019ab88a95 lavc: add an option for exporting cropping information to the caller 
Also, add generic code for handling cropping, so the decoders can export
just the cropping size and not bother with the rest.

9488032e10 libavformat/avio: Add avio_get_dyn_buf function 
This commit adds the avio_get_dyn_buf function which allows accessing
the
content of a DynBuffer without destroying it.

This is required in matroskaenc for preliminary writing (correct) mkv
headers.

Context for this change is fixing regression bug #5977.

775a8477b7 hwcontext_vaapi: add a quirk for the missing MemoryType attribute 
The Intel binary iHD driver does not support the
VASurfaceAttribMemoryType, so surface allocation will fail when using
it.

a8d51bb424 hwcontext_vaapi: Add driver quirks to the hwdevice 
The driver being used is detected inside av_hwdevice_ctx_init() and
the quirks field then set from a table of known device.  If this
behaviour is unwanted, the user can also set the quirks field
manually.

Also adds the Intel i965 driver quirk (it does not destroy parameter
buffers used in a call to vaRenderPicture()) and detects that driver
to set it.

d06aa24ba5 hwcontext: Hardware frame mapping 
Adds the new av_hwframe_map() function, which allows mapping between
hardware frames and normal memory, along with internal support for
implementing it.

Also adds av_hwframe_ctx_create_derived(), for creating a hardware
frames context associated with one device using frames mapped from
another by some hardware-specific means.
