Fixed javadocs all over. Improved input error
checking.
* java/nio/Buffer.java
(checkForUnderflow, checkForOverflow, checkIndex,
checkIfReadOnly, checkArraySize): New helper methods
for error checking.
* java/nio/ByteBufferHelper.java
(checkRemainingForRead, checkRemainingForWrite,
checkAvailableForRead, checkAvailableForWrite): Removed
no longer needed methods.
