893669cc10 Rather obvious simplification of the mpeg frametime fraction calculation.

ba966c1761 Archos recording/playback: (1) Xing header creation: * Now estimates the framecount from the recording time if the MAS frame counter saturates, so it always writes a valid Xing header. * Reverted my brainless short-xing-header change. This was only valid for layer 3. (2) Xing/VBRI header evaluation: Fixed possible overflow in bitrate calculation. (3) MPEG thread: Avoid double chunk size limiting for the rare case of 8 MB modded Ondios.

ec9b202a92 Reworked handling of MPEG audio frame & file info: * Fixed frame size calculation for layer 1 (all versions) and layer 2 (V2/V2.5). * Exact frame time (expressed as a fraction) for way more precise playtime calculation at 44100/22050/11025Hz sample frequency. * Exact playtime<->position conversion for CBR also used for resume position. * More compact code, long policy.

9352ac8668 Archos recording: Always prepend ID3V2 and Xing header to a recording file, even with prerecording and file splitting. Adjusted Xing header creation to create smaller headers. Fixed missing break; in the mpeg thread.

5c2c991d14 Applied patch "[ 1232957 ] MP3 metadata fixes for software codec". 
Thanks to Magnus Holmgren. Now metadata reading is better with
improved performance for mp3 files.

509117db90 (1) Bugfix: create_xing_header() now returns 0 in case of an invalid header template, i.e. when mp3headerinfo() returns false. It used to return a random number, causing all sorts of problems. This was the cause for the end of a recording (still in the buffer) occasionally overwriting the beginning. (2) Some code cleanup.
