Given the following Java:

class Test2Class {
  static void test(Object a, Object b) {
    assert(a == b);
  }
}

When running jbmc with the core models: jbmc Test2Class.class --function Test2Class.test --classpath ../../../src/java_bytecode/library/core-models.jar:.

The following error is generated:

struct: component type does not match: signedbv
  * width: 32
  * #c_type: signed_int vs. 
terminate called after throwing an instance of 'int'
Aborted (core dumped)

The component that is specifically the wrong type is monitorCount from java.lang.Object model.

The 'monitorCount' field is a counter in the 'java.lang.Object' model
(part of the java core models library). This field is used to
implement a critical section and is thus necessary to support
concurrency.

This commit makes sure that this field (if present) is always zero
initialized as it is not meant to be non-deterministic.

This field is present only if the java core models library is loaded.

'@lock' field (fixes diffblue#2307)

The 'cproverMonitorCount' field is a counter in the 'java.lang.Object'
model (part of the java core models library). This field is used to
implement a critical section and is thus necessary to support
concurrency.

This commit makes sure that this field (if present) is always zero
initialized as it is not meant to be non-deterministic.

This field is present only if the java core models library is loaded.

Additionally, the commit removes '@lock' field from root class
(usually: 'java.lang.Object') as it has been superseded by a locking
mechanism implemented in the java core models library.

Modified relevant unit/regression tests to reflect this change.
