Optimize memory consumption in the mp3data parser. The vbr-header parser will never need 1.800 byte of data. The maximum amount of data needed is 1/10 of this.

Avoid magic numbers. Use the available defines to set up the bit mask to compare MPEG frame headers.

Hopefully fix red now and reduce binsize for HWCODEC targets. This change implements a local read_uint32be() function within the mp3data parser.

More robust implementation of MPEG frame header search. The parser will not only search for the very first byte sequence that looks like a valid MPEG frame header. It will search for a valid MPEG frame header sequence, decode it, and probe if there is a consecutive MPEG frame header of the same type (MPEG version, layer, sampling frequency) at the expected position. This approach will reduce false detection of MPEG frame headers in case of errorous metadata or garbaged files. Fixes FS#12007.

Quick fix to allow certain MP3 files to play. If a Xing or Info header didn't properly set both the frame count and byte count, then the bitrate was set to zero, preventing playback. Better to use the bitrate of the first audio frame in this case. (More sanity checking of the frame count should perhaps be done.)
