  Log:
  Fix, and simplify, the getting/setting of errno in Foreign.C.Error.
  
  It was previously wrong: although we called a C function to get the
  location of errno (correct), we cached the result in a CAF which was
  wrong because the location is OS thread dependent.  We must call the C
  function every time we need the value of errno.
  
  I also simplified things by making the getter/setter functions inlined
  in the same way as the other C fragments in this library, and putting
  them in HsBase.h.
