Previously the calculation computed Y for each region before returning the weighted average, which "baked in" the over-importance of small statistics regions. The revised calculation will treat all pixels equally when the region weights are the same, making it easier to use. With the previous scheme, proper "average" metering was difficult to implement.

This commit plumbs the user transform from the Raspberry Pi pipeline handler through to the IPA.

A few minor tweaks make sense along with this: * Reset the lambda values when we reset everything. It wouldn't make sense to re-start with the old mode's values. * Use the last recorded colour temperature to generate new tables rather than any default value. * Set the frame "phase" counter to ensure the adaptive procedure will run asap.

This fixes a bug where the luminance correction table was not being resampled according to the camera mode, in the same way as the colour tables. This could be noticeable if any camera modes crop aggressively. This resampling can be done "up front" in the SwitchMode, as we have only a single fixed luminance table. In order to protect the recalculation of the table from the asynchronous thread (which reads it) I've elected to wait for that thread to go idle (though I doubt it would have mattered much). As a by-product of stopping the thread, it no longer needs its own copy of the camera mode (async_camera_mode_).

For example it's possible that the exposure profile could be changed by the application so the division between exposure time and analogue gain may be different. The other underlying reason (and which this commit accomplishes too) is that the sensor's line timing may change in a new mode, and because V4L2 drivers store a number of exposure _lines_, the resulting _time_ will "change under our feet".
