Hello,

I have made an attempt at fleshing out the resolver tests, please see the file attached. It still needs some polishing, and I am keen to keep building out the necessary tests, attached is a simple rudimentary res_query() test. I need to improve the packet and RR parsing, but sending this out to get some early feedback before I build out more tests.

I have just been building the test and the unshare-ns.c framework with the libc-test build system, executing unshare-ns.exe and passing in resolv_query.exe as intended.

Thanks,
rw
