* libmisc/limits.c: Avoid implicit conversion of pointers /
integers to booleans.
* libmisc/limits.c: Ignore the return value of umask(). We will
never return to the original umask.

sleep().
* libmisc/limits.c: Check the return value of nice() and
set_filesize_limit(), and report errors to syslog.

set_filesize_limit(). Change the prototype to return an int
instead of void.
