This is similar to int32_to_float_fmul_scalar, but
loads a new scalar multiplier every 8 input samples.
This enables the use of much larger input arrays, which
is important for pipelining on some CPUs (such as
ARMv6).

libx264 has a few data exports which require X264_API_IMPORTS
to be defined if we link to libx264 dynamically on Windows.
In a similar fashion to how we handle our compat snprintf
implementation, if we define it all the time, the compiler
will first try and link to __imp_x264_symbol_name, and failing
that, as in the case of a static libx264, will attempt to link
to the non-prefixed symbol, which has already been pulled in by
other x264 functions' object files.

This was handled properly in the normal return case at the end
of the function, but not in this special case.
Returning a value larger than the input packet size can cause
problems for certain library users.
Returning the actual input buffer size unconditionally, since
it is not guaranteed that frame_size is set to a sensible
value at this point.

A frame marked FRAMETYPE_NULL cannot be scalable and requires a
previous frame successfully decoded.

If the channel mapping map multiple output channels to one
input channel, we should only increment the actual pointer once.

The faulty values rippled further down the codepath causing a
hard-to-track segfault in the assembly code.
