Database: tune accuracy of Canadian NTv1 file w.r.t NTv2

2019-12-25T15:23:31+00:00

As on import of EPSG, we remove the supersession of Canadian NTv1 file w.r.t NTv2
(because the default behaviour of PROJ is to ignore superseded operations). However
the NTv1 operation is advertized with an accuracy of 1m, whereas NTv2 is advertized
with 1.5m. Consequently on areas where both files are valid, and if both files are
available, NTv1 would be selected. So as a workaround, worsen the NTv1 accuracy to
2m so that NTv2 is used in priority.

Upgrade testing from trusty to xenial, and also:

2019-09-25T08:50:07+00:00

* From openjdk-7 via apt to openjdk-11 via Travis CI xenial's $JAVA_HOME
* From mingw 4.8 -> 5.3, as supported by xenial
* clang+llvm for csa kept at version 6.0.0, but for ubuntu-16.04
* Furthermore xenial implicitly has many upgrades, specifically:
  - gcc 4.8.4 -> 5.4.0
  - clang 4.0.0 -> 5.0.0
  - cmake 3.9.2 -> 3.12.4
  - python 3.4.3 -> 3.5.2
* cppcheck version kept at 1.61 (for trusty) due to many
  false positives with version 1.72 (for xenial)
* Community code contribution documentation simplified to remove
  version of cppcheck, as this may outdated with updates to scripts

Rearrange Travis CI scripts to be more modular

2019-09-24T23:16:27+00:00

* Split global before_install for apt and pip
* Use -qq option for apt-get, which implies -y
* Use list of targets with apt-get rather than one-per-line
* Use local variables for mingw32/install.sh
* Show version info for cppcheck, pip and python
* Simplify clang+llvm-6 path
