Add a version of buffer_xml_printf (defined in gdbsupport/buffer.{c,h})
that appends to an std::string, rather than a struct buffer. Call it
"string" rather than "buffer" since it operates on an std::string rather
than a buffer. And call it "appendf" rather than "printf", since it
appends to and does not replace the string's content. This mirrors
string_appendf.
Place the new version in gdbsupport/xml-utils.h.
The code is a direct copy of buffer_xml_printf. The old version is
going to disappear at some point, which is why I didn't do any effort to
share code.
