fix: stop using "magic" numbers in string operations for the copyannofile2log feature fix: When using the copylogfromannofile workaround, extract the build ID and build duration and add to the log as these are useful for analysis. The log should now be identical to the stdout file. fix: Remove extra blank lines from output in copylogfromannofile mode.

/* 
   ransleep.c: sleep for some time period specified in milliseconds
               optionally choose a random time up to the maximum time specified.

   Description: Useful for delays between retries and for perturbing the
	        start times of tools which might cause resource starvation 
		if they all execute at exactly the same time.
