RFR: 8151876: (tz) Support tzdata2016b

[Masayoshi Okutsu]

Sorry for this belated response.

I prefer to follow the tzdata abbreviations, like "+04". But that would 
require some major changes. An option would be not to define time zone 
names for the new zones with the +hh format.

Thanks,
Masayoshi

(Also, it looks like the abbreviations similar to "+03/+04" will be used for the zones linked to the rule set with changing letters like: EST/EDT for US, MSK/MSD for RU, etc..).
