[PATCH] Use std::string in memory_map_parsing_data

[Simon Marchi <simon dot marchi at ericsson dot com>]

[Woops, I forgot to send this patch.  It should be applied before
 "Get rid of VEC (mem_region)"]

Replace the fixed-size array with a string.

gdb/ChangeLog:

	* memory-map.c (struct memory_map_parsing_data) <property_name>:
	Change type to std::string.
	(memory_map_start_property): Adjust.
	(memory_map_end_property): Adjust.
