e142428a9c Make Flattenable not virtual
Fallout from the Flattenable change, update all its uses.

Additionnaly, fix/tighten size checks when (un)flatten()ing
things.

Removed the assumption by some flattenables (e.g.: Fence)
that the size passed to them would be exact (it can
and will be larger in some cases)

The code in Parcel is a bit complicated so that we don't
have to expose the full implementation (and also to
keep the code smallish).

f5f8fa0bbd libbinder: include sys/uio.h instead of cutils/uio.h
libbinder is only built for the target, where bionic will provide
uio, so it does not need to include the libcutils wrapper around
uio for windows.

7f974ff2f3 Add a compatibility symbol for the MemoryBase constructor.
Third-party libraries are currently trying to use the
MemoryBase constructor but failing because we fixed the
definition of ssize_t. This is a stop-gap for users of
this private API until we can get them fixed.

e3e43b384e rename binder services main thread to Binder_*
When a binder service's main thread joins the thread pool
it retains its name (whatever the exec name was), which is
very confusing in systrace.

we now rename that thread just like its friends in the
thread pool.

8683fca395 improve [un]marshalling of non-binder objects
this change introduces a new class LightFlattenable<> which is
a protocol to flatten simple objects that don't require
binders or file descriptors; the benefit of this protocol is that
it doesn't require the objects to have a virtual table and give us
a consitant way of doing this.

we also introduce an implementation of this protocol for
POD structures, LightFlattenablePod<>.

Parcel has been update to handle this protocol automatically.

Sensor, Rect, Point and Region now use this new protocol.

555f89d8df 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.

7a7524810a get rid of MemoryHeapPmem
MemoryHeapPmem is not used any longer. PMEM is not a supported
type of memory by the system anymore. a particular device might
use PMEM and need something like MemoryHeapPmem, in this case this
should be implemented in device specific code (HAL).

This will most likely break older no longer supported targets.

a94f129a7b Some hardening of isolated processes by restricting access to services.
Services now must explicitly opt in to being accessed by isolated
processes.  Currently only the activity manager and surface flinger
allow this.  Activity manager is needed so that we can actually
bring up the process; SurfaceFlinger is needed to be able to get the
display information for creating the Configuration.  The SurfaceFlinger
should be safe because the app doesn't have access to the window
manager so can't actually get a surface to do anything with.

The activity manager now protects most of its entry points against
isolated processes.

3e2fb7056a Deprecate local-only CursorWindows.
There is no difference and has never really been a difference
between local-only and remotable CursorWindows.  By removing the
distinction officially in the API, we will make it easier to
implement CrossProcessCursor correctly.  CrossProcessCursor
is problematic currently because it's not clear whether a call
to getWindow() will return a local-only window or a remotable window.
As a result, the bulk cursor adaptor has special case handling
for AbstractWindowedCursors vs. ordinary CrossProcessCursors
so that it can set a remotable window before the cursor fills it.
All these problems go away if we just forget about local-only
windows being special in any way.

ec4e0063a1 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.

99b49840d3 PermissionCache caches permission checks
This is intended to absorb the cost of the IPC
to the permission controller.
Cached permission checks cost about 3us, while
full blown ones are two orders of magnitude slower.

CAVEAT: PermissionCache can only handle system
permissions safely for now, because the cache is
not purged upon global permission changes.

71f64dd876 Binder linkage no longer depends on JNI objrefs as persistent tokens
There are two areas that have changed to eliminate the assumption that
local jobject references are both canonical and persistent:

1. JavaBBinderHolder no longer holds onto and reuses it parent object
reference per se.  Since the underlying JavaBBinder object holds a
real global ref, this was redundant anyway.  Now, for purposes of its
transient need to perform JNI operations, it simply uses the current
jobject ref(s) passed during method invocation, and no longer attempts
to hold these refs beyond the scope of a single invocation.

2. Binder obituaries no longer assume that a jobject reference to a
recipient will always compare == as a 32-bit value with any future
reference to the same object.  The implementation now asks Dalvik
whether object references match.

This amended patch fixes the earlier bug around races between
remote binder death cleanup and local explicit unregistration of
VM-side death recipients.
