RFR: 8234185: Cleanup usage of canonicalize function between libjava, hotspot and libinstrument

[Langer, Christoph]

Hi David,

I prepared an updated webrev: http://cr.openjdk.java.net/~clanger/webrevs/8234185.3/

Well, it's actually not needed but I think it's good practice that the declaring header is included in the implementation file.

Same as for the windows file - not necessary but good style.

I did as Dan pointed out.

Right, thanks for the catch.

Dan, can I add you as reviewer then?
