- change the buffer size from a constant to a

  TUNABLE variable (hw.netmap.buf_size) so we can experiment
  with values different from 2048 which may give better cache performance.

- rearrange the memory allocation code so it will be easier
  to replace it with a different implementation. The current code
  relies on a single large contiguous chunk of memory obtained through
  contigmalloc.
  The new implementation (not committed yet) uses multiple
  smaller chunks which are easier to fit in a fragmented address
  space.
