Add several more subroutines for test logging.

	- log_debug: Only print the string if $STF_DEBUG is set.
	- log_mustbe: Like log_must, but the first argument specifies the
	  required exit code; since its behavior differs from log_must in
	  certain ways that assume a success exit code of zero, it is not used
	  by log_must.
	- log_cmd: Log the given command and its exit code, but let the caller
	  decide how to deal with the returned exit code.
	- log_onfail: Like log_cmd, but only logs on failure.
