    manual: Fix examples to check for gst_buffer_map return values

    Otherwise people reading the manual will expect it to always
    succeed :)

    plugins: Check return values of gst_buffer_map()

    They can fail for various reasons.

    For non-fatal cases (such as the dump feature of identiy and fakesink),
    we just silently skip it.

    For other cases post an error message.

    Only do memory operations if the memory was succesfully map'ed
