After using the new VIDIOC_DBG_G_CHIP_NAME ioctl I realized that the matching
by name possibility is useless. Just drop it and rename MATCH_SUBDEV_IDX to
just MATCH_SUBDEV.
The v4l2-dbg utility is much better placed to match by name by just enumerating
all bridge and subdev devices until chip_name.name matches.

Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl.
This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done
by the name or index of subdevices or an index to a bridge chip. Most of this
can all be done automatically, so most drivers just need to provide get/set
register ops.
In particular, it is now possible to get/set subdev registers without
requiring assistance of the bridge driver.

This patch adds a helper function that allows to modify range,
i.e. minimum, maximum, step and default value of a v4l2 control,
after the control has been created and initialized. This is helpful
in situations when range of a control depends on user configurable
parameters, e.g. camera sensor absolute exposure time depending on
an output image resolution and frame rate.
v4l2_ctrl_modify_range() function allows to modify range of an
INTEGER, BOOL, MENU, INTEGER_MENU and BITMASK type controls.

Judging from what drivers do and from my experience temeperframe
fraction is set in seconds - look e.g. here
    static int bttv_g_parm(struct file *file, void *f,
                                    struct v4l2_streamparm *parm)
    {
            struct bttv_fh *fh = f;
            struct bttv *btv = fh->btv;
            v4l2_video_std_frame_period(bttv_tvnorms[btv->tvnorm].v4l2_id,
                                        &parm->parm.capture.timeperframe);
    ...
    void v4l2_video_std_frame_period(int id, struct v4l2_fract *frameperiod)
    {
            if (id & V4L2_STD_525_60) {
                    frameperiod->numerator = 1001;
                    frameperiod->denominator = 30000;
            } else {
                    frameperiod->numerator = 1;
                    frameperiod->denominator = 25;
            }
and also v4l2-ctl in userspace decodes this as seconds:
    if (doioctl(fd, VIDIOC_G_PARM, &parm, "VIDIOC_G_PARM") == 0) {
            const struct v4l2_fract &tf = parm.parm.capture.timeperframe;

                            (1.0 * tf.denominator) / tf.numerator,

This patch drops the _ACTIVE part from the selection target names
as a prerequisite to unify the selection target names across the subdev
and regular video node API.

The meaning of V4L2_SEL_TGT_*_ACTIVE and V4L2_SUBDEV_SEL_TGT_*_ACTUAL
selection targets is logically the same. Different names add to confusion
where both APIs are used in a single driver or an application. For some
system configurations different names may lead to interoperability issues.

For backwards compatibility V4L2_SEL_TGT_CROP_ACTIVE and
V4L2_SEL_TGT_COMPOSE_ACTIVE are defined as aliases to V4L2_SEL_TGT_CROP
and V4L2_SEL_TGT_COMPOSE. These aliases will be removed after deprecation

Yuck. The VIDIOC_(TRY_)DECODER_CMD ioctls already had ioctl numbers 96 and 97,
and after merging the timings API I forgot to continue numbering from 98. So
now we have two ioctls with number 96 and two with 97.

With the new table-driver ioctl handling in v4l2-ioctl.c it is essential that
each ioctl has its own unique number, so let's fix this quickly for 3.5.
