create_projected_3D_crs_from_2D() (fixes #1587)
Also add a --3d switch to projinfo
|
|
Use in API and utilities WKT2_2019 instead of WKT2_2018 (fixes #1578)
|
|
- 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.

I've been frustrated a number of times with proj_create_crs_to_crs()
not accepting a PJ* object for the source and target CRS.
And thus constraining to go back to WKT2 in a artificial way.

When identifying an object that has already a code with authority A
but the authority of interest passed was B, then it was not checking
that A != B, and did not try to search in the objects of B.

Fixes #1301
This function takes the output PJ from proj_create_crs_to_crs(),
and add (or undo) the needed axis swap operations so that the
object returned by proj_normalize_for_visualization() has the usual
GIS axis order.
In this implementation, this does something only if the coordinate
system of the source or target CRS, geographic or projected, has
NORTH, EAST ordering.
CompoundCRS wrapping those objects are also handled.
