New parser for length field based protocols

[EmadAlblueshi]

Signed-off-by: Emad Alblueshi [email protected]

Motivation:

A new LengthFieldParser that handles length field based protocols it uses the RecordParser internally with simple API it supports the following :

1. Length fields byte(1), short(2), medium(3), int(4) and long(8).
2. Maximum frame length the default is Integer.MAX_VALUE and can be changed explicitly.
3. Length field offset to skip explicit length while parsing.

It's rewritten instead of https://github.com/eclipse-vertx/vert.x/pull/3742 as @vietj and @tsegismont suggested in vertx-dev google group.

Thanks!

@tsegismont ping :-)

Hi @EmadAlblueshi , thanks for the updates. I was able to take another look today.

Can you update the very long test? I must admit I'm not prepared to review it. It seems many tests share the same code. Perhaps it can be factored out?

I will try my best to refactor it.

Hi @moxi-born @July-X Sorry for long time I was busy in my new job!

Hi @tsegismont as far as I remember you told me that the test code was so long and needs to be refactored. do you have any recommendations?

[tsegismont]

@EmadAlblueshi I'll come back to this after 4.4.2 is released
