Move the common declarations and initializations from ci_verify_*.sh
to ci.lib.sh, and update them as follows:
* Simplify the ci_ function names.
* Refactor the CI_ variable names:
- Add the new variable CI_TOPLEVEL_DIR.
- Rename the variables CI_SCRIPTNAME, CI_SCRIPTDIR, etc.,
to CI_SCRIPT_NAME, CI_SCRIPT_DIR, etc.
- Rename the variables CI_SRCDIR_FROM_BUILDDIR, etc., to
CI_BUILD_TO_SRC_RELDIR, etc.
* Add new functions inside ci.lib.sh:
- Replace ci_err with ci_err_usage, ci_err_fatal, ci_err_internal.
- Add the new functions ci_warn and ci_assert.
* Simplify the ci_ function names inside ci_verify_*.sh.
