lwip: Split sources into origin directories

Moving forward, each origin directory should have its own top-level
COPYING.origin file to describe its license as well as a ORIGIN.origin
file to describe where the code is sourced from.

- * Everything seems to be just fine however during RX, after we call

- * properly set the apropriate BDs. This will however work only if the
- * number of the freed BDs is the same as the number of the BDs newly
- * initialized. One possible situation when this may fail is when multiple
- * non-256 byte sized PBUFs will move near to each other, i.e. 3 BDs:
- * 256 B, 44 B, 44 B -- 344 bytes will be freed (3 BDs) but the new call
- * to pbuf_alloc(...) will return a chain comprising only two PBUFs
