Several ioctl calls were returning -1 instead of -errno,
which may confuse upper layers, especially when the error
is -ENOMEM. Also move some existing "err = -errno" calls
to the top of if statements so that errno cannot change
by libc calls in the error handling code.

If there is a SKIP layer present, the SKIP layers are first composited
using the GPU. If there any layer below the SKIP layer that performs
any operations on the FrameBuffer, it results in undesireable results
on the screen e.g. artifacts, since SurfaceFlinger draws the SKIP layers
before the HWComposer.

A Google modification to eglCreateWindowSurface was
causing SurfaceFlinger to set its swap interval
value back to 1, regardless of the value set in the

This patch modifies the fb_setSwapInterval function

property and not change the swap interval if a value
is set there.

This is a helper function that will return false if the given format is
supported by adreno drivers but not supported in GPU HW. For these
formats, adreno will use software color conversion routines to convert
them to acceptable format by the GPU HW. This may be required if we
want to avoid creating texture for certain formats when not absolutely
necessary. Could be defaulted to return true depending on a compile
time flag.

The x and y coordinates are derived properly from clip and dest rect with this fix.
- Even if rotation is involved, we need to start reading from the same point.
- Do scaling operation on the delta, and then add the source left and top values.
- If we scale the result of addition, we will not be reading source correctly.
