Fix a leak in Parcel::writeBlob.
Was mistakenly assuming that Parcel::writeFileDescriptor took
ownership of the fd that was passed in. It does not!
Added some comments and a default parameter to allow the caller
to specify whether it wishes the Parcel to take ownership.

Use ashmem for CursorWindows.
Bug: 5332296
The memory dealer introduces additional delays for reclaiming
the memory owned by CursorWindows because the Binder object must
be finalized. Using ashmem instead gives CursorWindow more
direct control over the lifetime of the shared memory region.
The provider now allocates the CursorWindows and returns them
to clients with a read-only protection bit set on the ashmem
region.
Improved the encapsulation of CursorWindow. Callers shouldn't
need to care about details like how string fields are allocated.
Removed the compile-time configuration of string and numeric
storage modes to remove some dead weight.

Rewrite battery history storage.
We now write battery history directly into a buffer, instead of
creating objects. This allows for more efficient storage; later
it can be even better because we can only write deltas.
The old code is still there temporarily for validation.

Fix for writing empty strings to Parcel::writeString8()
If writeString8 is called with the following sequence:
writeString8(String8(""));
writeString8(String8("TempString"));
Then in the readString8, the 2nd String i.e. "TempString" is not read,
instead an empty string is read.
The bug comes because of the write call for String8("") where there are
no String bytes present. In the write Statement, an extra ‘\0’ is
written. During the Marshalling, Following bytes are written:
1 2 3 4 5 ...
0x0 0x0 0xB ‘T’ ‘e’ ...
The readString8 function has a check that, if String length is 0, don’t
read anything. So the first byte is read as the length for the first
string. The second byte i.e. ‘\0’ is read as the length for the second
string and hence the second string becomes empty too.

Don't propagate StrictMode over one-way Binder calls.
This was causing stack stitching problems where a one-way call with
violations followed by a two-way call without violations was getting
the previous one-way call's violation stack stitched on to the second
caller's stack.
The solution is a little more indirect than I would've liked
(preserving the binder's onTransact flags until enforceInterface) but
was seemingly necessary to work without changing the AIDL compiler.
It should also be sufficiently cheap, since no new calls to
thread-local IPCThreadState lookups were required. The additional
work is just same-thread getter/setters on the existing
IPCThreadState.

StrictMode: gather and return violating stacks in Binder replies
Now, when Thread A has a strict mode policy in effect and does a
Binder call to Thread B (most likely in another process), the strict
mode policy is passed along, but with the GATHER penalty bit set which
overrides other policies and instead gathers all offending stack
traces to a threadlocal which are then written back in the Parcel's
reply header.

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
status:
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
reply.readExceptionCode().

Start of work on passing around StrictMode policy over Binder calls.
This is (intendend to be) a no-op change.
At this stage, Binder RPCs just have an additional uint32 passed around
in the header, right before the interface name. But nothing is actually
done with them yet. That value should right now always be 0.
This now boots and seems to work.

remove a dependency of GraphicBuffer (libui) on Parcel (libbinder).
Add a Flattenable interface to libutils which can be used to flatten
an object into bytestream + filedescriptor stream.
Parcel is modified to handle Flattenable. And GraphicBuffer implements
Flattenable.
Except for the overlay classes libui is now independent of libbinder.

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.
