Free always used 1024 based units but used the confusing old style
kilo,mega etc.
This change changes the names to kibi,mebi for 1024 based divisors
and kilo,mega for 1000 based divisors or IEC units.
It also checks if you try to set two units, e.g free -k -m
Petabyte and Pebibyte have been added.
If you used to use the long options such as --mega these will now
actually print megabytes (they previously printed mebibytes).
The short options are being used on the IEC units

procps works well on Linux, on other arches there are some strange
differences due to their emulation of procfs which is not 100%
Disabling checks for non-linux until that can be sorted out.
