options: support parsing values into substructs
Add an alternate mode for option parser objects (struct m_config) which is not inherently tied to any particular instance of an option value struct. Instead, this type or parsers can be used to initialize defaults in or parse values into a struct given as a parameter. They do not have the save slot functionality used for main player configuration. The new functionality will be used to replace the separate subopt_helper.c parsing code that is currently used to parse per-object suboptions in VOs etc. Previously, option default values were handled by initializing them in external code before creating a parser. This initialization was done with constants even for dynamically-allocated types like strings. Because trying to free a pointer to a constant would cause a crash when trying to replace the default with another value, parser initialization code then replaced all the original defaults with dynamically-allocated copies. This replace-with-copy behavior is no longer supported for new-style options; instead the option definition itself may contain a default value (new OPTDEF macros), and the new function m_config_initialize() is used to set all options to their default values. Convert the existing initialized dynamically allocated options in main config (the string options --dumpfile, --term-osd-esc, --input=conf) to use this. Other non-dynamic ones could be later converted to use this style of initialization too. There's currently no public call to free all dynamically allocated options in a given option struct because I intend to use talloc functionality for that (make them children of the struct and free with it).
