executing a DLL from the Wow64 directory as being "in the kernel".
(_cygtls::call_signal_handler): For now, only deal with main_tls signals if
main_tls is known to be executing in the cygwin DLL. To more closely emulate

to be what Linux does. Remove now-unneeded accommodation for

not the main thread.

(wow64_started_from_native64): New function to check if a WOW64
process got started from a native 64 bit process.
(respawn_wow64_process): New function to respawn process.
(dll_crt0_0): When started from a native parent, check if parent
is a 64 bit process. If so, return early.

(pipe_worker): New function created from _pipe().
(_pipe): Use pipe_worker to create a pipe. Use standard syscall strace

(pipe): Ditto.
(pipe2): Ditto.
(peek_windows): Report on HWND handle used in queries.
* select.h: Update copyright.
* sigproc.h (cygwait): Eliminate multi-argument variety since more general
implementation may cause odd problems in select. Also force to always be
inline.
_my_tls.remove along with a comment.
(sigpacket::process): Remove code which now causes a gdb deadlock.
* sigproc.cc (_cygtls::signal_exit): Signal debugger with signal number
earlier.

* fhandler_serial.cc (fhandler_serial::raw_read): Ditto.
(fhandler_serial::raw_write): Ditto.
* select.cc (cygwin_select): Ditto.
* sigproc.h (cygwait): Rename from cygWFMO. Define two argument and single
argument forms of this function.
* fhandler_tty.cc (fhandler_pty_slave::open): Use method to query if tty is
open.
(fhandler_pty_slave::read): Send SIGHUP when master is detected as closed.
(fhandler_pty_common::close): Close input_available_event in callers since
master may need to signal it first.
(fhandler_pty_master::close): Lie and set input_available_event when closing,
then close input_available_event.
(fhandler_pty_slave::close): Close input_available_event explicitly here.
