Define positive return values as non errors and leave further meaning undefined
This allows future extensions to use these values

eval API.
More grep-friendly and more consistent with the rest of the FFmpeg
API.

const_name -> const_names
const_value -> const_values
func[12]_name -> func[12]_names
func[12] -> funcs[12]
All these parameters contain a list of values, using plural names for
them help understanding a little.

containing an error code.
Allow these functions to convey the reason of the failure to the
calling function, failure which is not always due to a parsing error
but it may depend for example on a memory problem.
Also fix several potential memleaks.

ff_parse_and_eval_expr(), place the names for constants/functions
before the corresponding values.
This looks more readable, as the user is expected to know the names
before the values.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

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 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.

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
