volume_id: add LittleFS detection

2018-01-19T19:37:13+00:00

Add support for LittleFS to blkid. Not included if FEATURE_BLKID_TYPE is not selected (neither UUID nor label). LittleFS is a small fail-safe filesystem designed for embedded systems. It has strong copy-on-write guarantees and storage on disk is always kept in a valid state. It also provides a form of dynamic wear levelling for systems that can not fit a full flash translation layer. (https://github.com/geky/littlefs) ARM has introduced it in its Mbed OS 5.7, so it starts to gain focus.
