* nvs_entry_find(), nvs_entry_next() and nvs_entry_info()
return error codes now
* nvs_entry_find() and nvs_entry_next() access/modify iterator via
parameters, instead of returning an new iterator.
Added appropriate documentation in Chinese and English
Console example doesn't duplicate code in `console` component.
Linenoise has been improved: it now has a parametrized command line
length. It is now possible to paste data efficiently to the console.
Note: this can only be done if the cursor is at the end of the line.
