Completely removed the old allocation table.
Base everything on the "standard allocation table"
Using allocation table for "standard" frame sizes

Fix for PLC crash when using large frames
Trying not to crash on bit errors
removed stupid code in transient_analysis()
Fixed stupid bug for single-sample bands
Change ec_{enc|dec}_bit_prob to take probabilities in units of 1/65536 instead of 1/256. This allows them to use a single 16x16->32 multiply instead of a 24x8->32 multiply. Also change the time-frequency resolution flag coding to ensure that "0" is always the most-probable symbol (i.e., that prob("1")<50%), as that's where all the rounding error accumulates.
Provide direct implementations ec_{enc|dec}_bit_prob() that do not require a division instead of using the normal entropy coder path. This should be exactly equivalent to the existing code.
