d86f698e38 avcodec/mips: [loongson] optimize theora decoding in vp3dsp. 
Optimize theora decoding with msa in functions:
1. ff_vp3_idct_add_msa
2. ff_vp3_idct_put_msa
3. ff_vp3_idct_dc_add_msa
4. ff_vp3_v_loop_filter_msa
5. ff_vp3_h_loop_filter_msa
6. ff_put_no_rnd_pixels_l2_msa

Theora decoding speed improved about 36%(from 22fps to 30fps, Tested on loongson 2K1000).

c822d70c3d Fix usage of temp_file flag in hls_flags option. 
This is a regression introduced by 223d2bde22.
It appears that regression was introduced in 4.1, 4.0.x does not share
this behaviour.

Temp files were not created for MPEG-TS segments options - HLS_TEMP_FILE
flag was never set on AVFormatContext, it is however set on HLSContext object.
In order to fix this issue, proper flags field must be checked. In addition,
renaming code was messed up and apparently was working only for MP4 files.

f652c7a45c avcodec/mips: Fix failed case: hevc-conformance-AMP_A_Samsung_* when enable msa 
The AV_INPUT_BUFFER_PADDING_SIZE has been increased to 64, but the value is still 32
in function ff_hevc_sao_edge_filter_8_msa. So, use AV_INPUT_BUFFER_PADDING_SIZE directly.
Also, use MAX_PB_SIZE directly instead of 64. Fate tests passed.
