Retiring the ANT/JAVA build and removing the older EDK II packages that required ANT/JAVA.
Last Ant/Java build was r7166
Developers requiring the Java/Ant packages should checkout the branch from:

-; This function is called to execute an EBC CALLEX instruction

-; code. For IA32, we simply switch stacks and jump to the
-; specified function. On return, we restore the stack pointer
-; to its original location.
-;
-; Destroys no working registers.

-; Routine Description:
-; When EBC calls native, on return the VM has to stuff the return

-; in the register, so simply return and the caller should get the
-; return result properly.
-;
-; Arguments:
