Re: [libvirt] [PATCH] Fix URL-escaping for domainDefine

'+' in strings get translated to ' ' when editing domains. While xenDaemonDomainCreateXML() did URL-escape the sexpr, xenDaemonDomainDefineXML() did not. Remove the explicit urlencode() in xenDaemonDomainCreateXML() and add the direct encoding calls to xend_op_ext() because it calls xend_post() which uses "Content-Type: application/x-www-form-urlencoded". According to <http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4.1> this requires all parameters to be url-encoded as specified in rfc1738. Notice: virBufferAsprintf(..., "%s=%s", ...) is again replaced by three calls to virBufferURIEncodeString() and virBufferAddChar() because '=' is a "reserved" character, which would get escaped by virBufferURIEncodeString(), which - by the way - escapes anything not c_isalnum().
