Make sure all cached buffers with valid, not yet written data have been
run through copy-on-write.  Call fscow_run() with valid data where possible.

The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against
endless recursion.

- Add a flag B_MODIFY to bread(), breada() and breadn().  If set the caller
  intends to modify the buffer returned.

- Always run copy-on-write on buffers returned from ffs_balloc().

- Add new function ffs_getblk() that gets a buffer, assigns a new blkno,
  may clear the buffer and runs copy-on-write.  Process possible errors
  from getblk() or fscow_run().  Part of PR kern/38664.

Additional fixes/enhancements:
    1) Comply with the way buffercache(9) is intended to be used. Now we
       read in single blocks of EFS_BB_SIZE, never taking in variable
       length extents with a single bread() call.

    2) Handle symlinks with more than one extent. There's no reason for
       this to ever happen, but it's handled now.

    3) Finally, add a hint to our iteration initialiser so we can start
       from the desired offset, rather than naively looping through from
       the beginning each time. Since we can binary search the correct
       location quickly, this improves large sequential reads by about
       40% with 128MB files. Improvement should increase with file size.
