These aren't exactly the result of `missing public APIs'. echoing_p is
a saved value indicating whether or not the terminal flags readline
inherits include ECHO -- something an application can easily check for
itself.
The others are values for settable variables and should be retrieved
using rl_variable_value (variable_name). Since it returns a string,
you can use the public macro RL_BOOLEAN_VARIABLE_VALUE to turn it into
an int.
Bash doesn't use any _rl_ readline symbols, so I know it can be done.
