2cbaa078d1 avcodec: use HAVE_THREADS header guards to silence -Wunused-function 
When compiled with --disable-pthreads, e.g
http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7,
a bunch of -Wunused-functions are reported due to missing header guards
around threading related functions.
This patch should silence such warnings.

e0c7ba40cf takdec: pad filter coeff buffer for DSP functions 
Currently, a part of the loop has to be handled in plain C, because of DSP
function requirements of having batches of 16 elements to process.

Instead, pad the buffer with 0 where the DSP functions are overreading.
