Add adaptive_i/b feature to hevc_qsv. Adaptive_i allows changing of
frame type from P and B to I. Adaptive_b allows changing of frame type
frome B to P.

Add "slice" intra refresh type to h264_qsv and hevc_qsv. This type means
horizontal refresh by slices without overlapping. Also update the doc.

There are still some bugs unresolved in HEVC decoding. The
checkasm-hevc-pel test failed. It's suggested to repair together.

Qsv decoder only supports directly output nv12 and p010 to system
memory. For other format, we need to download frame from qsv format
to system memory. Now add other supported format to qsvdec.

Qsv encoder only support input P010 and nv12 format directly from system
memory. For other format, we need to upload frame to device memory and
input qsv format to encoder. Now add other system memory format support
to qsv encoder.

To do more accurate QP control, add min/max QP control on I/P/B frame
separately to qsv encoder. qmax and qmin still work but newly-added
options have higher priority.
