Christopher Faylor 92ddb74290 * cygheap.cc (cygheap::close_ctty): Close ctty via close_with_arch(). 
* debug.cc (close_handle): Call debugger on failure.
* devices.in (device::tty_to_real_device): Delete.
* devices.h (device::tty_to_real_device): Ditto.
* devices.cc: Regenerate.
* dtable.cc: Delete old ifdef'ed vfork code.
(dtable::release): Don't handle archetype here.
(dtable::init_std_file_from_handle): Consolidate console tests.  Generate
major/minor for tty ASAP.  Fix incorrect setting of DEV_TTYS* for serial.
(fh_alloc): New function derived from build_fh_pc.  Pass current tty when
building tty.
(build_pc_pc): Use fh_alloc to create.  Set name from fh->dev if appropriate.
Generate an archetype or point to one here.
(dtable::dup_worker): Deal with archetypes.  Rely on = operator copying whole
class rather than just fhandler_base.
(dtable::fixup_after_exec): Call close_with_arch to handle closing of fhandlers
with archetypes.
* fhandler.cc (fhandler_base::operator =): Call memcpy with fhandler's size()
rather than sizeof fhandler_base.
(fhandler_base::open_with_arch): New function.  Handles opening of fhandler's
with archetypes, dealing with usecounts, etc.
(fhandler_base::close_with_arch): Ditto for close.
* fhandler.h: Many changes for archetypes.
(fhandler_base::set_name): Set both normalized path and regular path.
(fhandler_base::open_with_arch): New function.

(fhandler_tty_slave::cleanup): New function.
(fhandler_pty_master::use_archetype): New function.  Return true.
(fhandler_pty_master::cleanup): New function.
(fhandler_pty_master::is_tty_master): New function.  Return false.
(fhandler_tty_master::is_tty_master): New function.  Return true.
(fhandler_dev_dsp::fhandler_dev_dsp): New function.  Return true.
(report_tty_counts): Only report on archetype's usecount if there is one.
* fhandler_console.cc (fhandler_console::get_tty_stuff): Remove handling of
setsid, set_ctty, set_flags, and manage_console_count.
(fhandler_console::open_setup): New function.  Implement functionality removed
from get_tty_stuff.
(fhandler_console::dup): Delete.
(fhandler_console::output_tcsetattr): Set errno on error.
(fhandler_console::fhandler_console): Set device early.
(fhandler_console::init): Use open_with_arch to open console handles.
(fhandler_console::fixup_after_fork_exec): Nuke most of the stuff for dealing
with console handles.
* fhandler_dsp.cc (fhandler_dev_dsp::open): Remove archetype handling.

more debugging.
(fhandler_tty_common::__release_output_mutex): Ditto.
(fhandler_pty_master::process_slave_output): Ditto.  Don't do signal handling
or pthread_cancel handling in the tty master thread.
(process_output): Minor reorg.
(fhandler_tty_slave::fhandler_tty_slave): Set device based on new ntty
argument.
(fhandler_tty_slave::open): Remove archetype handling.  Move some processing
into open_setup().
(fhandler_tty_slave::open_setup): New function.
(fhandler_tty_slave::cleanup): New function.
(fhandler_tty_slave::close): Remove archetype handling.  Move some processing
into cleanup().
(fhandler_tty_slave::init): Rename argument from f to h.  Open device using
open_with_arch().  Remove archetype handling.
(fhandler_pty_master::dup): Ditto.
(fhandler_pty_master::open): Ditto.
(fhandler_pty_master::close): Ditto.  Move some handling to cleanup().
(fhandler_pty_master::cleanup): New function.

fhandler.
* pinfo.cc (_pinfo::set_ctty): Rename argument from arch to fh.  Eliminate
archetype assumption.
