Add pre-commit hooks for trailing whitespaces and newline at file end
Add pre-commit hook for tmt linting
Add pre-commit hook for static analysis on shell scripts (shellcheck)
Fixed issues flagged by shellcheck.
Move to dedicated directory. Removed no longer needed package
adjustments which are now provided by the tests. Also included
the integration testsuite to the plan and added the needed
prepare steps for it
This test used /usr/bin/true to check that lldb doesn't crash with
DW_FORM values 0x1f20 and 0x1f21, but this is not happening in all
distros. Also there's no way to guarantee that it will stay this
way in future distros as well. Replaced with a a reproducible test
that generates debug info with the required DW_FORM values
