7f971e0176 Fix FS#10476. Prevent FLAC bitrate calculation overflow with large files. The watermark depends on the bitrate, and so this also fixes playback pauses on large FLAC files.

04be8dd7fe Fix inaccurate time display for 44.1 (and 22.05) kHz MP3 audio tracks. Time was off by about 0.2%. Doesn't sound much, but after one hour, that's 8 seconds. Also fix a problem when seeking to near the end of a file.

b957f7214b Rearrange the MDCT library lookup tables so that codecs can access them. Access them in cook. Remove old cook trig tables. Replace old 32x16 bit fixed point multiply code with faster ASM ARM/Coldfire versions using full 32 bit precision. Improves performance signficantly on PP5024 (~200% realtime for a 64k file) while saving a lot of memory and improving accuracy.

b5b9cb031d Modified the code for seeking to speed it up a bit. Instead of searching 
the file for the required timestamp, we seek directly to a calcualted 
position. If we go to a point beyond the desired seek_time, we seek back 
in blocks (normally one or two blocks to the back) to get the required 
block.
