(set_process_mask_delta): Ditto.
(_cygtls::call_signal_handler): Ditto.
* fhandler_disk_file.cc (fhandler_disk_file::readdir): Return ENMFILE if
__handle is not set. Set __handle to NULL when out of files.
(fhandler_disk_file::rewinddir): Don't close handle if it's NULL.
(fhandler_disk_file::closedir): Ditto.
dirent_saw_dev.
* dir.cc (opendir): Don't zero __flags here. Push that responsibility to
opendir methods.
(seekdir): Preserve dirent_isrrot in __flags.
(rewinddir): Ditto.
* fhandler_disk_file.cc (fhandler_disk_file::opendir): Set dirent_isroot
appropriately.
(fhandler_disk_file::readdir): Fill in "cygdrive" and "dev" if it is the root
dir and they are missing.

(fhandler_tty_slave::lseek): Delete old method.
(fhandler_tty_master::lseek): Delete old method.
* fhandler_tty.cc (fhandler_tty_common::lseek): Define new method.
* fhandler_tty.cc (fhandler_tty_common::close): Rearrange the code so that the
master end of the input and output pipes is closed before signalling an EOF
event to the slave.
(fhandler_pty_master::close): Likewise.
"noreturn" attribute. Add additional check if parent process is
actually a 64 bit process.
(dll_entry): Only test WOW64 processes with a stack in the usual
"dangerous" process space area.
(child_info::child_info()): New constructor.
(child_info_spawn::child_info_spawn()): Ditto.

(child_info_spawn::set): New function.
* spawn.cc (av()): New constructor.
(av::operator new): New operator.
(av::set): New function.
(spawn_guts): Reorganize so that classes which allocates are defined early in
the function so that it can be properly cleaned up after an efault. Set errno
to E2BIG in the event of a SEGV situation.
* dllfixdbg: Just copy .stab and .stabstr sections when making cygwin1.dbg,
rather than relying on objcopy to keep only the debug sections since objcopy
seems to get it wrong.
* dtable.cc (build_fh_pc): Check setting fh to fhandler_nodevice for NULL, too.
* cygheap.cc (cmalloc): Only emit system_printf warnings on failure if
DEBUGGING.
(crealloc): Ditto.
(ccalloc): Ditto.
* dtable.cc (build_fh_name): Treat NULL return from cnew as indicative of
EMFILE condition.
(build_fh_dev): Ditto.
(dtable::dup_worker): Handle NULL return from build_fh_pc.
(dtable::vfork_child_dup): Trust dup_worker to set errno.
* fhandler.h (fhandler_base::new): Mark as nothrow.
linux.
* include/cygwin/types.h: Include endian.h.
* include/sys/dirent.h: Define DT_* types and conversion macros.
* pinfo.cc (pinfo::init): Remove special handling for PID_ALLPIDS and execed
code, even though it probably still isn't quite right.
* fhandler.h (class fhandler_serial): Declare switch_modem_lines.
* fhandler_serial.cc (fhandler_serial::switch_modem_lines): New
static function to set or clear DTR and/or RTS.
(fhandler_serial::ioctl): Use switch_modem_lines for TIOCMSET
and new TIOCMBIS and TIOCMBIC.
* include/cygwin/version.h: Bump API minor number.
(child_info::child_info): Accept an argument controlling whether to create
proc_subproc.
(child_info_spawn::child_info_spawn): Ditto.
* sigproc.cc (child_info::child_info): Ditto.
(child_info_spawn::child_info_spawn): Ditto.
(child_info::sync): Use passed in pid and HANDLE.
* fork.cc (fork_parent): Reflect additional arguments required for
child_info::sync.
* hookapi.cc (hook_or_detect_cygwin): Rename. Change so that NULL 'fn'
argument just returns "true", indicating that program uses cygwin1.dll.
* spawn.cc (av::win16_exe): New element.
* spawn.cc (av::iscygwin): New element.
(av::fixup): New function.
(spawn_guts): Protect against SEGV. Use fixup function to detect when it is
safe to wait for a spawned (as opposed to an execed) program. Reflect changes
in child_info::sync arguments.
* external.cc (cygwin_internal): Reflect function renaming to
hook_or_detect_cygwin.
* cygheap.cc (cygheap_fixup_in_child): Close handle after debug fixup has been
done to prevent false positives in handle collision.
