RFR:JDK-8155823: Add date-time patterns 'v' and 'vvvv'

[Roger Riggs]

Hi Nadeesh,

java/time/format/DateTimeFormatter.java: line 312

  - Move 'v' up 1 line so it is after 'V' and before 'z'.
    Also in DateTimeFormatterBuilder.java: line 1415+

  - the description of the number of letters does not need to be repeated;
    put one copy before the  specifics of 'z' and 'v'.

"If the count of letters is one, then the short name is output.
+ * If the count of letters is four, then the full name is output.
+ * Two, three and five or more letters throw {@code 
IllegalArgumentException}."

DateTimeFormatterBuilder.java
  - line 1625/1626: should include what happens with vv and vvv to be 
consistent with DateTimeFormatter doc for ZoneId names.

  - line 1647: The description in DateTimeFormatter says that count = 2 
and 3 should also produce the short value
    but the code will throw IAE.

  -line 1988: "almost"  ---  can this be more specific about what 
matches or does not match

In the test it is a bit bothersome that the tests have to rely on 
timezone specific data.

Thanks, Roger
