  @118494 Integrate changes from vendor.
  
  @118504 Fix sendfile(2). I had two ways of fixing it:
          1. Fixing sendfile(2) itself to use VOP_GETPAGES() instead of
             hacking around with vn_rdwr(UIO_NOCOPY), which was suggested
             by ups.
          2. Modify ZFS behaviour to handle this special case.
  
          Although 1 is more correct, I've choosen 2, because hack from 1
          have a side-effect of beeing faster - it reads ahead MAXBSIZE
          bytes instead of reading page by page. This is not easy to implement
          with VOP_GETPAGES(), at least not for me in this very moment.

  @118525 Reorganize the code to reduce diff.
  
  @118526 This code path is expected. It is simply when file is opened with
          O_FSYNC flag.
