remove android_open_proxy and use dns_open_proxy instead of it.
dns_open_proxy is in libnetd_client and
it does the same thing as android_open_proxy except return value.
It returns fd directly now.
Test: build, dns works fine

If libnetd_client can't be found, operate as before and use the default netId
potentially overriden by a more specific netId passed in to
android_get*fornet().

+ Name the dispatch header correctly (NetdClientDispatch.h).
+ Hide the global dispatch variable (__netdClientDispatch).
+ Explain why it's okay to read the variable without locking.
+ Use quotes instead of angle-brackets for non-system includes.
+ Add necessary declarations for C compiles (and not just C++).

Make sure __netdClientDispatch is defined in the same set of libraries that
refer to it (e.g.: with connect.cpp).
