proposal: add ULocale API to set and delete keyword values

This proposal is Java only.  Please respond by August 4.

Following the existing ULocale API, there are equivalent APIs to work on both a
ULocale object and on a locale ID string.  To change the keyword, pass the
keyword with a new value.  To delete the keyword, pass null as the new value. 
To delete all keywords, pass null as the keyword.

    /**
     * Sets the value for a keyword in this locale. If the value is null,
removes the keyword.  If the keyword is null, removes all keywords.
     * The new ULocale is returned.
     * @param keywordName name of the keyword whose value will be changed. 
Case insensitive.
     * @param keywordValue name of the value to assign to the keyword, or null
to remove the keyword
     * @return the resulting ULocale
     * @draft ICU 3.2
     * @deprecated This is a draft API and might change in a future release of
ICU.
     */
    public ULocale setKeywordValue(String keywordName, String keywordValue){
        return new ULocale(setKeywordValue(localeID, keywordName,
keywordValue), null);
    }
    
    /**
     * Set the value for a keyword in the specified locale. If the value is
null, removes the keyword.  If the keyword is null, removes all keywords.
     * The new locale ID is returned.  The locale name does not need to be
normalized.
     * @param keywordName name of the keyword whose value will be changed. 
Case insensitive.
     * @param keywordValue name of the value to assign to the keyword, or null
to remove the keyword
     * @return String the resulting locale ID
     * @draft ICU 3.0
     * @deprecated This is a draft API and might change in a future release of
ICU.
     */
    public static String setKeywordValue(String localeID, String keywordName,
String keywordValue) {
        return new IDParser(localeID).setKeywordValue(keywordName,
keywordValue).toString();
    }
