  new function fopen_stat() and open_stat(),
  add new param for file_exists_p().
* src/init.h: Add param file_stats_t to run_wgetrc().
* src/ftp.c: Amend calls to extended functions.
* src/hsts.c: Likewise.
* src/http.c: Likewise.

Added fopen_stat() and open_stat() that checks to makes sure the file didn't
change underneath us.
Return error from file_exists_p().
Added a way to return error from this file without major surgery to the
callers.
