Run the given command in a shell and return the shell return code and the

cmd_buf The command string to be run in a shell.
quiet Indicates whether this function should run
the print_issuing() function which prints
"Issuing: <cmd string>" to stdout.
test_mode If test_mode is set, this function will
not actually run the command. If
print_output is set, it will print
"(test_mode) Issuing: <cmd string>" to
stdout.
debug If debug is set, this function will print
extra debug info.
print_output If this is set, this function will print
the stdout/stderr generated by the shell
command.
show_err If show_err is set, this function will
print a standardized error report if the
shell command returns non-zero.
return_stderr If return_stderr is set, this function
will process the stdout and stderr streams
from the shell command separately. It
will also return stderr in addition to the
return code and the stdout.
