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:

- // IMPORTANT NOTE:
- // In case of the older 3.0 UNDI, if the input buffer address is beyond 4GB,
- // DO NOT call the map function on the given buffer, instead use
- // a global buffer. The reason is that UNDI3.0 has some unnecessary check of
- // making sure that all the addresses (whether or not they will be given
- // to the NIC ) supplied to it are below 4GB. It may or may not use
- // the mapped address after all (like in case of CPB and DB)!
- // Instead of using the global buffer whose address is allocated within the
- // 2GB limit if I start mapping the given buffer we lose the data, here is
- // why!!!
- // if our address is > 4GB, the map call creates another buffer below 2GB and
- // copies data to/from the original buffer to the mapped buffer either at
- // map time or unmap time depending on the map direction.
- // UNDI will not complain since we already mapped the buffer to be
- // within the 2GB limit but will not use (I know undi) the mapped address
- // since it does not give the user buffers to the NIC's receive unit,
- // It just copies the received packet into the user buffer using the virtual
- // (CPU) address rather than the mapped (device or physical) address.
- // When the UNDI call returns, if we then unmap the buffer, we will lose
- // the contents because unmap copies the contents of the mapped buffer into
- // the original buffer (since the direction is FROM_DEVICE) !!!
- //
- // this is not a problem in Undi 3.1 because this undi uses it's map callback
- // routine to map a cpu address to device address and it does it only if
- // it is giving the address to the device and unmaps it before using the cpu
- // address!
