[v4l-utils,v1,0/3] media-ctl: Add support for subdev TRY state

Hello,

This small patch series extends media-ctl to support subdev TRY states.
Doing so allows retrieving the default state of subdevs, or trying
configurations.

The approach is quite straightforward: patch 1/3 replaces the hardcoded
ACTIVE state in libv4l2subdev with a 'which' argument, patch 2/3 does
the same for the internal functions of media-ctl, and patch 3/3 adds a
-W/--which argument to media-ctl. When the argument is not set, the
ACTIVE state is selected, preserving the existing behaviour.
