Ruslan Ermilov d15ff41778 - Added three new interfaces, NgAllocRecvMsg(), NgAllocRecvAsciiMsg(),
and NgAllocRecvData(), that dynamically allocate buffer for a binary
  message, an ascii message, and a data packet, respectively.  The size
  of the allocated buffer is equal to the socket's receive buffer size
  to guarantee that a message or a data packet is not truncated.

- Get rid of the static size buffer in NgSendAsciiMsg().
