Adding FIXMEs without an intent to actually fix them would be stupid.

The FIXMEs direct "make check-headers" to skip the headers so marked.
Without the FIXMEs, "make check-headers" fails.  I want it to succeed,
so we can run it from "make check", and gain protection against clean
headers becoming unclean.

What "make check-headers" covers is for us to choose.  This RFC series
starts with include/, then widens to everything in two big steps:

* PATCH 5: include/.  764 headers, 179 known-bad.

* PATCH 6: all of the source tree.  Adds 797 headers, 409 known-bad.

* PATCH 7: plus generated headers.  Adds 177 headers, 3 known-bad.

We can start smaller, and take smaller steps.
