This series create compression code on top of multifd. It is still WIP, but it is already: - faster that current compression code - it does the minimum amount of copies possible - we allow support for other compression codes - it pass the multifd test sent in my previous series
Test for existing code didn't work because code is too slow, I need to make downtime 10 times bigger to make it to converge on my test machine. This code works with same limits that multifd no- ToDo: - move printf's to traces - move code to a struct instead of if (zlib) inside the main threads. - improve error handling. Please, review and coment.
