2015-12-15erts: Allow enomem failures in port_SUITELukas Larsson
With the new forker implementation also enomem can be returned as an indicator that it is not possible to create more ports.

2015-12-15erts: Create forker process for spawn driverLukas Larsson
Instead of forking from the beam process, we create a separate process in which all forks are done. This has several advantages: 1) performance: * don't have to close all fd's in the world * fork only has to copy stuff from a small process * work is done in a completely seperate process * a 3x performance increase has been measured, can be made even greater (10x) if we cache the environment in child setup 2) stability * the exec is done in another process than beam, which means that if the file that we exec to is on an nfs that is not available right now we will not block a scheduler until the nfs returns. 3) simplicity * don't have to deal with SIGCHLD in the erts Unfortunately, this solution also implies some badness. 1) There will always be a seperate process running together with beam on unix. This could be confusing and undesirable. 2) We have to transfer the entire environment to child_setup for each command. OTP-13088
