Replace VEC(gdb_xml_value_s) with std::vector

Browse source 
This patch replaces VEC(gdb_xml_value_s), which is passed to XML
visitors, with an std::vector.  In order to be able to remove the
cleanup in gdb_xml_parser::start_element, the gdb_xml_parser structure
is made to own the value with a gdb::unique_xmalloc_ptr.

This patch has been tested on the buildbot.

	<value>: Change type to unique_xmalloc_ptr.
