+Subject: Check the size before reading with mad_bit_read
+
+There are various cases where it attemps to read past the end of the buffer
+using mad_bit_read(). Most functions didn't even know the size of the buffer
+they were reading from.

+Subject: Check the size of the main data
+
+The main data to decode a frame can come from the current frame and part of the
+previous frame, the so called bit reservoir. si.main_data_begin is the part of
+the previous frame we need for this frame. frame_space is the amount of main
+data that can be in this frame, and next_md_begin is the part of this frame that
+is going to be used for the next frame.
+
+The maximum amount of data from a previous frame that the format allows is 511
+bytes. The maximum frame size for the defined bitrates is at MPEG 2.5 layer 2
+at 320 kbit/s and 8 kHz sample rate which gives 72 * (320000 / 8000) + 1 = 2881.
+So those defines are not large enough:
+ # define MAD_BUFFER_GUARD      8
+ # define MAD_BUFFER_MDLEN      (511 + 2048 + MAD_BUFFER_GUARD)
+
+There is also support for a "free" bitrate which allows you to create any frame
+size, which can be larger than the buffer.
+
+Changing the defines is not an option since it's part of the ABI, so we check
+that the main data fits in the bufer.
+
+The previous frame data is stored in *stream->main_data and contains
+stream->md_len bytes. If stream->md_len is larger than the data we
+need from the previous frame (si.main_data_begin) it still wouldn't fit
+in the buffer, so just keep the data that we need.
