* path.cc (symlink_info::check): Rename from symlink_check_one. Use new
symlink_info struct for communication.
(path_conv::path_conv): Use symlink_info structure for communication with
symlink_info::check. Fix typo which resulted in symbolic links always being
resolved.
(readlink): Use stat_suffixes array when resolving a link.
* syscalls.cc (stat_suffixes): Make global.
(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.
(acl): Removed call to set_process_privileges().
* dcrt0.cc (dll_crt0_1): Calls set_process_privileges() now.
* winsup.h: New prototype for set_process_privileges(),
changed prototype for get_file_attribute().
* fhandler.cc (get_file_owner): Discarded.

get_file_group().

instead of src_path.

by a call to get_file_attribute(). Discard local variable has_acls.
Slightly reformatted.
(stat_worker): Replaced idiot's (it's me) root dir check by call
to rootdir(). Don't call num_entries() on remote drives.
Discard local variable has_acls.
(getprogname): Eliminate obsolete function.
(dll_crt0_1): Move initial strace initialization output to set_myself.
* exceptions.cc (interruptible): Add debugging output.
(interrupt_setup): New function.
(interrupt_now): Use interrupt_setup to set up common interrupt handler stuff.
(interrupt_on_return): Ditto.
(call_handler): Move signal_arrived arm and clear threads to region where
signalled thread is suspended or suffer races.
