92fc0bfa54 avutil/mips: refactor msa SLDI_Bn_0 and SLDI_Bn macros. 
Changing details as following:
1. The previous order of parameters are irregular and difficult to
   understand. Adjust the order of the parameters according to the
   rule: (RTYPE, input registers, input mask/input index/..., output registers).
   Most of the existing msa macros follow the rule.
2. Remove the redundant macro SLDI_Bn_0 and use SLDI_Bn instead.

77937a42e7 lavc/videotoolboxdec: fix crop handling when multithreaded 
This was partially fixed by 233cd89, but it made changes to AVFrame fields
from within end_frame, which doesn't work consistently when multithreading
is enabled. This is what the post_process function is for.

1a066d87e3 avformat/hlsenc: Fix memleak when using single_file 
This commit fixes a memleak in the hls muxer when one uses a single file
as output. It has been forgotten to free the temporary buffers used to write
the packets so that the size of the leaks basically amounts to the size
of the output file. This commit adds the necessary free.
