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).

Prior to this it was possible that format reduction was ended
before it fully propagated leading to failure later in picking
formats.
No testcase with unmodified source exists, the case was reproduced
with less aggressive list merging though.

Revert "avformat/utils: Close codec context since it is allocated by avformat_new_stream in refrence to ticket 2716"

This causes a race condition with VLC. Its plausible that other
applications also would have races with it and its just fixing a memleak when
the user application forgets to free the codec. It causes more
problems than it solves in its current form, thus the revert.
Better solutions are welcome

This reverts commit 0f229f9b.

This matches the matroska defintion of stereo_mode, with

avformat/utils: Close codec context since it is allocated by avformat_new_stream in refrence to ticket 2716

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.
