Bug #11761530: 54035: MSYQLD_SAFE BEHAVIOUR CONSUMES TOO MUCH CPU IF IT IS UNABLE TO RESTART MY

Added a trottling mechanism to mysqld_safe.
On every 5 sub-second restarts it will wait for a second before attempting again.
Note that this requires 'sleep' and 'date' command line utilities.
The code would adjust and will do nothing if any of them is not present.
