shared: add PTY helper
This Pty API wraps the ugliness that is POSIX PTY. It takes care of: - edge-triggered HUP handling (avoid heavy CPU-usage on vhangup) - HUP vs. input-queue draining (handle HUP _after_ draining the whole input queue) - SIGCHLD vs. HUP (HUP is no reliable way to catch PTY deaths, always use SIGCHLD. Otherwise, vhangup() and friends will break.) - Output queue buffering (async EPOLLOUT handling) - synchronous setup (via Barrier API) At the same time, the PTY API does not execve(). It simply fork()s and leaves everything else to the caller. Usually, they execve() but we support other setups, too. This will be needed by multiple UI binaries (systemd-console, systemd-er, ...) so it's placed in src/shared/. It's not strictly related to libsystemd-terminal, so it's not included there.
