Eliminate is_cancelable. Don't element 1 of an array if it is a cancel handle.

the bottom.

(select_stuff::wait): Modify declaration to return select_stuff::wait_states.

handler.

wr_proc_pipe and parent noninheritable when starting a program which doesn't
use the Cygwin DLL. Conditionally reset wr_proc_pipe to inheritable if
CreateProcess fails. Inject wr_proc_pipe handle into non-Cygwin process.
Consider a non-cygwin process to be 'synced'.
* fhandler_tty.cc (bytes_available): Revert to previous Oct-2011 behavior where
a dummy buffer is used to determine how many bytes will be read.

has_gaa_largeaddress_bug member to false on 32 bit systems.
* sigproc.cc (proc_terminate): Don't set parent pid of child to 1 if we've
execed since the execed process is still considered the parent.

every pipe since some pipe names (fifo, tty) don't need it.
* sigproc.cc (sigproc_init): Pass PIPE_ADD_PID to fhandler_pipe::create to
ensure that pid is always part of sigwait pipe name.
* globals.cc (pipe_byte): Declare.
* pipe.cc (fhandler_pipe::create): Use current process id in pipe name rather
than pid for simple name collision avoidance. Do this only once to avoid extra
overhead when a busy pipe is found. Honor pipe_byte to create non-message
pipes if set.
* sigproc.cc (sigproc_init): Use a specific name for the signal pipe.

and have_execed_cygwin.

fhandler_console::exists () rather than raw test.

process in its own process group. Just do it whenever we start a non-Cygwin
process.
ENOENT if non-existent file got opened for reading only. Explain why.
* path.cc (path_conv::check): Stick to ENOENT if file has been opened
for informational purposes only. Add to comment.
(getpass): Rework to use /dev/tty in the first place. Install
_getpass_close_fd as pthread cleanup handler. Flush prompt explicitely.
Lock input and switch off signal input handling when reading password.
(dev_on_fs): Set bit size.
(is_dev_resident): Define new method.
