Add support for min scheduling policy to node.
The binder driver has always supported setting a
min nice value for transactions. It looks like this
was always set to an out-of-range value (0x7f);
correct this to use a value of 0 by default (which
corresponds to nice 0).
Additionally, the new driver supports setting
a minimum scheduler *policy* as well, by reserving
2 bits for the scheduler policy in the flat_binder_object
structure. Add APIs to set this policy on a server object,
and set them properly when passing the object into
the driver.

Reduce libhwbinder API surface (1/?).
Removed in this round:
- All Vector'ed read/write methods
- Reading/writing dup native_handles
- Blob/ashmem support
- Special binder transactions (ping, dump, interface)
- Various unused helpers.
Obvious remaining items that require more work:
- writeString16()/writeCString() and read variants
- writeInterface() / enforceInterface()

Callback support for libhwbinder.
One of the prime differences between HIDL and Binder
is that HIDL allows the server implementation to do
a synchronous callback into the client with response
data. This callback allows the server to respond with
data that is anywhere - on the stack, the heap or globals -
without worrying about the lifetime of the data, since
it can immediately clean up (if necessary) when the callback
returns.
So we go from a chain like this:
IPCThreadState::executeCommand() // Execute BR_TRANSACTION
BBinder::transact()
ServerStub::onTransact()
Server::some_method()
// Do work, copy data, and return to ServerStub
// serialize data, and return to BBinder
// return to IPCThreadState
IPCThreadState::sendReply()
// done
to a chain like this:
IPCThreadState::executeCommand () // Execute BR_TRANSACTION
BBinder::transact ()
ServerStub::onTransact()
Server::some_method()
// Do work, send reply
ServerStub::TransactCallback(reply)
// Serialize data (until we get scatter-gather)
BBinder::TransactCallback(serialized_reply)
IPCThreadState::sendReply(serialized_reply)
// send reply over binder, return to BBinder
// return to ServerStub
// return to Server, server can clean up
// return to ServerStub
// return to BBinder
// return to IPCThreadState
// IPCThreadState cleanup
// done
To support this, the transact() and onTransact() methods
must support a callback argument, which is added here.
On the proxy side, this callback argument for transact()
can be ignored for now; after all, once the client side gets a
reply, the data is now in the reply Parcel, and the lifetime
of that Parcel is controlled by the Proxy itself. So it
can simply wait for transact() to return, at which point
the reply Parcel is filled.
In the existing Binder model, it would then deserialize
the reply Parcel into arguments that the client had passed
in, and then the Parcel will go out of scope and gets cleaned up.
In HIDL, we deseralize, call the *client* callback, and
then the Parcel goes out of scope and gets cleaned up.
This will change when we get scatter-gather support, but
this allows us to work with the callback-model before that.

Move hwbinder to the android::hidl namespace.
This should prevent clashes if projects do want
to link in both libbinder and libhwbinder.
Also had to pull in Static.h from
frameworks/native/include/private/binder, as that
was not part of the history we pulled from
frameworks/native.

Add new "shell command" feature to Binder objects.
IBinder has a new common interface for sending shell commands
to it. This can be implemented by system services to provide
a shell interface to the service, without needing to have separate
shell java code.
Also add a new "cmd" command line tool, which invokes the shell
command method on a system service. This is much like dumpsys,
but for shell commands.

Work around C11 const atomic restrictions.
Cast away the const qualifier in BBinder::findObject. C11, unlike C++11,
does not allow loads from const atomics. This is widely regarded as
a bug (see WG14 DR 459). This is a hack to work around it until it's
officially fixed in the spec.
load_const_atomic was adapted from commit
1e8587a479fd8b1ce9b594298a93f517816e8f15
I don't think we want to dignify this by putting it into a header file.

Remove incorrect android_atomic_...64 use.
Change the mExtras field in Binder.h to be a stdatomic.h atomic
value, and replace references to it with proper stdatomic.h calls.
This removes one of a small number of remaining 64 bit
android_atomic references. It also replaces the erroneously
non-atomic read accesses to mExtras.
It would be better if this used the C++11 <atomic> facility,
but we don't quite have that yet.

Binder: Make binder portable
Changes include
- Binder attempts to cast pointers to a int datatype
which is not sufficient on a 64-bit platform.
- This patch introduces new read/write functions into
Parcel that allow pointers to be written using the
uintptr_t datatype for compile-time data type size
selection.
- Change access specifier for the methods above.
- Binder uses the 64bit android_atomic_release_cas64
(aka cmpxchg)

Add callback hack to find out when to reload system properties.
Every IBinder object can accept a new transaction to tell it that
it might want to reload system properties, and in the process
anyone can register a callback to be executed when this happens.
Use this to reload the trace property.
This is very much ONLY for debugging.

some work to try to reduce the code size of some native libraries
- make sure that all binder Bn classes define a ctor and dtor in their respective library.
This avoids duplication of the ctor/dtor in libraries where these objects are instantiated.
This is also cleaner, should we want these ctor/dtor to do something one day.
- same change as above for some Bp classes and various other non-binder classes
- moved the definition of CHECK_INTERFACE() in IInterface.h instead of having it everywhere.
- improved the CHECK_INTERFACE() macro so it calls a single method in Parcel, instead of inlining its code everywhere
- IBinder::getInterfaceDescriptor() now returns a "const String16&" instead of String16, which saves calls to String16 and ~String16
- implemented a cache for BpBinder::getInterfaceDescriptor(), since this does an IPC. HOWEVER, this method never seems to be called.
The cache makes BpBinder bigger, so we need to figure out if we need this method at all.
