1ae44c87c9 lavfi/gradfun: remove rounding to match C and SSE code. 
There is no noticable benefit for such precision.

38a2f88d39 lavfi/gradfun: fix dithering in MMX code. 
Current dithering only uses the first 4 instead of the whole 8 random values.

2d66fc543b lavfi/gradfun: fix rounding in MMX code. 
Current code divides before increasing precision.

Also reduce upper bound for strength from 255 to 64.  This will prevent
an overflow in the SSSE3 and MMX filter_line code: delta is expressed as
an u16 being shifted by 2 to the left. If it overflows, having a
strength not above 64 will make sure that m is set to 0 (making the
m*m*delta >> 14 expression void).

A value above 64 should not make any sense unless gradfun is used as
a blur filter.

8b9a153ef3 lavfi/gradfun: do not increment DC pointer for odd values. 
First DC is only used once otherwise. This also makes the code
consistent with ASM versions.

c6831e2a70 wavpack: check K, fix assertion failure 
Instead of this it would be possible to change the code to support
larger K but that would make the code slower and probably still need
checks on K.
This variant is choosen as there are no known valid files that need
larger K

ad04025987 win32: Make ff_win32_open more robust 
- Make MultiByteToWideChar fail when it encounters invalid encoding.
  Without this, invalid characters might just be skipped
- When MultiByteToWideChar fails, assume the file name is in CP_ACP
  and open it via normal open function, even when the file will be
  written
- When malloc fails return error instead of crashing

05fa79b844 hwaccel: fix use with frame based multithreading 
Allows use of AVHWAccel based decoders with frame based multithreading.
The decoders will be forced into an non-concurrent mode by delaying
ff_thread_finish_setup() calls after decoding of the current frame
is finished.

This wastes memory by unnecessarily using multiple threads and thus
copies of the decoder context but allows seamless switching between
hardware accelerated and frame threaded software decoding when the
hardware decoder does not support the stream.

AVBuffers are still bogus since AVFrame does not hold frame data when
