Couple of API improvements:

- SF_NOCACHE flag from userland says that when an mbuf is freed, the
  referenced page should go into free pool, instead of being cached
  with associated object.
  This is achieved via alternative ext_free function. While here also
  rename sf_buf_mext() to a more meaningful name.

- Bits above 16 in flags now count number of pages that sendfile(2)
  is allowed to readahead when processing the request.
