checkasm: store and associate contexts with functions and use it for av_tx
The issue is the following:
- checkasm/av_tx.c initializes a context and a function
- check_func() receives the function only and returns NULL
- checkasm/av_tx.c runs again with a different CPU flag and creates a new
funct
This series solves some outstanding bugs in the dshow device, implements
get_device_list so that `ffmpeg -sources dshow` works and adds logic to
select a video format with extended color information (color range,
space, etc) if exposed by the device.

list_options true would crash when both a video and an audio device were
specified as input. Crash would occur on line 784 because

the list_devices option of dshow didn't indicate whether a specific

Importantly, this now
An avdevice, regardless of whether its category says its an audio or
video device, may provide access to devices providing different media
types, or even single devices providing multiple media types. Also, some
devices may provide no media types. dshow is an example encompassing all
of these cases
The list returned by get_device_list now contains info about what media
type(s), if any, can be provided by each device.
