when determining exec flag.
* path.cc (symlink_info::check): Remove call to get_file_attribute().

to common naming convention. Use GetFileSecurity() instead of
BackupRead() to avoid permission problems when reading ACLs.

for group and world when write permission is set.
* syscalls.cc (stat_worker): Avoid different permission problems
when requesting file informations.
(get_nt_attribute): Returns uid and gid additionally. Removed call
to set_process_privileges().
(get_file_attribute): Returns uid and gid additionally. Don't
call ntea if ntsec is ON.
(set_nt_attribute): Removed call to set_process_privileges().
Don't call ntea if ntsec is ON.

* dcrt0.cc (dll_crt0_1): Calls set_process_privileges() now.

* fhandler.cc (get_file_owner): Discarded.
(get_file_group): Ditto.
(fhandler_disk_file::fstat): Discard calls to get_file_owner() and
get_file_group().
* path.cc (path_conv::path_conv): Added debugging output for result

instead of src_path.
* syscalls.cc (chown): Reformatted.
(chmod): Replace get_file_owner() and get_file_group() calls
by a call to get_file_attribute(). Discard local variable has_acls.
Slightly reformatted.
