a31ddef36d Change how DNS resolver handle no default iface
We used to just try any iface we'd been told about as a
fallback, but that will end up mistakenly using a secondary
network's dns when we really don't have a default connection.

It also messed up our detection of whether we were doing the
lookup on the default or not (we'd get back our secondary net
iface as the default, do the compare and think we were on default).

Remove the lies and let dns fail if we don't have an iface for it.

5cf32de7a0 bionic: move system property writing from init to bionic
Move the implementation of writing to the system property area
from init to bionic, next to the reader implementation.  This
will allow full property testing to be added to bionic tests.

Add new accessor and waiting functions to hide the implementation
from watchprops and various bionic users.

Also hide some of the implementation details of the property area
from init by moving them into _system_properties.h, and other details
from everybody by moving them into system_properties.h.

(cherry picked from commit dc1038b790)

Also use O_CLOEXEC when opening the /dev/log files.

Move everything logging-related into one header file.

ce5ba8bfcd Added missing cache failed notification
Added a missing call to _resolv_cache_query_failed for another fail
case where it was missing (it doesn't go through the error handling
under the "fail" label). This missing notification caused requests to
have to wait for timeout instead of beeing notified on some failed
requests.

a59cfcfd08 Avoid multiple dns lookups for the same query
If two or more rapid dns requests for the same server are done
from different threads it turns into separate dns reques, if
the response of the request isn't found in the cache.

This patch avoid multiple request for the same server by
letting subsequents request wait until the first request
has finished.
