ShadowClassTable: preprocess data from ClassInfoLoader before calling newInstance().
ShadowClassTable: simplify the implementation of newInstance(), extract class creation into __createShadowClass().
ShadowObject: make getNetRef() package private.
ShadowObject: use get() on the JAVA_LANG_CLASS atomic reference.
ObjectShadowClass: use ASM Type instead of String with class signature.

NetReferenceHelper: make the method names conform to normal Java style.
ShadowClass, ShadowObject, ShadowClassTable, ShadowObjectTable: updated to reflect the changes.

ShadowString, ShadowThread: add constructors for un-initialized shadows.
StringInfoHandler, ThreadInfoHandler: let ShadowObjectTable handle the registration, keep only IO in the handler code.
ShadowObjectTable: drop the debug parameter from the register() method, use logging instead.
ShadowObjectTable: use special constructors when creating un-initialized shadows of special objects.
ShadowClassTable: avoid using the debug parameter when calling the register() static method.

MethodInfo: do all copying on demand.
MethodInfo: add getDescriptor() to provide full method type information.

FieldInfo: getType() renamed to getDescriptor(), as it really returns a String descriptor of the type.
MethodInfo: get*Type() or get*Types() renamed to get*Descriptor() or get*Descriptors() for the same reason as in case of FieldInfo.
ArrayShadowClass, ObjectShadowClass: updated to reflect the changes.

ShadowCommonClass: renamed to ObjectShadowClass
ShadowPrimitiveClass: renamed to PrimitiveShadowClass
ShadowClassTable: updated to reflect the changes

ShadowObject: add typed variant of setStateIfAbsent() method.
ShadowObject: implement setStateIfAbsent() using computeStateIfAbsent() and a trivial lambda.
ShadowObject: make getNetRef() method deprecated (it should never have been public).

CloseHandler: added try block around the invocation of the analysis atExit() method.

AnalysisHandler: collect arguments direction into an array to avoid repeated conversion from list to array.
AnalysisInvocation: modified to accept array of arguments instead of a list.
AnalysisInvocation: cosmetic cleanups.

ShadowClass, ShadowObject, ShadowString, ShadowThread: added formatting code to print out different shadow object.
ShadowObjectTable: added objects() method to provide an instance of Iterable <ShadowObject>.

ShadowString: use the ShadowObject implementation of hashcode() to go with the existing equals() implementation.

ShadowObject: use the whole object tag (a.k.a. net reference) instead of just object id to compare for equality.
ShadowObject: simplify the hash code calculation.

DiSLREServer: cleaned up error handling and reporting.
DiSLREServer: support for indicating server readiness and shutdown.
DiSLREServer: started migration to channel-based buffered I/O.

package into the top-level package, where it should be. Dependent classes updated
to reflect this move.

- Removed the old DiSL agent code as well as the old Java agent.
- Copied old shared DiSL agent headers to Shadow VM agent.
- Added JDK includes for JNI and JVMTI to avoid looking for them.
- Unified the naming of source directories.
- Updated the test infrastructure to the new build system layout.
- Examples can be now run even from the source distribution.
