* Remove unused jenkins stuff
* Install all dependencies in builder image
Instead of only target specific dependencies.
* Use docker builder image for builds
* Optimize apt installations
* Move building of dependencies into separate stage
The build-depends-xxx jobs will create artifacts (depends/$HOST) which are
then pulled in by the build jobs with the help of "needs"
* Remove use of caches from develop branch
* Use gitlab specific extends instead of YAML anchors
* Move before_script of build_template into base_template
* Add hack for parallel installation of i686 and arm cross compilation
* Install python3-setuptools in builder image
* Remove unnecessary change-dir
* Use variables to pass BUILD_TARGET instead of relying on the job name
* Move integration tests into separate stage
* Don't use --quiet for integration tests on Gitlab
* Make parent cache download quiet
This spammed logs quite a bit
* Add "-p" to "mkdir $CI_PROJECT_DIR/cache-artifact"
Otherwise the after_script is silently aborted when the dir already exists.
* Extract parent cache artifact in own directory and later delete it
Otherwise we end up having "testlogs" (and maybe other stuff) in the
project directory, which causes future failures.
* Add .gitlab-ci.yml
* Use | instead of > for multiline commands
This honor new-lines and makes ; unnecessary
* Use ubuntu:bionic as base image
* Move cache initialization before apt-get installs
* Cache apt packages
* Move installation of wget and unzip up as we need it for the cache
* Prevent apt from deleting caches
* Collect test logs into artifact
* Make combine_logs.py always look for the template in the correct dir
* Move final cache stuff into after_script
* Reintroduce PYTHON_DEBUG=1, but only for .travis.yml
* Install jinja2 in Travis builder image
* Enable ChainLocks after quorums have been created
Creating 4 quorums causes a lot of blocks to be created and signed by
ChainLocks, which then causes timeouts later.
* Increase timeout in wallet-dump.py test
The first dumpwallet is quite slow sometimes, which then makes the
later called dumpwallet throw a wallet locked exception.
