RFR [9] 8133651: replace some <tt> tags (obsolete in html5) in core-libs docs

[Alexander Stepanov]

Hello,

Could you please review the following fix
http://cr.openjdk.java.net/~avstepan/8133651/jdk.00/
http://cr.openjdk.java.net/~avstepan/8133651/jaxws.00/index.html
for
https://bugs.openjdk.java.net/browse/JDK-8133651

Just another portion of deprecated <tt> (and <xmp>) tags replaced with 
{@code }. Some misprints were also fixed.


The following (expected) changes were detected by specdiff:
- removed needless dashes in java.util.Locale,
- removed needless curly brace in xml.bind.annotation.XmlElementRef

Please let me know if the following changes are desirable or not:

Thanks,
