resolv: dead code removal
- hostalias() and res_hostalias(): these were no-ops
- res_opt(), res_querydomain(), p_option(), p_query(),
res_isourserver(), res_nisourserver(): had no callers
- res_ourserver_p(): made local to res_data.cpp
- res_send_setqhook(): unused, DnsProxyListener sets the qhook directly
in android_net_context, which is then copied to res_state by
res_setnetcontext(). We can further simplify it later on.
Test: atest netd_integration_test
