Pedro F. Giffuni 547e0acbec patch: Bring in xstrdup and use it when appropriate.
The function savestr allows NULL return values during Plan A patching so in
case of out of memory conditions, Plan B can step in.  In many cases, NULL
value is not properly handled, so use xstrdup here (it's outside Plan A/B
patching, which means that even Plan B relies on successful operations).

Clean up some whitespaces while here
