Fix the jweak implementation.
We need to distinguish between "cleared weak global" and "deleted weak global".
Previously we used NULL for both. Now we add a magic value for cleared weak
globals. I've also switched the GC over to using iterators, so IndirectRefTable
itself becomes responsible for not showing bad pointers to the GC.
I've also improved the reference table dumping to cope with the new scheme and
to be a bit easier to read (through extra indentation).

Fix native method logging to show local references rather than direct pointers.
This is necessary (but not sufficient) for debugging third-party JNI bugs.
It's the second half of the logging story, but still doesn't address the
question of "how does the developer turn on the logging?".
This removes the variant JNI bridges at the cost of adding a couple of
booleans to struct Method. Performance is about the same, except synchronized
native methods are quite a bit faster after the change.
Before:
benchmark ns linear runtime
_emptyJniMethod0 333 ==========
_emptyJniMethod6 367 ===========
_emptyJniMethod6L 921 ==============================
_emptyJniStaticMethod0 259 ========
_emptyJniStaticMethod6 287 =========
_emptyJniStaticMethod6L 873 ============================
_emptyJniStaticSynchronizedMethod0 404 =============

_emptyJniStaticMethod6 293 =========
_emptyJniStaticMethod6L 968 =============================
_emptyJniStaticSynchronizedMethod0 265 ========
_emptyJniSynchronizedMethod0 323 ==========
A better optimization for the case where there are reference arguments
would be to keep a list of argument indexes in the struct Method, so we
could iterate directly over those arguments that need converting to
local references. That would also let us do something about the overhead
of repeatedly looking up which local reference table and cookie to use.
But now is not the time.

Improve JNI tracing even further.
This adds return values and general support for the primitive types.

JNI: libcore.io.Posix.writeBytes -> GetIntField((JNIEnv*)0x9ebf9a8, 0x3e00005, java.io.FileDescriptor.descriptor)
JNI: <- GetIntField returned 13
Although we still decode jclass, when a jclass is a return value we also
include the pointer. This makes it easier to follow call sequences like
this:
JNI: dalvik.system.NativeStart.main -> FindClass((JNIEnv*)0x9e3e458, "java/text/Bidi$Run")
JNI: <- FindClass returned java.lang.Class<java.text.Bidi$Run> (0x100001)
JNI: dalvik.system.NativeStart.main -> NewGlobalRef((JNIEnv*)0x9e3e458, 0x100001)
JNI: <- NewGlobalRef returned 0x100002
Here, the argument to NewGlobalRef is clearly the jclass local reference.

Improve -verbose:jni.
The old output just told you what functions were being called and made no
attempt to show you their arguments. The new output was sufficient to debug
an actual problem with an app we don't have the source to.
Still to do:
0. an easier way for third-party developers to enable this.
1. the primitive type arguments to SetIntField and so forth.
2. return values.
A few examples of the new output...
A decoded jclass:
JNI: libcore.io.Posix.readBytes called IsInstanceOf((JNIEnv*)0x9618470, 0x28100015, java.lang.Class<byte[]>)
A decoded jfieldID:
JNI: libcore.io.Posix.ioctlInt called GetIntField((JNIEnv*)0x9618470, 0x5cb00011, java.io.FileDescriptor.descriptor)
A decoded jmethodID (the FileDescriptor constructor):
JNI: libcore.io.Posix.open called NewObject((JNIEnv*)0x9780480, java.lang.Class<java.io.FileDescriptor>, java.io.FileDescriptor.<init>()V, ...)
A const char*:
JNI: libcore.io.Posix.getsockoptLinger called NewStringUTF((JNIEnv*)0x9618470, "getsockopt")
A jint release mode:
JNI: libcore.io.Posix.writeBytes called ReleaseByteArrayElements((JNIEnv*)0x9780480, 0x2700009, (void*) 0xf5f623c4, JNI_ABORT)
The -verbose:jni option now turns on a bit more output about JNI_OnLoad calls
but no longer causes any logging of calls to JNIEnv or JavaVM functions. The
old -Xjnitrace: option has been extended to enable this new tracing for the
native methods that it covers. They go very well together for debugging
purposes.
I've also made us a bit more verbose if we fail to initialize. In the longer
term I think we want to just abort if we hit any failure during startup, but
my extra logging will save us a bit of time next time we have one of these
failures (this one was caused for me by only having one half of the finalizer
watchdog change; I was missing the libcore side).

Previously, clearing the growth limit only updated the maximumSize of

beyond the original heap size. With this change the limit is always
kept in agreement with the maximumSize.

Dx defaults to emitting dexfiles without jumbo opcodes.
There's compatibility issues with going back and forth between versions,
and it's best to have dx default to a stable point and allow
optimizations to be controlled by switches. For jumbo opcodes to be
enabled, dx can be given the switch "--target-api=14".

Do not initiate a concurrent collection if one is already running.
It is possible to cause a recursive garbage collection by writing a
program that triggers a concurrent garbage collection and initiates a
concurrent garbage collection before the garbage collection thread is
scheduled. For example
for (;;) { new byte[16 << 20]; System.gc(); }
When this condition occurs a warning is logged although such warnings
ought to be upgraded to fatal errors. With this change, when the
garbage collection thread is scheduled it first checks to see if there
is a running collection before calling down to start the collection.

Fix an issue regarding FindClass and threads without native methods.
Chapter 4 of the JNI specification states that when FindClass is called
through the Invocation Interface and there is no associated method, the
result of ClassLoader.getBaseClassLoader() is used as the class loader.
Previously, the case where FindClass is called from a main thread was
special cased to ensure this behavior. However, threads which attach to
the VM but are not the main thread require similar treatment. With this
change those threads are similarly treated as a special case.

Fix two issues with the card table.
Several tricks are used to adjust the base of the card table to save
instructions in the write barrier. This change corrects two
situtations where the card table did not properly account for the
effects of these tricks.
First, the card table is over allocated to ensure that the start
address can be magically aligned. When releasing the allocation these
additional bytes were not supplied to munmap creating a potential
leak.
Second, the valid card check did not use the right base address for a
containment check. The check used the allocation base which is may be
lower than the actual starting address. This would cause valid cards
at the high end of the heap to be considered invalid and invalid cards
at the low end of the heap to be considered valid.

Update dex file magic number.
Even though the dex format was technically resilient with respect to
the addition of new opcodes, consensus is that the errors one sees
when trying to use a new dex file on an old build were sufficiently
inscrutable that it was worth the effort to update the version number
embedded in the dex format magic.
This change updates dx to produce the new version number when extended
opcodes are enabled (which is the default, but may be overridden by
targeting an older API level).
This also updates the vm to recognize and accept both the new current
version number as well as the immediately previous one. Note: It won't
reject an old-version file if it happens to use the new opcodes; that
would just be a gratuitous and pointless failure.
