- incorporate local cache cleaner

- enable global byte-range locks

- enable global fsync coordination (open delayed until any client finished his fsync)

- add max file-size support returning EFBIG

- adding rudimentary quota honoring on client side

Progressing as planned.

Server-side is assumed to be ready on Monday (Luca would like pre-/post tags ..)

CDo we set up some "experimental" area on some instance (on EOSUAT?)

"eosfusebind": need to keep compat, even if no longer needed.
