Commit Message

Blank DNS names would result in ARES_ENOMEM due to bug in query cache

If a blank DNS name is used, the DNS query cache would fail due to an
invalid sanity check.  This can be legitimate such as:

adig -t SOA .

This fixes that situation as well as a few other spots that were
uncovered and adds a test case to validate the behavior to ensure
it won't regress in the future.

Fixes #858
