Replace VEC(gdb_xml_value_s) with std::vector 

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.

gdb/ChangeLog:

	* xml-support.h (struct gdb_xml_value): Add constructor.
	<value>: Change type to unique_xmalloc_ptr.
	(gdb_xml_value_s): Remove typedef.
	(DEF_VEC_O (gdb_xml_value_s)): Remove.
	(gdb_xml_element_start_handler): Change parameter type to
	std::vector.
	(xml_find_attribute): Likewise.
	* xml-support.c (xml_find_attribute): Change parameter type to
	std::vector and adjust.
