Add new output-only formats and Define constants for the different plist formats
This commit introduces constants for the different plist formats, and adds 3 new human-readable output-only formats: - PLIST_FORMAT_PRINT: the default human-readable format - PLIST_FORMAT_LIMD: "libimobiledevice" format (used in ideviceinfo) - PLIST_FORMAT_PLUTIL: plutil-style format Also, a new set of write functions has been added: - plist_write_to_string - plist_write_to_stream - plist_write_to_file Plus a simple "dump" function: - plist_print See documentation for details.
