Allow --enable-largefile and --disable-largefile configurations.

Configure process no longer needs nor checks size of curl_off_t.
Library will now be built with _REENTRANT symbol defined.

+- Introduce definition of _REENTRANT symbol in setup.h to improve library
+  usability.  Previously the configure process only used the AC_SYS_LARGEFILE
+  macro for debug builds, now it is also used for non-debug ones enabling the
+  use of configure options --enable-largefile and --disable-largefile which
+  might be needed for library compatibility.  Remove checking the size of
+  curl_off_t, it is no longer needed.

 - Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and
   the target host has only A records, it automatically falls back to an
