Bug description:  mb_strwidth() width table is wrong

Description:
------------
The table describing the width of the characters is wrong if you compare
it with the table for Unicode 4.0:

http://www.unicode.org/Public/UNIDATA/EastAsianWidth.txt

For the BMP the wide/full-width chars are:

1100..115F  Hangul Choseong
2E80..4DB5  CJK radicals and CJK Ideograph Extension A
4E00..D7A3  CJK Ideographs, Yi syll. and Hangul syll.
F900..FA6A  CJK compatibiliy ideographs
FE30..FE6B  presentation forms, punctuations, etc.
FF01..FF60  full-width Latin letters
FFE0        FULLWIDTH CENT SIGN
FFE1        FULLWIDTH POUND SIGN
FFE2        FULLWIDTH NOT SIGN
FFE3        FULLWIDTH MACRON
FFE4        FULLWIDTH BROKEN BAR
FFE5        FULLWIDTH YEN SIGN
FFE6        FULLWIDTH WON SIGN

I didn't check what the actual implementation does, but the docs are
certainly wrong (if they mean Unicoe codepoints).
