Willy Tarreau 0a0041d195 BUILD: tree-wide: fix a few missing includes in a few files
Some include files, mostly types definitions, are missing a few includes
to define the types they're using, causing include ordering dependencies
between files, which are most often not seen due to the alphabetical
order of includes. Let's just fix them.

These were spotted by building pre-compiled headers for all these files
to .h.gch.
