Add new plist_mem_free() function

Thanks to @azerg for bringing this to my attention.

Instead of having multiple (internally identical) plist_*_free() functions,
this commit introduces a single plist_mem_free() that can be used to free
the memory allocated by plist_to_xml(), plist_to_bin(), plist_get_key_val(),
plist_get_string_val(), and plist_get_data_val().
Note: This commit REMOVES plist_to_bin_free() and plist_to_xml_free().
