Andreas Rheinhardt	a162e78cd5	avcodec/fraps: Use cached bitstream reader This proved beneficial for performance: For the sample [1] the number of decicycles in one decode call decreased from 155851561 to 108158037 for Clang 10 and from 168270467 to 128847479 for GCC 9.3. For x86-32 compiled with GCC 9.3 and run on an x64 Haswell the number increased from 158405517 to 202215769, so that the cached bitstream reader is only enabled if HAVE_FAST_64BIT is set. These values are the average of 10 runs each looping five times over the input.

Andreas Rheinhardt	bc6838deb9	avcodec/fraps: Use unchecked bitstream reader The fraps decoder already checked for overreads manually (and errored out in this scenario), yet it still enabled implicit checks, leading to worse performance and more code size. This commit disables the implicit bitstream reader checks. For the sample [1] this improves performance from 195105896 to 155851561 decicycles for Clang 10 and from 222801887 to 168270467 decicycles when compiled with GCC 9.3. These values are the average of 10 runs each looping ten times over the input.

Reimar Döffinger	cd3ced1bb9	fraps: frame threading support.
