Dmitry V. Levin 5e023d62c1 scripts/functions: Minor code cleanup
Fatal, Verbose, Debug: Use Info().
ValidateBuildRoot: Use single quotes for constant string.
SetupMethods: Do not initialize loop variable. Use "tr -s".
RunMethods: Do not initialize loop variable. Use "echo ''" trick. Cleanup "$@" use.
ArgvFileAction: Do not initialize auto variable.
