SystemProperties.get() is not particularly fast,
especially if a string is returned. Since ro.* values
are unable to be changed, there's no need to
continously re-query them. Cache the value at
static init time to trivially fix this.
Test: refactoring CL.

This patch adds first validation information to:
- ValidationProbeEvent, by extending the probe_type int field of to
also include a bit indicating if the probe was part of a first
validation attempt or not.
- NetworkMonitorEvent, by defining new contants for the event_type
field.
Test: $ runtest frameworks-net
+ manually generating events and inspecting the
output of $ adb shell dumpsys connmetrics list

This is a continuation of b/26545374, since now we can also set the
metered bit with NetworkScorer. The tracking of metered state changes
will be implemented in a seperate CL.

Properly account for VPN apps that make heavy use of the tun
interface. Prior to this change a VPN app could be incorrectly charged
for more data than it actually used if it sent more traffic through
the tun interface than the underlying interface.
This change excludes VPN app traffic on the tun interface from the
adjustment pool and doesn't redistribute traffic to the VPN app.
Instead all of the redistributed traffic is deducted from the VPN app
which effectively represents any overhead incurred by the VPN app.

Change-Id: I06f01aa8fe5fdc06b2d36cfb9c68feb244c2e5de
This patch changes the way that the ConnectivityThread is lazily
instantiated by using the "lazy initialization holder class idiom".
The first code point that tries to obtain a reference to the unique
ConnectivityThread instance will trigger the creation of the Singleton
class, which will guarantee a thread-safe initialization of the static
INSTANCE field inside Singleton according to the language specs.
This is the Item #71 of Effective Java.
The unique static instance of ConnectivityThread is not stored directly
inside ConnectivityThread class but is stored in a static nested class.
This is to avoid triggering the creation of that unique instance when
Zygote does class preloading at phone startup. Otherwise this would lead
to Zygote creating a new OS thread during preloading, which is a fatal
error.
Test: frameworks-wifi tests pass

This patch removes the static singleton looper used by
ConnectivityManager and instead uses the common ConnectivityThread.
This allows to removes the static atomic counter used to track
the number of registered NetworkCallback in ConnectivityManager, because
the looper is not turned off anymore when no callbacks are registered.
Also an overloaded version of sendRequestForNetwork is added taking as a
new parameter a Handler. This will allow to overload various callback
and request related API calls with user provided Handlers.

Change-Id: If956addbf8e7b11b36a4b966de7fca00e8f362c1
This patch simplifies CallbackHandler in the following way:
- CallbackHandler directly uses the static references to
sNetworkCallback and sCallbackRefCount. This allows to remove
instance fields in CallbackHandler.
- CallbackHandler does not have a reference to ConnectivityManager
anymore
- CallbackHandler.getObject() is now generic in a type-safe way.

and gives a more readable error message.

Add option '--streaming' to 'am start' and 'am profile' commands.
If the option is given, the output of method trace profiling
will be streamed into the specified file, so the output is no
longer limited by the buffer size.
Test: m -j48 test-art-host;
m -j48 ART_TEST_TRACE=true ART_TEST_TRACE_STREAM=true test-art-host;
I also tested manually. Tried all 8 combinations of
sampling/instrumention
streaming/non-streaming
'am start --start-profiler' / 'am profile start'
The output files are all in expected shape.
