The thread pool is a working server, made of a set of worker threads that can be mapped on CPU cores.
Each worker loop on pick from the same input queue jobs to do.
When a job is done, the worker sends a return if a return is defined.
A selective abort allows to cancel parallel jobs (usage: a client pushed jobs, but from a response of one job, the other linked jobs becomes useless).

# jobs
A job is a message (notifiedFIFO_elt_t):
next: internal FIFO chain, do not set it
key: a long int that the client can use to identify a message or a group of messages
responseFifo: if the client defines a response FIFO, the message will be posted back after processing
processingFunc: any funtion (type void processingFunc(void *)) that the worker will launch
msgData: the data passed to processingFunc. It can be added automatically, or you can set it to a buffer you are managing
malloced: a boolean that enable internal free in these cases: no return Fifo or Abort feature
The job messages can be created with newNotifiedFIFO_elt() and delNotifiedFIFO_elt() or managed by the client.
