memsw: deprecate noswapaccount kernel parameter and schedule it for removal
noswapaccount couldn't be used to control memsw for both on/off cases so
we have added swapaccount[=0|1] parameter. This way we can turn the
feature in two ways noswapaccount resp. swapaccount=0. We have kept the
original noswapaccount but I think we should remove it after some time as
it just makes more command line parameters without any advantages and also
the code to handle parameters is uglier if we want both parameters.
