[PATCH v2 00/21]

Changes since v1:

 - fopen_or_warn() and warn_on_fopen_errors() are introduced. The
   latter's name is probably not great...
 - A new patch (first one) to convert a bunch to using xfopen()
 - Fix test failure on Windows, found by Johannes Sixt
 - Fix the memory leak in log.c, found by Jeff

There are still a couple of fopen() remained, but I'm getting slow again so let's get these in first and worry about the rest when somebody has time.
