Make channel layout masks unsigned
...
It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.
Fixes a few invalid shifts.

ac3enc: separate exponent bit counting from exponent grouping.

Move bit counting to the bit allocation function. Move exponent grouping to
after bit allocation. This will allow for adjustment of bandwidth parameters
during bit allocation without having to do exponent grouping multiple times.

eac3enc: use frame exponent strategy when applicable.
...
This checks if the set of selected exponent strategies for all blocks in a
channel are in the frame exponent strategy table, and if so, writes the
table index instead of each strategy. This saves up to 7 bits per channel per
frame, so the overall effect on quality is small.

ac3enc: merge AC3MDCTContext with AC3EncodeContext.

Since both the fixed-point and floating-point encoders use the FFTContext,
this no longer needs to be in a separate context. Also, when a short-transform
context is added, the same MDCT window will be used.

ac3enc: Remove bit allocation fallbacks.

They introduce too much complexity for very little benefit. The result is that
