This patch adds a new option to the scale filter which ensures that the output resolution is divisible by the given integer when used together with `force_original_aspect_ratio`. This works similar to using `-n` in the `w` and `h` options. This option respects the value set for `force_original_aspect_ratio`, increasing or decreasing the resolution accordingly. The use case for this is to set a fixed target resolution using `w` and `h`, to use the `force_original_aspect_ratio` option to make sure that the video always fits in the defined bounding box regardless of aspect ratio, but to also make sure that the calculated output resolution is divisible by n so in can be encoded with certain encoders/options if that is required.

Changing details as following: 1. Remove the local variable 'out_m' in 'CLIP_SH' and store the result in source vector. 2. Refine the implementation of macro 'CLIP_SH_0_255' and 'CLIP_SW_0_255'. Performance of VP8 decoding has speed up about 1.1%(from 7.03x to 7.11x). Performance of H264 decoding has speed up about 0.5%(from 4.35x to 4.37x). Performance of Theora decoding has speed up about 0.7%(from 5.79x to 5.83x). 3. Remove redundant macro 'CLIP_SH/Wn_0_255_MAX_SATU' and use 'CLIP_SH/Wn_0_255' instead, because there are no difference in the effect of this two macros. Reviewed-by:

Up until now, when performing a SEEK_END seek, the subfile protocol ignored the desired position (relative to EOF) and used the current absolute offset in the input file instead. And when performing a SEEK_CUR seek, the current position has been ignored. Signed-off-by:Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

gcc 6.x and 7.x generate wrong code for little endian machines for the vec_lvsl/vec_perm instruction combos in some cases. The bug was fixed in version 8.x If these instructions are replaced with vec_xl, the problem goes away for all versions of the compilers. Fixes ticket #7124.

This may break some valid tiff files, it appears the specification does not require the offsets to be increasing. They increase in the 2 test files i have though except the last offset which is 0 (an end marker) and for which a special case is added to avoid asking for a sample for that end marker.
