Doc: fixes for Sphinx 3.0 compat [skip appveyor] (#2191)

2020-04-24T16:42:05+00:00

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.

.travis.yml: switch to bionic to restore i386 builds with gcc8 (fixes #2175)

Credits to @sebastic for his suggestion to try bionic and use aptitude
instead of apt !

Add post-install checks for CMake and Autotools/pkg-config (#2077)

2020-03-21T01:16:00+00:00

* Checks CMake's find_package(PROJ) and find_package(PROJ4)
* Checks pkg-config used with a Makefile (Linux and macOS only)
* Use proj.h / libproj with a simple 'testappprojinfo'

Update docs in preparation for 7.0.0 release

Make tests independent of proj-datumgrid

2020-02-27T12:19:13+00:00

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
