5b3d150932 Better signal handling. 
Instead of using a single variable to store the received signal, use
an array so we can't lose a signal when multiple are sent.
Fix process termination by SIGALRM in non-I/O logger mode.
Fix relaying terminal signals to the child in non-I/O logger mode.

a3f4278388 Fix a race between when we get the child pid in the parent and when 
the child process exits.  The problem exhibited as a hang after a
short-lived process, e.g. "sudo id" when no IO logger was enabled.

2634cf08cc Avoid installing signal handlers that are io-logger specific. Fixes 
job control when no io logger is enabled.

44341c9c15 Main sudo should not block signals; the plugin should do this in 
check_policy.

c3e87c2db3 Unlike most operating systems, HP-UX select() is not interrupted 
by SIGCHLD when the signal is registered with SA_RESTART.  If
we clear SA_RESTART when calling sigaction() for SIGCHLD we get
the expected behavior and the code in the select() loops already
handles EINTR correctly.

6b180d24da Fix the -s and -i flags and add support for the "implied_shell" 
option.  If the user does not specify a command, sudo will now pass
in the path to the user's shell and set impied_shell=true.  The
plugin can them either check the command normally or return -2 to
cause sudo to print a usage message and exit.

5be1b80169 Hard-code sudoers.so instead of using SUDOERS_PLUGIN since libtool 
appears to always install a shared object with the .so suffix.

b4f4afdf69 Pass in output function to lbuf_init() instead of writing to stdout. 
A side effect is that the usage info can now go to stderr as it should.
