* fhandler.h (fhandler_base::get_stat_access): Delete.

Browse Source 
* fhandler_disk_file.cc (fhandler_base::fstat_helper): Always check
	executable suffix to get x-bits for .exe files also in notexec case.
	Always reopen file when checking for file header.
	* ntdll.h (wait_pending): Delete.
	* path.cc (symlink_info::check_shortcut): Drop call to wait_pending
	since file is always opened for sync IO.
	(symlink_info::check_sysfile): Ditto.
	(MIN_STAT_ACCESS): Remove.
	(FULL_STAT_ACCESS): Remove.
	(symlink_info::check): Drop access flag.  Revert to open file with
	just read attributes access.  Reorder symlink check to check for
	reparse points first.  Don't check reparse points for anything else,
	even on remote drives.  Open file for GENERIC_READ when trying to
	read shortcuts or system-bit symlinks. Accommodate dropped access
	flag in call to path_conv_handle::set.
	* path.h (class path_conv_handle): Drop access flag and accommodate
	all related methods.
