mem: adds information about used memory without freeable parts

* used memory (values 1 and 2) are: everything but free+cache
* laundry is counted as freeable, but not free.
** "notfreeable memory" (values 11 and 12) are: active+inactive+wired

total system memory, 4th as free memory, 5th as swap usage in percent, 6th
as swap usage, 7th as total system swap, 8th as free swap and 9th as
memory usage with buffers and cache
* FreeBSD: see above, but there are two more values: the 9th value is wired memory
in percent and the 10th value giving wired memory
* FreeBSD: see above, but there are four more values: the 9th value is wired memory
in percent, the 10th value is wired memory. The 11th and 12th value return
'not freeable memory' (basically active+inactive+wired) in percent and megabytes,
respectively.
