    What was done as part of this:
    
    - The native layer is now a simplified native implementation. In theory much easier to
implement.
    - The native layer won't call any mallocs for io_submit though, get_iocb is a function
that will have a cirtcular cache of objects that will be reused on writes. we used to malloc
before every write submit
    
    - I have moved stuff around to make it easier to understand (for instance separated packages
for nio and aio under the journal)
    
    - merged AIOCallback and a useless class IOSubmit into a single IOCallback
    
    - added a test on create to sync test performance
    
    - The callbacks are also reused now through a circular log
    
    
    Everything else stayed the same, the whole testsuite is passing and I have executed extensive
tests on this (through manual testing)
