Allocates a new pseudo-terminal.
You can later use fork() or the g_spawn_async() family of functions
to start a process on the PTY.
If using fork(), you MUST call vte_pty_child_setup() in the child.
If using g_spawn_async() and friends, you MUST either use
vte_pty_child_setup() directly as the child setup function, or call
vte_pty_child_setup() from your own child setup function supplied.
When using vte_terminal_fork_command_full() with a custom child setup
function, vte_pty_child_setup() will be called before the supplied
function; you must not call it again.
Also, you MUST pass the G_SPAWN_DO_NOT_REAP_CHILD flag.
If GNOME PTY Helper is available and
unless some of the VTE_PTY_NO_LASTLOG, VTE_PTY_NO_UTMP or
VTE_PTY_NO_WTMP flags are passed in flags, the
session is logged in the corresponding lastlog, utmp or wtmp
system files. When passing VTE_PTY_NO_HELPER in flags, the
GNOME PTY Helper is bypassed entirely.
When passing VTE_PTY_NO_FALLBACK in flags,
and opening a PTY using the PTY helper fails, there will
be no fallback to allocate a PTY using Unix98 PTY functions.
