From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Using the include-what-you-use tool as a guide
a) Drop unnused headers.
b) Add missing headers for functionality directly used in this file.

Note that this is not an automated process and in somecases the
suggestions were ignored, or a different header included to reflect
what I understand to be expected structure of includes.
