Annotate non-common kernel config options.

Annotate any kernel config option not present in all the kernel branches
regularly being tested (3.10, 3.18, 4.4, 4.9, 4.14) with when the option
was added or removed, and whether it was an Android kernel option or
not.

These annotations are useful when cross-checking the net tests list with
the kernel/configs project.
