av_image_copy() accepts const uint8_t* const * as source;
lots of user have uint8_t* const * and therefore either
cast (the majority) or copy the array of pointers.
This commit changes this by adding a static inline wrapper
for av_image_copy() that casts between the two types
so that we do not need to add casts everywhere else.

The commits eac4324bfb and
cd8211527e renamed the examples, but the
targets were not updated. Hence, the builds are missing -lm.

The contents of this field are not defined for decoding. Use
pkt_timebase, which is the timebase of demuxed packets.
Drop a tautological av_packet_rescale_ts() call, as the stream and
decoder timebases are the same.
Their usefulness is questionable, very few decoders set them, and their type
should have been int64_t. A replacement field can be added later if a valid use
case is found.

Frame counters can overflow relatively easily (INT_MAX number of frames is
slightly more than 1 year for 60 fps content), so make sure we use 64 bit
values for them.
Also deprecate the old 32 bit frame_number attribute.

Add qsv_transcode example which shows how to use qsv to do hardware
accelerated transcoding, also show how to dynamically set encoding
parameters.
examples:
Normal usage:
qsv_transcode input.mp4 h264_qsv output.mp4 "g 60"
Dynamic setting usage:
qsv_transcode input.mp4 hevc_qsv output.mp4 "g 60 asyne_depth 1"
100 "g 120"
This command initializes codec with gop_size 60 and change it to
120 after 100 frames

Previously, the default timebase caused two warnings during decoding about not being able to update timestamps for skipped and discarded samples, respectively.

The last encoded frame is now fetched on EOF. It was previously left in the encoder and caused a "1 frame left in queue" warning.

This comment only applies to the scenario in which one uses
the AVCodecContexts embedded in AVStreams. Yet this code sample
stopped doing so in 9897d9f4e074cdc6c7f2409885ddefe300f18dc7;
and the last major version bump even removed the public
AVCodecContexts in AVStreams. So just remove this comment.

Treat values returned from av_dict_get() as const, since they are
internal to AVDictionary.
