More fixes prompted by gcc's warn_unused_result, in the tools directory.

Note that some of the existing error checking for asprintf was wrong for Linux. 
 asprintf in glibc returns -1 on error, but leaves the pointer uninitialized.  
Only the BSDs zero out the pointer on error.

Also, while fixing these warnings I saw several error paths that were 
incorrect.  This patch minimally fixes the warn_unused_result; more complete 
error path cleanup will be a later patch.


Please apply to xen-unstable.
