Tracing the state of the voltage and current regulators enables a developer
to attribute power consumption measurements to specific perhipherals and
cores. Unlike other indirect methods of tracing when peripherals and cores
are toggled, the regulator ftrace event indicates the exact point in time
when the kernel switches on or off the device. For example, in the following
trace, a developer can see exactly when the krait2 core starts receiving
power, and and when the voltage is set for voltage scaling.

Some time before kitkat, a workaround was put in place to keep tuna
working with obsolete PowerVR GPU drivers. The tuna product was dropped
in AOSP for kitkat, but the workaround remained.
There are still a number of devices shipping with OMAP4 processors, and
this workaround continues to be applied on those products even when it
is not required. The effect is that virtual display CTS will fail on
those devices.
This option doesn't work with the current selinux protections and
doesn't serve much of a purpose. You can get the same results running
this:

Change-Id: Icc76200df33dc708e30c556ec8a0f393f995fe7c
Implemented these changes:
- Make this code C++.
- Avoid hangs by adding a timeout.
- Add the necessary TEMP_FAILURE_RETRY calls.
- Restructure the code a bit.

Avoid ambiguity by using register numbers. Register names are
interpreted depending on the ABI. Fixes the issue with mips64 gcc,
where registers t0-t4 are translated into $8-$11 (o32 ABI) instead
of $12-$15 (o64 ABI).
Also, use t9 ($25) for storing function address
(in getProcAddress.cpp).
Change-Id: I12ef5cd98bf14dab3c01f2756889cc02856c1cd8
Combines 4 patches by Dragoslav and Douglas:
Use t9 to hold the address of the called function.
Add support for gl binding.
Fix inline assembly code to be R6 compatible.
Fix some more inline assembly code to be R6 compatible.

Use the native stack dumping functions that allows time outs. If
debuggerd locks up, before a bugreport would hang forever. Now
it will timeout properly and still get all of the other information.

When compiling 32 bit binaries against a 64 bit binder interface,
implicit promotions of intptr_t types to uint64_t for fields in the
binder ioctl structures can result in invalid pointers because of sign
extension.
Rather than trying to acquire the state lock without waiting three
times at 1 second intervals in SurfaceFlinger::dump(), just try to
acquire the lock once with a 1 second timeout. Avoids spurious mutex
acquire failures that lead to flaky
com.android.cts.jank.opengl.CtsHostJankOpenGl results.

This code doesn't need to run on the Mac, and the BoringSSL transition
will be easier without references to external/openssl.

Remove generated cpp/h files for gltrace.proto as we can use the build
system to generate these dynamically.
