android_get_control_socket has a warning from the implicit cast from
long to int. The warning was being hidden because cutils/sockets.h was
included with -isystem. Move android_get_control_socket to sockets.cpp,
since we don't want header only dependencies anyways, and fix the
warning with a range check and a static_cast.

Test: m -j <module that uses sockets.h and -Wall>

While lmkd does technically use libcutils' socket.h, it only
uses a static inline. Remove libcutils from LOCAL_SHARED_LIBRARIES
so it doesn't end up mlock'd in memory in the next patch.

Statically linked binaries cannot take advantage of ASLR,
making them less secure.
In addition, statically linked binaries consume more ram,
because shared libraries cannot be reused.

Move kernel low memory killer logic to new daemon lmkd. ActivityManager
communicates with this daemon over a named socket.
