dcf6602daa Use a socketpair to pass signals from parent to child. Child will 
now pass command status change info back via the socketpair.  This
allows the parent to distinguish between signals it has been sent
directly and signals the command has received.  It also means the
parent can once again print the signal notifications to the tty so
all writes to the pty master occur in the parent.  The command is
now always started in background mode with tty signals handled
by the parent.

871b3fb125 Fix a few typos in the descriptions; from Jeff Makey 
Only do the check for krb5_get_init_creds_opt_free() taking two
arguments if we find krb5_get_init_creds_opt_alloc().  Otherwise
we will get a false positive when using our own
krb5_get_init_creds_opt_free which takes only a single argument.

febc3cbb1f Need to ignore SIGTT{IN,OU} in child when running the command in the 
background.  Also some minor cleanup.

78cd63e074 Instead of calling sigsuspend when waiting for SIGUSR[12] from parent, 
install the signal handlers w/o SA_RESTART and let them interrupt waitpid().

e62dd7645f Defer setting terminal into raw mode until just before we fork() 
and only do it if sudo is the foreground process.
If we get SIGTT{IN,OU} and sudo is already in the foreground be sure
to set raw mode before continuing the child.

c77ef16fcd Fix handling of SIGTTOU/SIGTTIN in program being run. We now only

foreground process.

425026fa11 Do I/O in parent instead of child since the parent can have both 
/dev/tty as well as the pty fds open.  The child just sets things
up and waits for its grandchild and writes the signal description
to the pty master if the command was killed by a signal.

1a5afcbb15 Make transcript mode work as long as we can figure out our tty, even if 
it is not stdin.  We'd like to use /dev/tty but that won't be valid after
the setsid().

0d04ffc40c Associate the grandchild's pgrp with the tty instead of the child's 
and just get suspend notifications via SIGCHLD instead of directly.
This fixes a hang with programs that try to set terminal attributes
and is more consistent with how the shell handles things.

88b93973fe Run command in its own pgrp (like the shell does) for easier signalling. 
No need to relay SIGINT or SIGQUIT to parent, just send to grandchild.
Don't want grandchild stopped events in the child (only termination).
Flush output after suspending grandchild before signalling parent.

f44c2261fd Don't set stdout to blocking mode when flushing remaining output. It
