DNS Proxy should not hang on addresses containing null bytes
Two bugs here:
1.) The gethostbyaddr netd protocol was passing a binary address value
but the arguments are expected to be strings not containing
embedded nulls (or probably other special characters). This
happened reliably with IPv6 addresses which contained nulls. It
now expects an inet_ntop formatted address.
2.) Although the gethostbyaddr code detected something was wrong, it
wasn't doing any proper error handling, leaving clients hanging
waiting for a response. It now sends back an empty response so
that clients can continue.
A corresponding change will be necesssary in bionic for #1 for DNS
proxying to work, but given the fix for #2, the existing bionic code
will fall back to performing its own gethostbyaddr call.

Reference count SocketClients.
Avoids a netd crash when the client closes its connection while
a DNS request is in-flight.
Depends on Icd7f5f03 in system/core.

Add GetHostByAddrHandler to DnsProxyListener
Added functionality to handle gethostbyaddr
in DnsProxyListener. The functionality is
used by getnameinfo. The patch is part of the
work to have one dns cache for all process in
the system.

Fix DNS proxy.
Don't assume writing 0 bytes to SocketClient will be successful. (as
implemented in libsysutils right now, it returns an error...)

DNS proxy thread in netd.
New thread in the netd process which listens on the
/dev/socket/dnsproxyd socket (group owned by 'inet', so only useable
by apps with the INTERNET permission), and does getaddrinfo requests
for other processes, caching in one place, rather than per-app.
Still remaining: proper caching based on DNS-requested lengths, upping
the cache size, getnameinfo, stats, flush, etc, etc.
