Rework swsusp_shrink_memory() so that it calls shrink_all_memory()
just once to make some room for the image and then allocates memory
to apply more pressure to the memory management subsystem, if
necessary.

Unfortunately, we don't seem to be able to drop shrink_all_memory()
entirely just yet, because that would lead to huge performance
regressions in some test cases.

Fixed up trivial conflicts:

 - arch/x86/include/asm/socket.h

   converted to <asm-generic/socket.h> in the x86 tree.  The generic
   header has the same new #define's, so that works out fine.

 - drivers/net/tun.c

   fix conflict between 89f56d1e ("tun: reuse struct sock fields") that
   switched over to using 'tun->socket.sk' instead of the redundantly
   available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks
   to the TUN driver") which added a new 'tun->sk' use.
