      libavutil: move FFALIGN macro from common.h to macros.h · 50078c1c
      Janne Grunau authored
      Include macros.h explicitly in common.h so that external code using
      FFALIGN does not break. It was already implicitly included through
      version.h. Include macros.h in lls.h and internal.h for FFALIGN.
      lls.h was including common.h only for FFALIGN and internal.h was
      missing the include for FFALIGN. `make checkheaders` did not catch it
      because it's an internal header.

      libavutil: Add av_clip_intp2 · bf07d813
      Peter Meerwald authored
      there already is a function, av_clip_uintp2() that clips a signed integer
      to an unsigned power-of-two range, i.e. 0,2^p-1
      
      this patch adds a function av_clip_intp2() that clips a signed integer
      to a signed power-of-two range, i.e. -(2^p),(2^p-1)
      
      the new function can be used as a special case for av_clip(), e.g.
      av_clip(x, -8192, 8191) can be rewritten as av_clip_intp2(x, 13)
      
      there are ARM instructions, usat and ssat resp., which map nicely to these
      functions (see next patch)
