Add reachabilityFence, ReachabilitySensitive
Add the @ReachabilitySensitive annotation itself, and use it
in libcore itself, where needed.
Import OpenJDK9+181's reachabilityFence, so that it can be used in
preference to the annotation where it makes sense. Java 9's
stopgap reachabilityFence implementation doesn't work for us,
so replace it with a different stopgap.
The libcore changes correct many situations in which finalizers
could previously run prematurely according to the JLS. Or they
would correct them if we had a real implementation for
@ReachabilitySensitive.
The ZipFile constructor could close the file before notifying the
CloseGuard that it was open.
Aside from the ZipFile change, there should be no functional
change, yet.
Note that the ExemptionMechanism.java fix is the same as upstream.
Conspicuously missing:
- Any code, e.g. in ART or D8, that actually looks for the annotation.
- Uses in frameworks code, where it's probably most critical.

Set warnings for unbuffered I/O
The change introduces a new BlockGuard policy to track unbuffered
I/O. Policy can be set in the following way:
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectUnbufferedIO().build());
IoTracker generates warnings for unbuffered I/O if the operation
could be replaced with a buffered I/O.
The change also removes IoTrace class which was called each time an I/O
operation was invoked.

Remove FileDescriptor reference counting usage.
openJdk uses reference counting for closing FileDescriptor
instances. pre-openJdk code assumes that the creator
of FileDescriptor instance is responsible for its removal.
In pre-openJdk libcore, streams created by File(Input|
Output)Stream(FileDescriptor) will not close
received FileDescriptor.
This change reverts the code to the pre-openJdk behavior. We
found that there's code in framework (and possible some
third-party apps) that assumes pre-openJdk behavior.

Revert "Closing of filDes shared b/w multiple streams"
This reverts commit 5cbde77b3b5d11cb3125f4b8cd580cc1a2cba048.
The owner model may leak resources if the File is explicitly created
and passed to the FileOutputStream, then it will not have an owner and
won't be closed. Reverted to be replaced by reference counting.

Fix File(Input|Output)Stream blocking IO+close().
Switched to use IoBridge#read and #write instead
of OpenJdk implementation. Switched to use
IoBridge#closeAndSignalBlockedThreads instead of
OpenJdk #close0.
This change fixes some libcore.java.nio.channels.
FileIOInterruptTest tests that depend on blocking
IO operation being interrupted by #close call
in another thread. OpenJdk lacks this behavior, hence
switch to the IoBridge equivalents (this is significantly
easier than trying to reproduce IoBridge behavior
in OpenJdk methods).
