        lib/libc/resolv/res_init.c:     revisions 1.11, 1.12 via patch
Don't check for ext being NULL to destroy the res_state. Instead check
the option bits like we did before.
Only try free-ing a version of res if it is not supposed to be pre-inited
like before. Fixes issues with programs passing random uninitialized data
as res_state.
