If we receive a signal from the command we executed, do not forward
...
it back to the command. This fixes a problem with BSD-derived
versions of the reboot command which send SIGTERM to all other
processes, including the sudo process. Sudo would then deliver
SIGTERM to reboot which would die before calling the reboot() system
call, effectively leaving the system in single user mode.

Refactor disable_execute() and my_execve() into exec_common.c for
...
use by sesh.c. This fixes NOEXEC when SELinux is used. Instead
of disabling exec in exec_setup(), disable it immediately before
executing the command. Adapted from a diff by Arno Schuring.

Redo utmp handling. If no getutent()/getutxent() is available,
...
assume a ttyslot-based utmp. If getttyent() is available, use
that directly instead of ttyslot() so we don't have to do the
stdin dup2 dance.

Add support for adding a utmp entry when allocating a new pty.
...
Requires the BSD login(3) or SYSV/POSIX getutent()/getutxent().
Currently only creates a new entry if the existing tty has
a utmp entry.

Use special values SIGCONT_FG and SIGCONT_BG instead of SIGUSR1 and

SIGUSR2 to indicate whether the child should be continued in the
foreground or background.

Instead of using a array to store received signals, open a pipe and
...
have the signal handler write the signal number to one end and
select() on the other end. This makes it possible to handle signals
similar to I/O without race conditions.
