Corinna Vinschen 2f2a75b7bb Cygwin: AF_UNIX: fix creation of npfs handle
The handle to the device is never needed.  As the name impies,
FSCTL_PIPE_WAIT works on the file system, not on the device level.

Drop opening the device and make sure to open only one handle to NPFS.

Corinna Vinschen e42f66d00f Remove ill-advised cygwin_props
Cygwin_props have been invented to allow switching off the unique
installation keys in the first place, supposedly for debugging.
This never really was a good idea, after all we *want* the installations
to be independent and there's no good reason to break that, not even
for debugging purposes.

Other than that, cygwin_props were meant to be used for some other global
settings which never took place.  There's just no good reason to tweak
the DLL binary invisibly where a setting could be done in a file or the
environment.

This patch removes the cygwin_props entirely, including the related
settings in cygcheck.

cygwin:
	* cygprops.h: Remove file.
	* globals.cc (cygwin_props): Remove.
	* cygheap.cc (init_cygheap::init_installation_root): Drop removing
	installation key.

utils:
	* cygcheck.cc: Drop including cygprops.h.  Remove now unused option
	values.
	(unique_object_name_opt): Remove.
	(handle_unique_object_name): Remove function.
	(usage): Remove text for unique-object-names options.
	(longopts): Remove unique-object-names options.
	(main): Drop handling unique-object-names options.

doc:
	* utils.xml (cygcheck): Remove text for unique-object-names options.

Christopher Faylor 45d7b637fa * dcrt0.cc (init_windows_system_directory): Record system_wow64_directory
information.
* exceptions.cc (_cygtls::inside_kernel): Modernize comment.  Consider
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
linux, consider the operation to be restartable if not executing in the main
thread.
* globals.cc (windows_system_directory): Remove NO_COPY.
(windows_system_directory_length): Ditto.
(system_wow64_directory): New variable.
(system_wow64_directory_length): Ditto.

seems to be what Linux does.  Add missing break to signal case/switch.

to be what Linux does.  Remove now-unneeded accommodation for
WAIT_IO_COMPLETION.  Add a comment.

not the main thread.

named constants.
(_PROC_*): Delete unneeded aliases.
(PROC_*): Ditto.
(CURR_CHILD_INFO_MAGIC): Ditto.
(cchildren): Define using "pinfo_minimal".
(child_info::set_saw_ctrl_c): Move to

(child_info_spawn::has_execed_cygwin): Ditto.

handle naming when -DDEBUGGING.
(pinfo::init): Accommodate case where myself.h is known but h0 is passed in.
(pinfo::pinfo): New constructor for setting up a pinfo passed in by previous
exec'or.
(pinfo::proc_waiter): Don't handle subprocess if we're in the process of
exiting due to an exec of a cygwin process.  Don't close rd_proc_pipe here.

in pinfo::release.

(child_info_spawn::record_children): Specifically test for being execed here.
Fill in pinfo_minimal part of children array.

(PROC_DETACHED_CHILD): Delete.
* spawn.cc (chExeced): Delete.
(child_info_spawn::worker): Rename from spawn_guts.  Use elements of
child_info_spawn throughout rather than ch.whatever.  Use ::cygheap to refer to

child_info_spawn::worker.
* syscalls.cc (popen): Ditto.
* winsup.h (spawn_guts): Delete declaration.

* sigproc.cc: Move pinfo.h earlier so that it can be used in sigproc.h.
(get_proc_lock): Don't bother with a lock during DLL initialization.
