Prior to this patch, we had four separate header files
dealing with miscellaneous functions. Those four files
were documented in the single man page: procps_misc.3.
Now, we will have just a single header file documented
in a single man page (that is what's called symmetry).
[ and while we're at it, we will shorten that overly ]
[ long struct 'procps_namespaces' name to agree with ]
[ the function naming conventions, e.g. 'procps_ns'. ]
