Make bindings build on Windows again. (Not necessarily work, just build.)

Patch by: David James <james82@gmail.com>
(Tweaked by me.)

* subversion/bindings/swig/include/apr.swg:
  Define Perl typemaps for "long long" datatypes. Use apr_int64_t
  and apr_uint64_t to convert datatypes.
* subversion/bindings/swig/include/svn_types.swg
  (svn_filesize_t): Use APR_INT64_FMT_T instead of hardcoded
  long long format.
* subversion/bindings/swig/proxy/apr_h.swg: On 32-bit Windows,
  replace "__int64" with "long long" because SWIG no longer
  understands the former.
