This patchset introduces the include-what-you-use script which removes
unused header includes. IWYU GitHub:

https://github.com/include-what-you-use/include-what-you-use

Along with the script there are some patches which make a start on
removing unneeded headers.

V4:
* Re-added removed headers that are now needed in order to fix build
  issues.
* Removed other unused headers from other libraries
