Original commit message from CVS: * gst/matroska/ebml-ids.h: Add ID for EBML CRC32 elements. * gst/matroska/Makefile.am: * gst/matroska/ebml-read.c: (gst_ebml_finalize), (gst_ebml_read_class_init), (gst_ebml_read_peek_bytes), (gst_ebml_read_get_length), (_ext2dbl), (gst_ebml_read_float), (gst_ebml_read_header): Support reading 80bit floats, add finalize method to clean up in any case, support reading length/id elements with any length as long as it's smaller than our supported maximum, don't leak buffers if reading as much data as we wanted failed and some smaller cleanup.
