* Add space between values in docker stats output for easier parsing
Old output could not be parsed easily because there were columns
that did not have any separator. Also values that are together
without any space is difficult to read even for humans.
* Update unit.HumanSize comment to match what the does actually does

Both functions perform the same logic and they just vary on the base
multiplication units. We can refactor the common code into a single
place.

No need to initialize every time the function executes since it works as
a catalog.

No need to have two lines. The type is even explicit when type casting
to `float64(size)`

No need to recompile a fixed regular expression each time the function
executes. Abstracting it to the `init()` method.

May make sense that both `FromHumanSize()` and `RAMInBytes()` support
the same units. Added 'PB' to the RAMInBytes regex.
Also updated tests.
Note: int64 is overflowed on quantities >= EB

Better to not use `error` as var name (might eclipse the error type) for
clarity and to prevent subtle bugs.

Remove named returns since not used in function body. Might prevent
potential subtle bugs.

Device Mapper needs device sizes in binary (1024) multiples. Otherwise
kernel checks can find that the specified thin-pool device sizes aren't
a multiple of the specified thin-pool blocksize.
The name for "RAMInBytes" is likely too narrow given the new consumers
but... Also add "tebibyte" support to RAMInBytes.

This does the "reverse" of HumanSize, i.e. maps a string to an int64
using SI prefixes for the extension.
