* fhandler_disk_file.cc (fhandler_disk_file::readdir_helper): Simplify
code which checks for symlinks. Fix problem with UNC paths.
* environ.cc (struct parse_thing): Remove transparent_exe option.
* syscalls.cc (transparent_exe): Remove.
(unlink): Always add stat_suffixes, drop transparent_exe check.
(open): Ditto.
(link): Ditto.
(pathconf): Ditto.
* fhandler_disk_file.cc (fhandler_disk_file::link): Ditto.
* fhandler_process.cc (fhandler_process::fill_filebuf): Always remove
.exe suffix.
* path.cc (realpath): Never attach known_suffix.
