837a0d0fb2c3fba8082d47d04cb6120af1eb9a54 14-Jul-2010 Brad Fitzpatrick <bradfitz@android.com> Add Parcel::readExceptionCode() and Parcel::writeNoException()

Add native Parcel methods analogous to the Java versions.

Currently, these don't do much, but upcoming StrictMode work changes
the RPC calling conventions in some cases, so it's important that
everybody uses these consistently, rather than having a lot of code
trying to parse RPC responses out of Parcels themselves.

As a summary, the current convention that Java Binder services use is
to prepend the reply Parcel with an int32 signaling the exception

0: no exception
-1: Security exception
-2: Bad Parcelable
-3: ...
-4: ...
-5: ...

... followed by Parceled String if the exception code is non-zero.

With an upcoming change, it'll be the case that a response Parcel can,
non-exceptionally return rich data in the header, and also return data
to the caller. The important thing to note in this new case is that
the first int32 in the reply parcel *will not be zero*, so anybody
manually checking for it with reply.readInt32() will get false
negative failures.

Short summary: If you're calling into a Java service and manually
checking the exception status with reply.readInt32(), change it to

83c0446f27b9542d6c2e724817b2b2d8d1f55085 23-May-2009 Mathias Agopian <mathias@google.com> 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.
