Subject: [PATCH] Add capability to get and set the personalitty function from
 the C API

Summary:
The capability was lost with D10429 where the personality function was set at function level rather than landing pad level. Now there is no way to get/set the personality function from the C API. That is a problem.

Note that the whole thing could be avoided by improving the C API testing, as started by D10725
