2020-09-14session: add unix socket api for app attachmentFlorin Coras1-0/+2
This is an af_unix socket alternative to the binary api. To enable it, add use-app-socket-api under session stanza in startup.conf. When the socket api is enabled, attachments through the binary api are disabled. The socket api only works with memfd fifo segments, i.e., shm segments are not supported.

Type:refactor Moves connect, disconnect, bind, unbind and app detach to message queue from binary api. Simplifies app/vcl interaction with the session layer since all session control messages are now handled over the mq. Add/del segment messages require internal C api changes which affect all builtin applications. They'll be moved in a different patch and might not be back portable to 19.08.
