libsysutils: Add iovec/runOnEachSocket

SocketClient:
* Replace sendDataLocked with sendDataLockedv which takes an iovec.
* Add a version of sendData, sendDatav, which takes an iovec.
* do not preserve iovec content through sendDatav

SocketListener:
* Add runOnEachSocket, which allows to to specify a SocketClientCommand to
  run individually on each socket. This allows you to do broadcast-like
  actions customized for each individual socket.
* Client safe list reference counting for sendBroadcast & runOnEach Socket

ueventd: fix a busy loop while reading uevents

Under certain conditions, poll() may raise the POLLERR
flag along with POLLIN, in which case the check for

Apply strict SELinux checking of PROT_EXEC on mmap/mprotect calls.

If checkreqprot == 1, SELinux only checks the protection flags passed
by the application, even if the kernel internally adds PROT_EXEC for
READ_IMPLIES_EXEC personality flags.  Switch to checkreqprot == 0
to check the final protection flags applied by the kernel.

Set security context of /adb_keys and /data/misc/adb/adb_keys.

I97b3d86a69681330bba549491a2fb39df6cf20ef introduced a separate type
for the adb_keys file.  Set the security context of the adb_keys file
accordingly by adding restorecon commands to init.rc.

Move restorecon and restorecon_recursive code to libselinux.

This requires telling libselinux to use the sehandle already
obtained by init rather than re-acquiring it internally.  init
retains ownership of the sehandle because it performs the
initial load, uses the sehandle for other purposes (e.g. labeling
of directories created via mkdir and labeling of socket files),
and handles the policy reload property trigger.
