16aa5c3d59 improve IOException message in the case of a Runtime.exec() failure 
We now properly forward the errno value from the child when execvp()
fails, which the parent then uses to for the errno message as well as
including the failed command's name in the message.

c3824c6844 fix crash when encountering invokespecial call to abstract method 
We must throw an AbstractMethodError when such a call is executed (not
when the call is compiled), so we compile this case as a call to a
thunk which throws such an error.

16a8777fd2 override getResource(s) in SystemClassLoader 
OpenJDK's java.lang.ClassLoader.getResource makes use of
sun.misc.Launcher to load bootstrap resources, which is not
appropriate for the Avian build, so we override it to ensure we get
the behavior we want.

c743140e08 add new subroutine test 
This test covers the case where a local stack slot is first used to
store an object reference and later to store a subroutine return
address.  Unfortunately, this confuses the VM's stack mapping code;
I'll be working on a fix for that next.

The new test requires generating bytecode from scratch, since there's
no reliable way to get javac to generate the code we want.  Since we
already had primitive bytecode construction code in Proxy.java, I
factored it out so we can reuse it in Subroutine.java.

3d49173b0b avoid inifinite recursion if java.lang.Object is missing; refactoring 
When trying to create an array class, we try to resolve
java.lang.Object so we can use its vtable in the array class.
However, if Object is missing, we'll try to create and throw a
ClassNotFoundException, which requires creating an array to store the
stack trace, which requires creating an array class, which requires
resolving Object, etc..  This commit short-circuits this process by
telling resolveClass not to create and throw an exception if it can't
find Object.

While doing the above work, I noticed that the implementations of
Classpath::makeThrowable in classpath-avian.cpp and
classpath-openjdk.cpp were identical, so I made makeThrowable a
top-level function.

Finally, I discovered that Thread.setDaemon can only be called before
the target thread has been started, which allowed me to simplify the
code to track daemon threads in the VM.

459f4d5194 fix openjdk-src bootimage build 
The main change here is to use a lazily-populated vector to associate
runtime data with classes instead of referencing them directly from
the class which requires updating immutable references in the heap
image.  The other changes employ other strategies to avoid trying to
update immutable references.

3d18f88ad9 fix Runtime.exec bugs 
The first bug affected POSIX systems: if the app never called
Process.waitFor, we'd never call waitpid on the child and thus leak a
zombie process.  This patch ensures that we always call waitpid by
spawning a thread to handle it.

The second bug affected Windows systems: we weren't closing the
child's ends of the stdin, stdout, and stderr pipes after process
creation, which lead to us blocking forever while reading from the
child's stdout or stderr.

c1c9d2111b remove GNU Classpath and Apache Harmony compatibility code 
Rather than try to support mixing Avian's core classes with those of
an external class library -- which necessitates adding a lot of stub
methods which throw UnsupportedOperationExceptions, among other
comprimises -- we're looking to support such external class libraries
in their unmodified forms.  The latter strategy has already proven
successful with OpenJDK's class library.  Thus, this commit removes
the stub methods, etc., which not only cleans up the code but avoids
misleading application developers as to what classes and methods
Avian's built-in class library supports.

d0d53e2e10 fix custom-classloader-related concurrency problems and other bugs 
The main changes in this commit ensure that we don't hold the global
class lock when doing class resolution using application-defined
classloaders.  Such classloaders may do their own locking (in fact,
it's almost certain), making deadlock likely when mixed with VM-level
locking in various orders.

Other changes include a fix to avoid overflow when waiting for
extremely long intervals and a GC root stack mapping bug.

d819a75f36 more work towards OpenJDK classpath support 
The biggest change in this commit is to split the system classloader
into two: one for boot classes (e.g. java.lang.*) and another for
application classes.  This is necessary to make OpenJDK's security
checks happy.

The rest of the changes include bugfixes and additional JVM method
implementations in classpath-openjdk.cpp.

cddea7187d preliminary support for using OpenJDK's class library 
Whereas the GNU Classpath port used the strategy of patching Classpath
with core classes from Avian so as to minimize changes to the VM, this
port uses the opposite strategy: abstract and isolate
classpath-specific features in the VM similar to how we abstract away
platform-specific features in system.h.  This allows us to use an
unmodified copy of OpenJDK's class library, including its core classes
and augmented by a few VM-specific classes in the "avian" package.

17c1a552d5 break each Class, Field, and Method into separate classes 
In order to facilitate making the VM compatible with multiple class
libraries, it's useful to separate the VM-specific representation of
these classes from the library implementations.  This commit
introduces VMClass, VMField, and VMMethod for that purpose.
