This patch adds a print_xml_feature visitor class which turns a C target description into xml. Both gdb and gdbserver can do this. An accept function is added to gdbserver tdesc to allow it to use vistor classes. Tests are added to maintenance_check_xml_descriptions which takes each pair of tested descriptions, turns them both into xml, then back again, and confirms the descriptions still match.
