68dacb4e3b ARM: check struct offsets only when they are used 
The offsets differ depending on configuration, so only check them when
they will actually be used.  Presently, this is when NEON is enabled.

9711439b44 Cosmetics: rename ff_parse_expr() and ff_parse_and_eval_expr() parameters: 
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.

9ace13b416 Make ff_parse_expr() and ff_parse_and_eval_expr() return an int 
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.

such.

Also put the [3][0][0][0] codec tag, mapped to rgb565le, in a special
section. It needs to be specified *after* the nut RGB[16] codec tag,
otherwise it will be used by default when encoding normal non-flipped
rgb565le, and will be decoded like a flipped format (see
rawdec.c:raw_init_decoder()).

473147bed0 Switch some ints to unsigned (they can only have positive values, this allows 
compiler to optimize some math from mul/div to shr/shl). Also add a cast to
uint32_t when calling decodeplane32(), this silences a compiler warning.
Lastly, in decodeplane8/32(), flatten a double-loop into a single-loop and
calculate the length once before entering the loop instead of during every
iteration (since it doesn't change).

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

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
