Serge Hallyn 2b22a6909d libsubid: don't print error messages on stderr by default 
Closes #325

Add a new subid_init() function which can be used to specify the
stream on which error messages should be printed.  (If you want to
get fancy you can redirect that to memory :)  If subid_init() is
not called, use stderr.  If NULL is passed, then /dev/null will
be used.

This patch also fixes up the 'Prog', which previously had to be
defined by any program linking against libsubid.  Now, by default
in libsubid it will show (subid).  Once subid_init() is called,
it will use the first variable passed to subid_init().

Thomas Abraham 82fa6eccf9 lib/spawn.c run_command: don't loop forever if waitpid() is returning ECHILD 
If SIGCHILD is being ignored, waitpid() will forever error with ECHILD and
this loop with never end, so don't loop if it errors with ECHILD.

nekral-guest f870cc7eab Miscellaneous: 
* lib/prototypes, libmisc/basename.c (Basename): Input is a
	constant string.
	* lib/prototypes.h, lib/spawn.h, lib/spawn.c, src/userdel.c,
	lib/nscd.c, lib/Makefile.am: Delete spawn.h. Move from spawn.h to
	prototypes.h.
	* src/userdel.c: Remove unused variables.
	* lib/nscd.c: Remove unused header files.
	* lib/nscd.c: Add the program name to error messages.
	* lib/nscd.c: Indicate when nscd does not terminate normally (signal).
	* lib/spawn.c: Updated header.
	* lib/spawn.c: Flush stdout and stderr to avoid inheriting from
	ongoing buffers.
	* lib/spawn.c: Avoid implicit conversion of pointer to boolean.
	* lib/spawn.c: Replace perror by a complete message.
	* lib/spawn.c: Continue to wait for the child if another child
	terminates.

nekral-guest fc0057ff35 2011-08-20 Jonathan Nieder <jrnieder@gmail.com> 
* lib/Makefile.am: Added lib/spawn.c and lib/spawn.h.
	* lib/nscd.c, lib/spawn.c, lib/spawn.h: It is not possible to
	differentiate between an nscd failure, and a failure to execute
	due to no nscd with posix_spawn. Use our own run_command routine.
	* src/userdel.c: Use run_command()
