pollableStreamRead

Tries to read from stream, as with InputStream.read (if blocking is TRUE) or g_pollable_input_stream_read_nonblocking() (if blocking is FALSE). This can be used to more easily share code between blocking and non-blocking implementations of a method.

If blocking is FALSE, then stream must be a GPollableInputStream for which g_pollable_input_stream_can_poll() returns TRUE, or else the behavior is undefined. If blocking is TRUE, then stream does not need to be a GPollableInputStream
