This provides memory management related data to the Linux - VM Monitor
Stream, like paging/swapping rate, memory utilisation, etc.
Writing 1 or 0 to /proc/appldata/memory creates(1) or removes(0) a z/VM
APPLDATA monitor record, i.e. enables or disables monitoring this record
on the z/VM side.

Default is disabled.
The /proc entry can also be read from, showing the current settings.

This can also be compiled as a module, which will be called
appldata_mem.o.
