-1/+1 somewhat simplifies the values that can be generated by rotary
encoders, and rules out the possibility of batching and more nuanced
movement reporting.
So, we modify the device configuration to allow values other than -1 and
1 to be supported. In order to give the developer a sense of what these
values map to in terms of angular displacement, we also parse a
resolution configuration from the devices IDC file.
This will be specified as:
device.res = xxxx
of type float. If a value is not provided, a default res value of 0.0f
is used.
This patch also adds a per device scaling factor, which is used to
suitably modify the values reported (as well as the resolution) to tune
the input events generated and resulting UI according to the hardware.
This can be specified in the IDC file as:
device.scalingFactor = xxxx
of type float. If a scaling factor is not provided, a default of 1.0f
is used.

This error can be seen for the following use case
1. Connect HDMI display
2. Dump the SurfaceFlinger state
The problem here is that HWComposer would have processed the display
connection event via the hotplug mechanism and considers that the
external display is connected. However, SurfaceFlinger has not
updated its internal state (mDisplays) since it will be waiting for
the mStateLock to be release by the dump function. As a result, when
the dump function invokes the getLayerSortedByZForHwcDisplay for the
external display, we will end up seeing the error log message because
SurfaceFlingers internal state has not yet been updated.
We can move this to ALOGW since it is a non-fatal/recoverable state.

In a4650a5 the concept of a maximum frame number allowance for the consumer was
introduced. A call to acquireBuffers will only return buffers when their frame
number is less-than-or-equal-to this maximum frame number. When SurfaceFlinger
is the consumer, this maximum frame number is calculated in the
onFrameAvailable/onFrameReplaced callbacks. These callbacks are called when a
new buffer is dequeued by the application. The problem is that these callbacks
are called _after_ the fence wait which is used to throttle the frame
production of client apps. When the previous frame needs a long time to draw,
those waits can potentially be a long time. As a result SurfaceFlinger won't do
any composition with the new frame until the wait is over.
Normally this isn't a big problem because there is a queue of buffers for
SurfaceFlinger to work with. However, this changes massively when a client app
is using a swap interval of zero. In this case, a new frame will instantly
replace the previous queued frame. However, SurfaceFlinger doesn't know this
until the onFrameReplaced callback gets called - which is delayed by the fence
wait. If the timing is bad, SurfaceFlinger never gets a chance to pick up a new
frame to do the composition with.
We see this behaviour on our TC development system (slow GPU) with legacy
on-screen benchmarks. Such apps are using a swap interval of zero and sometimes
frames don't get updated for several seconds. This behaviour can be also seen
on a Nexus5, although it isn't as obvious as on our TC.
The fix in this cl is to move the EGL throttling to the end of the queueBuffers
function. This ensures that if a frame gets replaced in the queue, all
consumers who installed the callbacks, get called in a timely fashion.

Reduce transparent region from a layer only if the transparent
region has valid intersection with the layer. Otherwise, reducing
a transparent region lying completely outside of the layer leads to
invalid sourcecrop values for the layer.

Devices like dory get slammed when bugreports are taken and can't
compress all the raft logs in the current 5min timeout. Our dogfooders
spend their precious time getting us bugreports and then we can't act
on them because we have broken raft logs. :(
This change bumps up the timeout in the hopes that we can get complete
logs from even our slowest devices.
