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.

5273603e98 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.

Brad Fitzpatrick
837a0d0fb2 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().

This is (intendend to be) a no-op change.

At this stage, Binder RPCs just have an additional uint32 passed around

done with them yet.  That value should right now always be 0.

This now boots and seems to work.
