Move all the examples from the talk directory into the webrtc examples directory.
Significant changes:
- move the libjingle_examples.gyp file into webrtc directory.
- rename talk/examples/android to webrtc/examples/androidapp to avoid name conflicts.
- update paths in talk/libjingle_tests.gyp to point to webrtc directory for Objective-C test.

+This directory contains an example Android client for https://apprtc.appspot.com
+
+Prerequisites:
+- "Getting the code" on http://www.webrtc.org/native-code/android
+- Set up webrtc-related GYP variables:
+ export GYP_DEFINES="build_with_libjingle=1 build_with_chromium=0 libjingle_java=1
+ OS=android $GYP_DEFINES"
+ To cause WEBRTC_LOGGING to emit to Android's logcat, add enable_tracing=1 to
+ the $GYP_DEFINES above.
+- When targeting both desktop & android, make sure to use a different output_dir
+ value in $GYP_GENERATOR_FLAGS - for example
+ export GYP_GENERATOR_FLAGS="$GYP_GENERATOR_FLAGS output_dir=out_android"
+ or you'll likely end up with mismatched ARM & x86 output artifacts.
+ If you use an output_dir other than out/ make sure to modify the command-lines
+ below appropriately.
+- Finally, run "gclient runhooks" to generate Android-targeting .ninja files.
+
+Example of building & using the app:
+
+cd <path/to/webrtc>/src
+ninja -C out/Debug AppRTCDemo
+adb install -r out/Debug/apks/AppRTCDemo.apk
+
+In desktop chrome, navigate to https://apprtc.appspot.com and note the r=<NNN> room
+this redirects to or navigate directly to https://apprtc.appspot.com/r/<NNN> with
+your own room number. Launch AppRTC on the device and add same <NNN> into the room name list.
+
+You can also run application from a command line to connect to the first room in a list:
+adb shell am start -n org.appspot.apprtc/.ConnectActivity -a android.intent.action.VIEW
+This should result in the app launching on Android and connecting to the 3-dot-apprtc
+page displayed in the desktop browser.
+To run loopback test execute following command:
+adb shell am start -n org.appspot.apprtc/.ConnectActivity -a android.intent.action.VIEW --ez "org.appspot.apprtc.LOOPBACK" true
+

+/**
+ * Simple CPU monitor. The caller creates a CpuMonitor object which can then
+ * be used via sampleCpuUtilization() to collect the percentual use of the
+ * cumulative CPU capacity for all CPUs running at their nominal frequency. 3
+ * values are generated: (1) getCpuCurrent() returns the use since the last
+ * sampleCpuUtilization(), (2) getCpuAvg3() returns the use since 3 prior
+ * calls, and (3) getCpuAvgAll() returns the use over all SAMPLE_SAVE_NUMBER
+ * calls.
+ *
+ * <p>CPUs in Android are often "offline", and while this of course means 0 Hz
+ * as current frequency, in this state we cannot even get their nominal
+ * frequency. We therefore tread carefully, and allow any CPU to be missing.
+ * Missing CPUs are assumed to have the same nominal frequency as any close
+ * lower-numbered CPU, but as soon as it is online, we'll get their proper
+ * frequency and remember it. (Since CPU 0 in practice always seem to be
+ * online, this unidirectional frequency inheritance should be no problem in
+ * practice.)
+ *
+ * <p>Caveats:
+ * o No provision made for zany "turbo" mode, common in the x86 world.
+ * o No provision made for ARM big.LITTLE; if CPU n can switch behind our
+ * back, we might get incorrect estimates.
+ * o This is not thread-safe. To call asynchronously, create different
+ * CpuMonitor objects.
+ *
+ * <p>If we can gather enough info to generate a sensible result,
+ * sampleCpuUtilization returns true. It is designed to never through an
+ * exception.
+ *
+ * <p>sampleCpuUtilization should not be called too often in its present form,
+ * since then deltas would be small and the percent values would fluctuate and
+ * be unreadable. If it is desirable to call it more often than say once per
+ * second, one would need to increase SAMPLE_SAVE_NUMBER and probably use
+ * Queue<Integer> to avoid copying overhead.
+ *
+ * <p>Known problems:
+ * 1. Nexus 7 devices running Kitkat have a kernel which often output an
+ * incorrect 'idle' field in /proc/stat. The value is close to twice the
+ * correct value, and then returns to back to correct reading. Both when
+ * jumping up and back down we might create faulty CPU load readings.
