* path.h (class path_conv): Add a char * operator for the most common case.
* syscalls.cc (_unlink): Rewrite to use FILE_FLAG_DELETE_ON_CLOSE when possible
(i.e., on NT).
(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): 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
of GetVolumeInformation().
(mount_info::conv_to_win32_path): Call backslashify() with pathbuf
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.
(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.
* exceptions.cc (sfta): Eliminate obsolete function.
(sgmb): Eliminate obsolete function.
(class stack_info): Remove MS method for walking the stack.
(stack_info::init): Just initialize required fields.
(stack_info::brute_force): Rename to stack_info::walk.
(handle_exceptions): Pass derived frame pointer to sig_send.
(interrupt_setup): Clear saved frame pointer here.
(interrupt_on_return): thestack is no longer a pointer.
(call_handler): Accept a flag to indicate when a signal was sent from other
than the main thread. Use saved frame pointer for determining where to place
signal handler call.
(sig_handle): Accept "nonmain" argument. Pass it to call_handler.
* fhandler_tty.cc (fhandler_tty_common::__acquire_output_mutex): Change
debugging output slightly.
* (fhandler_tty_common::__release_output_mutex): Ditto.
(fhandler_tty_slave::read): Fix a comment, remove a goto.
* sigproc.cc (sig_send): Accept an optional frame pointer argument for use when
suspending the main process. sigcomplete_main is an autoreset event now. Save
frame pointer for non-main operation.
(wait_sig): Make sigcomplete_main an autoreset event. Eliminate NOSIGQUEUE.
Pass rc to sig_handle to signify if this was a nonmain process.
* sigproc.h: Reflect change to sig_send argument.
