Siddhesh Poyarekar 27b6edbb09 support: Also return fd when it is 0 
The fd validity check in open_dev_null checks if fd > 0, which would
lead to a leaked fd if it is == 0.

Adhemerval Zanella e814f4b04e support: Add support_open_dev_null_range 
It returns a range of file descriptor referring to the '/dev/null'
pathname.  The function takes care of restarting the open range
if a file descriptor is found within the specified range and
also increases RLIMIT_NOFILE if required.

Checked on x86_64-linux-gnu.
