[svn-r29011] LFS changes in the autotools and library.

* We assume that fseeko and ftello exist.

* The *64 IO functions and types are no longer explicitly used.
  We now rely on a mapping provided by _FILE_OFFSET_BITS (or its
  equivalent).

* _LARGEFILE(64)_SOURCE is no longer exposed via AM_CPPFLAGS.

The CMake files have not yet been updated but CMake is still
functional. The CMake configure files will just run a few
unecessary tests and create unneeded #defines until they are
updated in a few days.

Tested on: Linux, OS X, Solaris, z/OS
