v0.33.0, breaking release

[Croydon]

Breaking Changes / Removed features

• Increasing conan_package_tools min version to >=0.39.0 as 0.39.0 added support for CONAN_GLOBAL_CONF
• Remove Clang 3.9 builds from the default build matrix
• Visual Studio 2017 was dropped since GitHub Actions and Azure Pipelines are dropping support for it (see Windows-2016 environment will be removed on March 15, 2022 actions/runner-images#4312)
• Remove build_template_boost_default.py, build_template_boost_header_only.py, build_template_default.py, build_template_header_only.py or build_template_installer.py files. build.py files that make use of those files will break. Migrate to use the auto-detect feature (or if you can't use the auto-detect feature for some reason, a custom build.py file that does not try to import these files).

Deprecated Features / Will be removed in a future release

• Support for AppVeyor CI is deprecated. AppVeyor does not allow dynamic matrix generations which we need for most modern features.
• Clang < 10 builds will be removed from the default build matrix
• GCC 4.9 builds will be removed from the default build matrix
• Apple Clang 10 builds will be removed from the default build matrix

Upcoming Features Early Notice

• Bincrafters Package Tools will start to use semantic versioning
• The usage of the "modern" Conan Docker Tools containers will be extended to Clang >= 10 builds (see https://github.com/conan-io/conan-docker-tools/tree/b693dc3507cf16e7ec5db50e002765420b747651/modern); this might cause incompatibilities with existing builds and setups
• Clang 13 builds will be added to the default build matrix
• Use the Conan 2.x behaviour to always use 2 profiles (host and build) - This might break old recipes

New Features

• Add GCC 11 and Clang 12 builds to the default build matrix
• Use "modern" Conan Docker Tools containers for GCC >= 11 and Clang >= 12 build jobs (see https://github.com/conan-io/conan-docker-tools/tree/b693dc3507cf16e7ec5db50e002765420b747651/modern)
• Add environment variable BPT_MATRIX_DISCARD_DUPLICATE_BUILD_IDS. Options: true/false, default: true. This does NOT YET what it says. Right now, this only has an effect for installer_only and header_only recipes when set to false. In those cases, you get the full build matrix, instead of a shortened build matrix. In the future, the matrix generation actually compares build IDs and discards jobs based on the IDs. ([BPT] Header only libs have limited job matrix. community#1391)

Other Improvements

• Change the default remote URL to Bincrafters' Artifactory remote (it was still pointing to Bintray)
• Some more adjustment to support the msvc compiler model (though, it still does not work completely)
• Add Apple Clang -> XCode mappings for newer versions

Bugfixes

• Enable installing system packages also for Conan 2.x system package tools
• Do not set CONAN_DOCKER_ENTRY_SCRIPT, but append instead

Internal Improvements

• Allow getting the builder for autodetect builds without executing the builder
• Add Dependabot to repository

TODO

• Figure out why changing the default remote URL is changing either the Conan remote name or the order of the remotes (what the hell)
• Don't fail when GHA or AZP don't get any build jobs on purpose (requires changes in templates and tooling; breaking change; e.g. for installers when AZP shouldn't run at all or changes that don't affect any Conan recipe in a repository)
• Installer build job names have double Release in their names: https://github.com/bincrafters/community/runs/3781824922?check_suite_focus=true
• Fix or remove VS 2022 preview builds environment
• VS 2022 Testing builds will be migrated to the new Conan MSVC compiler model, once upstream support is done (see Add MSVC compiler support throughout CPT conan-io/conan-package-tools#580)
