/*
* Run a command while logging its stdout and stderr
*
* WARNING: while this function is running it will clear all SIGCHLD handlers
* if you rely on SIGCHLD in the caller there is a chance zombies will be
* created if you're not calling waitpid after calling this. This function will
* log a warning when it clears SIGCHLD for processes other than the child it
* created.
*
* Arguments:
* argc: the number of elements in argv
* argv: an array of strings containing the command to be executed and its
* arguments as separate strings. argv does not need to be
* NULL-terminated
* status: the equivalent child status as populated by wait(status). This
* value is only valid when logwrap successfully completes. If NULL
* the return value of the child will be the function's return value.
* ignore_int_quit: set to true if you want to completely ignore SIGINT and
* SIGQUIT while logwrap is running. This may force the end-user to
* send a signal twice to signal the caller (once for the child, and
* once for the caller)
* logwrap: when true, log messages from the child
*
* Return value:
* 0 when logwrap successfully run the child process and captured its status
* -1 when an internal error occurred
* -ECHILD if status is NULL and the child didn't exit properly
* the return value of the child if it exited properly and status is NULL
*
