Btrfs bug fixes and improvements for 4.11 (2nd retry)

From: Filipe Manana <[email protected]>

Hi Chris, since my previous pull request (sent timely) was either missed or not pulled for some reason I'm not aware of, here I send it again (with one more patch included). The following is taken from the former pull request:

"Please consider the following changes for the 4.11 merge window. This time there is nothing particularly outstanding when compared to the usual set of bug fixes. These are mostly fixes for send and the no-holes feature introduced in 3.14. Test cases for fstests were sent for half of these changes, with some already merged and two not yet merged."

This was rebased against your current for-linus-4.11 branch and re-tested.

Thanks.

The following changes since commit 6288d6eabc7505f42dda34a2c2962f91914be3a4:
