This enables SIMD optimisations of this function.

ff_parse_and_eval_expr().

Change func[12] attributes from "** func" to "* const * func".

This is consistent with the semantics of the provided arrays of
functions, which are not supposed to be changed by the ff_parse_*
functions.

Also fix the GCC compilation warnings:
libavcodec/ratecontrol.c: In function ‘ff_rate_control_init’:
libavcodec/ratecontrol.c:109: warning: passing argument 3 of ‘ff_parse_expr’ discards qualifiers from pointer target type
libavcodec/eval.h:69: note: expected ‘double (**)(void *, double)’ but argument is of type ‘double (* const*)(void *, double)’

ff_parse_and_eval_expr().

Change attribute from "const char **" to "const char * const *".
The name arrays are not supposed to be changed by the function.

The new name is more expressive and fits better in the overall naming
scheme for the revisited eval API.

This reorders the lfe_fir tables, and drops the mirrored half,
such that the loops in lfe_interpolation_fir() can be simplified.
The new loop structure should be easier to implement with SIMD.
Static data size is reduced by 2kB.
3% faster on Cortex-A8.

This way we have to deal only with struct AVExpr and AVExpr, which is
slightly less confusing as the association between the two symbols is
obvious.
