Renamed lzma_options_simple to lzma_options_bcj in the API.

The internal implementation is still using the name "simple".
It may need some cleanups, so I look at it later.

+/**
+ * \brief       Options for BCJ filters
+ *
+ * The BCJ filters never change the size of the data. Specifying options
+ * for them is optional: if pointer to options is NULL, default value is
+ * used. You probably never need to specify options to BCJ filters, so just
+ * set the options pointer to NULL and be happy.
+ *
+ * If options with non-default values have been specified when encoding,
+ * the same options must also be specified when decoding.
+ *
+ * \note        At the moment, none of the BCJ filters support
+ *              LZMA_SYNC_FLUSH. If LZMA_SYNC_FLUSH is specified,
+ *              LZMA_OPTIONS_ERROR will be returned. If there is need,
+ *              partial support for LZMA_SYNC_FLUSH can be added in future.
+ *              Partial means that flushing would be possible only at
+ *              offsets that are multiple of 2, 4, or 16 depending on
+ *              the filter, except x86 which cannot be made to support
+ *              LZMA_SYNC_FLUSH predictably.
