Rename the WAP protocols so that they reflect the protocol name and not the protocol stack name. Fix the WSP content-type header. Rename the WSP header fields from 'hdr' to 'header'. Rename the WSP Openwave header fields from header code page 'x-up-1': replace 'openwave' with 'x_up_1' (is more intuitive). Remove unused WSP header fields. Rename the WTLS header fields so they do not contain 'wsp' anymore. Correct the WBXML code page switches in the token parsers. Fix the code page support of multi-codepage content. Update the PROV WBXML content (and find bugs in the new OMA Prov spec :). svn path=/trunk/; revision=9291
