Fix native allocation tracking on Dalvik.
Fixed issue where we had inverted logic when checking for
pending exceptions.
Changed the logic to not update the native allocation watermarks
after concurrent GC since the finalizers may not have been run at
this point.
Copied over the test from ART for ensuring that it is working.

Trim after explicit gc.
On Gingerbread, dvmHeapSourceTrim() is called 5 seconds
after every kind of GC. Current AOSP do trim only for
concurrent GC. That makes OOM killer too busy.
At least explicit GC need trim and in case of explicit
GC, there are no need to delay 5 seconds before trim.

Avoid deadlock.
dvmIsHeapAddress is the pointer validity checker for use outside the GC. If
it doesn't take the heap lock, it risks looking at data structures that are
changing under its feet. If it does take the heap lock, it risks deadlock
between a thread doing an explicit GC and the signal catcher trying to dump
threads (causing the GC thread to be suspended while holding the heap lock).
Calling back into managed code while holding the heap lock and with other
threads resumed sounds like an inherently bad idea to me, but that's a battle
for another day.
With this change, we can handle SIGQUIT while we're in ReferenceQueue.add
as a result of an explicit GC in a system doing concurrent collections, so
the only known problem is fixed.

Make interned strings non-movable.
At present objects referenced from dex files must have stable reference
values. With this change, only non-moving strings are interned. If a
user interns a movable string a non-moving copy is made and the copy is
added to the intern table.
As part of this change, the internal string hash code access routine will
update the hash code slot of a string object. In addition, StringObject
has been made a subclass of Object eliminating various down-casts that
would otherwise be explicitly required.

Use C++ linkage in GC headers and remove unneeded typedefs.
Some interfaces in Alloc.h had to be left with C linkage as they are
referenced by the interpreter assembler code. That dependency will be
addressed in a future commit.

Remove DVM_LOCK_INIT and DVM_LOCK_INITIAL_THIN_VALUE.
The original implementation for thin locks used a magic non-zero value
to encode the initial thin lock state. This magic value was kept
around in DVM_LOCK_INITIAL_THIN_VALUE and stored into the lock word of
newly allocated objects. A later revision to the thin locking code
made the initial thin lock value be 0. That change eliminated the
requirement that lock words be explicitly initialized as the allocator
always returns zero-filled memory.

Add a class flag CLASS_ISCLASS.
This flag is only turned on for the unique class Class, and it is
meant to make it possible to quickly test objects for "classiness" as
well as trivially figure out if one is looking at the class Class
itself.
Bonus: Made a few places that directly set class->accessFlags use
the prescribed macro for doing same.
