APR patch: Win32 fixes

Two nits here.

    * apr_full_read would loop infinitely if the file was smaller than
      the buffer, because read_with_timeout wouldn't return APR_EOF.
    * apr_read wouldn't read because rv wasn't initialised.
      

        * apr/file_io/win32/readwrite.c (read_with_timeout):
        Successful ReadFile with 0 bytes read indicates end-of-file.
        (apr_read): Initialise `rv' before use.
