6a7c4d60a1 lavu/float_dsp: add double-precision scalar product
The function pointer is appended to the structure for backward binary
compatibility. Fortunately, this is allocated by libavutil, not by the
user, so increasing the structure size is safe.

c00cd007e8 configure: Remove av_restrict
All versions of MSVC that support C11 (namely >= v19.27)
also support the restrict keyword, therefore av_restrict
is no longer necessary since 75697836b1.

a6c10d05fe lavu/floatdsp: RISC-V V vector_fmul_scalar
This is based on existing code from the VLC git tree with two minor
changes to account for the different function prototypes.

2e4130037c float_dsp: Include config.h for redefining restrict
This makes sure that the restrict keyword is mapped to whatever
keyword the compiler prefers/supports. This fixes building on MSVC
(and possibly on GCC 2.x as well).

Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.
