RFR: JDK-8153073: UL: Set filesize option with k/m/g

[Yasumasa Suenaga]

Hi all,

This request review is related to [1].

I want to set filesize option with k/m/g as below: 
           -Xlog:gc=trace:file=gc.log:time:filecount=5,filesize=10m 

Memory size option (e.g. -Xmx) can be set with k/m/g .
I think we can use option parser in arguments.cpp . 

I uploaded webrev. Could you review it?

I cannot access JPRT. So I need a sponsor.


Thanks,

Yasumasa
