90de53f970 rwrap: Fix ns_name_compress detection.
On some platforms it is a macro and not a function. So we need to
check if the macro exists.

931dbb3202 rwrap: If we do not have ns_name_compress() use dn_comp().
This should fix older Linux versions which do not export
ns_name_compress(). In newer glibc versions dn_comp() calls
ns_name_compress().

aa78268a49 rwrap: Make the rwrap_fake_* functions only fake RRs.
The rwrap_fake_common() function did too much. Remove it and use
separate functions to add fake header and question sections. The
rwrap_fake_$RR functions will receive packet including the header and
question and only add its RR data.

This will allow recursive processing later.

When querying for a SRV record, we'll need to include A or AAAA records
in additional section. Therefore, keep querying the host file until we
can either recurse the A/AAAA records or reach the recursion limit
