81c564798c runcmd: use a pipe for stdin to child processes 
this allows child processes to detect the exit of the parent by
looking for EOF on stdin

a9f5bfb3a5 util-runcmd: ignore spurious ECHILD errors 
when we get ECHILD in samba_runcmd it is because the parent has set
SIGCHLD to SIG_IGN. In that case the child status information is
lost. We then have to fallback on the logging of child error messages
for any useful information on what happened to the child.

A longer term fix is to stop using SIG_IGN for SIGCHLD in the standard
process model of s4.

b0b857d6ca s4-dns: use a loadparm list for samba_runcmd() commands 
This allows commands with multiple arguments and quoting to be used,
while still avoiding running a shell (and this having shell expansion
problems)

8756e13009 util: added samba_runcmd() 
This allows us to run a child command in an async fashion, with
control over logging of stdout and stderr (which appears in the Samba
log file). This is useful for ensuring we don't miss important
messages from rndc commands (for example).
