Make Quickfix/J transport layer pluggable in order to replace MINA by other IO frameworks as Netty or Grizzly

Besides MINA there are some other Java IO frameworks as

• Netty
• Grizzly

In order to use them in the QF/J engine we need to create some API to make the IO framework pluggable.

Steps

• Replace current MINA transport by hard-wired Netty transport:
  • See project of lburgazzoli: https://github.com/lburgazzoli/lb-quickfixj
• Compare original code base with changed required to replace MINA by Netty:
  • In this way we could deduce some API requirements.
• Replace MINA by Grizzly and refine API.
• Also consider MINA 2.0 integration:
  • QFJ-664: Upgrade MINA from 1.1.8 to 2.0.4
