* DOC: Refresh Development/Quickstart and remove Development/Threads
The document Development/Threads was severely out of date, and was
focussed on contrasting the current API with an old API that was
deprecated several years ago, and removed from the current PROJ earlier
this year.
Update Development/Quickstart to give more information about the use of
threading context, as a replacement for the content that was previously
in Threads.
Also give the example code examples/pj_obs_api_mini_demo.c a cleanup
pass to make it at least internally consistent with its own code style.
The header comments of the example code are still, much like the Threads
document, fixated on comparing proj.h against proj_api.h, which is an
interesting historical curio to be sure, but probably doesn't need to
persist here. It might be worth cleaning this up further as a separate
exercise.
Fixes #2451

Removes proj_api.h from the public API. The contents of the header file
has been moved to proj_internal.h verbatim and any references to
proj_api.h has been changed to proj_internal.h.
The documentation of proj_api.h has been removed. The only exception to
this is the API migration guides which still mention the old API.

Those changes are also compatible with Sphinx 2.x
The use of .. cpp:enumerator:: for a C enum is questionable,
but .. c:member:: no longer works in Sphinx 3 for the value of
a C enum, but .. c:enumerator:: is Sphinx 3 only
( https://www.sphinx-doc.org/en/master/usage/restructuredtext/domains.html#directive-c-enumerator )
Sphinx 3 is also more strict with the use of cross-reference
to C types. It rejects cross-references to things like
`` :c:type:`int` `` since this isn't a type we actually define.

proj_context_get_user_writable_directory to proj.h (#2162)
Fixes #2028
|
|
Equivalent to proj_angular_input() and proj_angular_output() but
checking for degree units instead. proj_create_crs_to_crs() rarely, if
ever, returns pipelines that has radians as input or output so using
proj_angular_*() is not a useful check for io units of pipelines.
These two new functions should make life a bit easier for users that
generally store there angular coordinates in radians.
Closes #2027

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.

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.

from their components
Support following syntaxes:
- OGC URN combining references for compoundCRS:
e.g. "urn:ogc:def:crs,crs:EPSG::2393,crs:EPSG::5717"
- its GDAL shortcut: e.g. "EPSG:2393+5717"
- OGC URN combining references for concatenated operations:
e.g. "urn:ogc:def:coordinateOperation,coordinateOperation:EPSG::3895,coordinateOperation:EPSG::1618"
