fc7e2d34cf Fix constness for func[12] parameters in ff_parse_expr() and 
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)’

82fdcd449c Change constness for func[12]_name parameters of ff_parse_expr() and 
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.

1235429c27 Rename ff_parse() to ff_parse_expr(). 
The new name is more expressive and fits better in the overall naming
scheme for the revisited eval API.

766fefe8e2 DCA: simplify lfe_interpolation_fir() 
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.

a3731cadfc Avoid the use of the symbol ff_expr_s for referencing AVExpr. 
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.
