Missing AVInputFormat.get_device_list() for dshow and avfoundation

Description
Rationale: We are writing a C library to enumerate devices programmatically.
Currently one can pass the option -list_devices to the ffmpeg executable and this is handled in libavdevice/dshow.c:dshow_read_header() and libavdevice/avfoundation.m:avf_read_header(), but this is not accessible by API (we get "function not implemented" when invoking avdevice_list_devices()).
Would it make sense to separate this code out to a separate function dshow_get_device_list() and assign it to ff_dshow_demuxer.get_device_list? Similarly for avfoundation?
Should we go ahead and then mail a patch or a git merge proposal to ffmpeg-devel?

API already provides way to access this information.

Sorry for ignoring this ticket so long!
You should be able to use an av_option to get the same output as the ffmpeg executable. If you feel that your solution is superior please feel free to send a patch to the development mailing list.
