git-compat-util: add xstrdup_or_null helper
 
It's a common idiom to duplicate a string if it is non-NULL,
or pass a literal NULL through. This is already a one-liner
in C, but you do have to repeat the name of the string
twice. So if there's a function call, you must write:

  const char *x = some_fun(...);
  return x ? xstrdup(x) : NULL;

instead of (with this patch) just:

  return xstrdup_or_null(some_fun(...));
