Update to version 5.1.2.  Patches removed above are no longer needed,

December 2006: t1lib-5.1.1:
---------------------------
- DESTDIR support was missing and has been addded in install-target i
  for type1afm.
- A bug fix in Anti-Aliasing subsampling code, which could make t1lib crash
  under certain conditions.
- Small number of further fixes, in particular with respect to the build
  mechanism.

December 2007: t1lib-5.1.2:
---------------------------
- Small number of fixes reported by users. The fixes pertain to a
