Merge commit 'dcf8f259d107838ff3778343dcb762398130a1a3' into release/0.10

* commit 'dcf8f259d107838ff3778343dcb762398130a1a3':
  build: Add 'check' target to run all compile and test targets.
  Ignore generated aviocat tool.
  avconv: only apply presets when we have an encoder.
  flacenc: ensure the order is within the min/max range in LPC order search
  yuv4mpeg: reject unsupported codecs
  vp8: reset loopfilter delta values at keyframes.
  vp56: release frames on error
  vp56: make parse_header return standard error codes
  ivi_common: check that scan pattern is set before using it.
  Prepare for 0.8.5 Release
  x86: Require an assembler able to cope with AVX instructions

Conflicts:
	RELEASE
	avconv.c
