Andreas Rheinhardt 645f705d6a av(codec|device): Don't cast pointers to int 
C99/C11 6.3.2.3 5: "Any pointer type may be converted to an integer
type. [...] If the result cannot be represented in the integer type,
the behavior is undefined." So stop casting pointers to int; use
uintptr_t instead.

Andreas Rheinhardt 6d484671ec avcodec/dv: Don't initialize RL VLC for encoder 
Said RL VLC is only used by the decoder, ergo don't initialize it for
the encoder and move the whole code and the RL VLC table itself to
dvdec.c.

Andreas Rheinhardt a247ac640d avcodec: Constify AVCodecs 
Given that the AVCodec.next pointer has now been removed, most of the
AVCodecs are not modified at all any more and can therefore be made
const (as this patch does); the only exceptions are the very few codecs
for external libraries that have a init_static_data callback.

Andreas Rheinhardt b25b6432a7 avcodec/dvdec: Don't use restrict directly to fix build on MSVC 
004ebd4b added a function with a parameter that was declared as restrict
and not av_restrict. This is not supported by MSVC as several FATE-boxes
that now fail to build show. So use av_restrict.

Anton Khirnov 7ea1b3472a lavc: deprecate the use of AVCodecContext.time_base for decoding 
When decoding, this field holds the inverse of the framerate that can be
written in the headers for some codecs. Using a field called 'time_base'
for this is very misleading, as there are no timestamps associated with
it. Furthermore, this field is used for a very different purpose during
encoding.

Add a new field, called 'framerate', to replace the use of time_base for
decoding.
