* environ.cc (struct parse_thing): Add transparent_exe option.

Browse Source 
* fhandler_disk_file.cc (fhandler_disk_file::link): Accomodate
	transparent_exe option.  Add .exe suffix for links to executable files,
	if transparent_exe is set.
	* fhandler_process.cc (fhandler_process::fill_filebuf): Remove .exe
	suffix if transparent_exe option is set.
	* path.cc (symlink_worker): Accomodate transparent_exe option.
	(realpath): Don't tack on .exe suffix if transparent_exe is set.
	* syscalls.cc (transparent_exe): New global variable.
	(unlink): Accomodate transparent_exe option.
	(open): Ditto.
	(link): Ditto.
	(rename): Ditto. Maybe add .exe suffix when renaming executable files.
	(pathconf): Accomodate transparent_exe option.
	* winsup.h: Declare transparent_exe.
