  lavf: zero data/size of the packet passed to read_packet().
  ARM: use 2-operand syntax for ADD Rd, PC in Apple PIC code
  ARM: align PIC offset pools to 4 bytes
  ARM: swap source operands in some add instructions
  configure: update tms470 detection for latest version
  lavf probe: prevent codec probe with no data at all seen
  motion_est: fix use of inline on extern functions
