Add the new functions _run_env(), _exit_env(), _init_env() and
_cleanup_env() to run the tests inside a new environment specified with the
TST_ENV environment variable.
A typical structure of a script with tests is:
trap '_report_exit_and_cleanup _cleanup_env cleanup' \
SIGINT SIGTERM SIGSEGV EXIT
cleanup() {
<test cleanup>
}
<tests implementations>
_run_env "$TST_KERNEL" "$PWD/$(basename "$0")" "env_var1=$env_var1 ..."
_exit_env "$TST_KERNEL"
_init_env
<tests init>
<tests call>
If TST_ENV is not set or empty, don't create a new testing environment and
perform the cleanup in the current environment. Don't create a new testing
environment also if the script is already executed in a new environment, to
avoid loops. Instead, for cleanup, do it in the new environment and skip it
in the host environment (if the cleanup function is passed to
_cleanup_env()).
Signal to the creator of the environment failures of tests or of the script
itself run in the new environment (if the exit code is 1 ($FAIL) or 99
($HARDFAIL)) with an unclean shutdown of the system.
Add haveged and systemd as dependencies for the tests in ci/fedora.sh,
respectively for initializing the random number generator and for shutting
down the system in the new environment.
