c02efacc8f arm: intreadwrite: revert 16-bit load asm to old version for gcc < 4.6 
Commit adebad0 "arm: intreadwrite: fix inline asm constraints for gcc
4.6 and later" caused some older gcc versions to miscompile code.
This reverts to the old version of the code for these compilers.

58b2e0f0f2 vqavideo: return error if image size is not a multiple of block size 
The decoder assumes in various places that the image size
is a multiple of the block size, and there is no obvious
way to support odd sizes.  Bailing out early if the header
specifies a bad size avoids various errors later on.

Fixes CVE-2012-0947.

This avoids returning duplicate timestamps for multiple packets when the
demuxer does not provide all timestamps and packet duration is not known.

Compared to av_opt_ptr, accessors bring:

- better performance (negligible);
- compile-time type check;
- link-time existence check
  (or at worst, a dynamic linker error instead of a NULL dereference).
