Fixes camera RTE on Windows
The root of the issue was that some cameras / camera drivers don't set
compression type in the bitmap header explicitly to a V4L2_XXX, but set
it to BI_RGB, which is unknown value for frame converters. To fix this,
this CL converts BI_RGB to an appropriate V4L2_XXX value.

Fix problem with using clipboard in Windows camera emulation
This is a fix for a user reported issue #24794. In the nutshell, when emulator grabs
a frame from webcam it leaves its bitmap in the clipboard (which is global). So, when
user does a 'paste' somewhere else, that bitmap will be pasted there. Being bad by
itself, it gets worst, because 'copy / paste' will be globally broken while camera
application is running in the emulator. I.e, if you have camera app running in the
emulator, and at the same time you're editing a Word file (for example), copy / paste
will not work in Word.
This CL contains a fix such as when possible, camera emulator on windows will not use
clipboard to grab video frames, but will grab video frames using frame callback.

Add required frame dimensions for Win and Mac.
Camera framework requires that certain frame dimensions must be supported by the
camera devices. Since on Windows and Mac we have no way of knowing the real
webcam capabilities, but camera API there pretty much allows us to choose any
frame dimensions that we want, we will hard-code those that are required by
the camera framework.

Timeout frame capturing.
It has been observed on some of the MS camera devices, that device may got stuck on something
that would alwais return EAGAIN when queried for the next video frame. This requires us to
timeout the loop that repeats attempts to acquire first frame from the device. Also added
detection and reporting of I/O errors occurred during frame capturing.
Also, this CL contains some cosmetick changes to error and warning reporting.

Fix captured frame pixel format on Windows
Apparently, bitmap obtained through the capXxx + clipboard API is formatted
with BRG, not RGB format.

Implements camera service in emulator
This is fully functional camera service implementation, that works (tested) on both,
Linux and Windows.
Fixed little/big endian bugs in the coverter code. Moved preview frames to use RGB32
instead of RGB565: RGB32 conversions are simpler and faster in the guest.
Made "payload size send" a separate routine
