mss2: reindent after last commit
mss2: prevent potential uninitialized reads

The alternative to zeroing on init is setting the corrupted flag in
all cases where pal_pic is not fully written, at the cost of added
complexity.

lavu: rename audioconvert.* to channel_layout.* and deprecate audioconvert.h
Include libavutil/channel_layout.h instead of libavutil/audioconvert.h

Also reorder some other #include when applicable.
x86: Require an assembler able to cope with AVX instructions

All modern assemblers have this capability.  Older NASM versions
that lack the capability produce code that crashes at runtime,
so it's better to error out during the build process instead.

build: Drop AVX assembly ifdefs

An assembler able to cope with AVX instructions is now required.
