PVS V1028: cast result of operation instead of operands

If an overflow occurs before the cast, we can't fix it. If we cast
first, we can rely on integer promotion to make the result use the
appropriate size.

- style fixes,
- fix error handling in CamDevice.cpp,
- implemented PowerOnSensor() for Sonix,
- add a ProbeByIICSignature method to CamSensor, that takes a list of regs and values to match, as some Linux drivers do,
- add (unfinished, mostly copied from TAS5110C1B) support for TAS5130D1B sensor,
- add (unfinished) support for PAS106 sensor, probe by IIC signature as the Linux driver does,
- add probing by IIC signature for the HV7131E1 sensor as the Linux driver does,
- use -lusb for BeOS (actually ZETA) builds, don't try to use the Haiku USB Kit,
- for the TAS5110C1B sensor, use remove code dup and call SetVideoFrame(), tweaked the values to match those sniffed from the XP driver,
- disabled gain control for now on sonix, doesn't seem to work on all models.
This gets another sonix-based webcam working, partially at least, so if you want to get one to try until UVC works, try this one:

We should at least have one webcam supported in the alpha :D

- point to logitech opensource website
- cleanup
- handle frame size suggestions (Codycam gets QVGA now, and eXposer doesn't complain), though the picture is not centered nor scaled yet.
- added a stat text parameter to show actual frame rate.

- Finaly got sensor gain to work for mine...
- added brightness and contrast parameters for sn9cxxx according to a linux driver, but doesn't seem to work for mine.

Turns out my QuickCam is not a usual quickcam with an WTV600 chip but an NW80x based one...

- style cleanup (remove // -----, 2 lines between funcs)
- hooks to handle probing sensor chips instead of hardcoding them.
- more urls for reference drivers (the macam driver would be interesting but it's GPL and ObjC :-( )...

- don't hardcode frame size, use the maximum available instead. Setting it at connection won't work yet.
- Added hooks to handle device and sensor-specific parameters
- Added gain controls for my webcam, oddly none seem to work correctly except green gain :^)

Make CamFrame a subclass of BMallocIO to add a timestamp field.
Set the field on allocation and pass it around.
Still disabled as CodyCam drops everything, I should probably drop old frames from the buffer...
for now it uses system_time() to make CodyCam happy.

more Zeta vs Haiku USB Kit cleanup

Current version of my USB Webcam driver. WORK IN PROGRESS!
Uses the USB Kit (userland API, needs libusb) to publish a
media node representing the webcam.
It currently only works with my Sonix webcam (3Euro cheapo
cam), but is modular enough to easily expand it, some code
is already there to detect Quickcams.
For now you should be able to build it under Zeta with the
makefile provided.
Making a Jamfile might get tricky as several source files are
created by the makefile itself to include addons and censors
in the build.
