Description

We should implement a new routine in libc to spawn a process, and connect its standard input or output to a file descriptor in the parent process. popen(3c) will be implemented in terms of the new function:

int posix_spawn_pipe_np(pid_t *pidp, int *fdp,
     const char *cmd, boolean_t write,
     posix_spawn_file_actions_t *fact, posix_spawnattr_t *attr);

Other consumers can get similar behavior to popen(3c), but with control over posix_spawn_file_actions_t and posix_spawnattr_t, and without the overhead of popen()'s list of FILE's.
