* [c_api] leverage index downcast - make index downcast declaration+definition possible with macros - use macros on existing index types * [c_api] Add IndexLSH to C API * [c_api] Add Index IO interface - new header index_io_c.h for access to the index_io.h API - function`faiss_write_index` and overloads for dumping index to a file - function`faiss_read_index` and overloads for reading index from a file - function`faiss_clone_index` for cloning an index - update C example to save index to a file * [c_api] Add IndexIDMap and IndexShards API
