Unicode script support in Regex and Character class

[Xueming Shen]

Hi,

Here is the webrev of the proposal to add Unicode script support in 
regex and j.l.Character.

http://cr.openjdk.java.net/~sherman/script/webrev

and the corresponding blenderrev

http://cr.openjdk.java.net/~sherman/script/blenderrev.html

Please comment on the APIs before I submit the CCC, especially

(1) to use enum for the j.l.Character.UnicodeScript (compared to the 
traditional j.l.c.Subset)
(2) the piggyback method j.l.c.getName() :-)
(3) the syntax for script constructs. In addition to the "normal"
     \p{InScriptName} and \P{InScriptName} for the script support
     I'm also adding
    \p{script=ScriptName} \P{script=ScriptName}  for the new script support
    \p{block=BlockName} \P{block=BlockName}  for the "existing" block 
support
    \p{general_category=CategoryName} \P{general_category=CategoryName} 
for the "existing" gc
    Perl recently also started to accept this  \p{propName=propValue} 
Unicode style.
    It opens the door for future "expanding", for example \p{name=XYZ} :-)
(4)and of course, the wording.

Thanks,
Sherman
