Constify add_info

This patch constifies add_info and updates all the info commands.  The
bulk of this patch was written using a script; and then I did a manual
pass to fix up the remaining compilation errors.

I could not compile every changed file; in particular nto-procfs.c,
gnu-nat.c, and darwin-nat-info.c; but I at least tried to check the
correctness by inspection.
