Always update search domain paths.
_resolv_set_nameservers_for_net() so far did not update the search
paths, unless the servers changed as well.

DO NOT MERGE Add new info functions to resolver for use by Netd.
android_net_res_stats_get_info_for_net returns the current name servers, search
domains, parameters and stats for the given network ID.
android_net_res_stats_aggregate provides statistics such as errors counts from
the raw stats data reported by android_net_res_stats_get_info_for_net.
android_net_res_stats_get_usable_servers uses the data returned by
android_net_res_stats_aggregate to determine which of the servers are
considered valid or broken by the resolver.

DO NOT MERGE Store DNS server count in resolv_cache.
Instead of keeping a sentinel after nameservers[], nsaddrinfo[] and
nstats[], store the server count in the structure, freeing up memory and
eliminating the need to enumerate the server count every time
_resolv_is_nameservers_equal_locked() is invoked.
Also increase MAXNS from 3 to 4.

Copy the entire zero-separated DNS seach domain string.
The DNS search string contains zeros as domain separator. The resolver
code erroneously used strlcpy(), which resulted in only the first domain
to be copied. The code uses pointers into this string to access the
individual domains. Since the structure is zero-initialized, this bug only
resulted in zero-length domains instead of accessing unitialized memory.

Fix all resolv warnings and turn on -Werror.
The res_init.c changes bring us a bit closer to upstream too, though
there's still work to be done there. Some of the remaining differences
look like bugs we'd want to fix, so we should definitely try to come
back to that.

Add support for deleting per-network DNS resolver caches.
This is required when the possible range of NetIds is large to
prevent netd consuming excessive amounts of memory.
This required replacing the per-cache locks in favor of a single
global lock to prevent accesses to deleted caches.

bionic: Replace iface with opaque netid in resolver.
Replace iface cache key with netid.
Replace _mark with netid.
Mark sockets used to test IPv4/IPv6 support as well as sockets
used to determine source address for rfc6724 sort.
Remove pid/uid mappings (functionality moved to system/netd).
Do not create resolv_cache when it does not exist, but rather only
when DNS configuration is supplied.
Clean up unused functions.
