* path.cc (path_conv::check): Add signal protection here since retrieving info
about remote shares can take some time.
* path.h (check_null_empty_str_errno): Convert to a function prototype.
* path.cc (check_null_empty_str): Move to miscfuncs.cc.
* miscfuncs.cc (check_null_empty_str_errno): New function.
(__check_null_invalid_struct): Ditto.
(__check_null_invalid_struct_errno): Ditto.
(check_null_empty_str): Change from VirtualQuery to IsBadWritePtr.
* thread.cc (check_valid_pointer): Ditto.
* resource.cc (getrlimit): Use check_null_invalid_struct macro for checking
validity of pointer.
(setrlimit): Ditto.
being read for executable test since we could be checking for less than that.
* syscalls.cc (stat_worker): Try opening the file the "correct" way first so
that #! processing can potentially happen. If that fails, then use "query
open" method.
* spawn.cc (spawn_guts): Delay processing of signal until after we've notified
parent about reparenting.
* thread.cc (pthread_cond::TimedWait): Check for WAIT_TIMEOUT as well as
WAIT_ABANDONED.
(__pthread_cond_timedwait): Calculate a relative wait from the abstime
parameter.
(setup_handler): Move actions after a successful interrupt to interrupt_setup.
* fork.cc (vfork): Augment debugging output.
* sigproc.cc (proc_subproc): Ditto.
* spawn.cc (spawn_guts): Ditto. Correctly fill out progname when spawn
NO_WAIT. Call signal handler when a signal arrives.
* sigproc.h: Declare a function.
* thread.cc (__pthread_cond_timedwait): Lock the waiting mutex before
the condition protect mutex to avoid deadlocking. (Found by Greg Smith).
(__pthread_cond_wait): Ditto.
function.
* fhandler.h: Declare it.
* fhandler_socket.cc (fhandler_socket::create_secret_event): Don't
signal secret event immediately.
(fhandler_socket::check_peer_secret_event): Do it after peer event
was opened.
* net.cc (cygwin_connect): Or if socket is non-blocking.
(cygwin_accept): Ditto.
* fork.cc (fork_copy): Print more debugging info.
(fork_parent): Change order of arguments to accomdate buggy gcc.
(fork): Ditto.
* syscalls.cc (_unlink): Reorganize to try harder to delete file with
DeleteFile and to recover more gracefully if FILE_FLAG_DELETE_ON_CLOSE doesn't
work properly.

* fhandler_console.cc (fhandler_console::fixup_after_fork): Don't set
controlling terminal if just inheriting a handle.
(fhandler_console::fixup_after_exec): Ditto.
* fhandler_tty.cc (fhandler_tty_slave::init): Ditto.
* signal.cc (kill_worker): Set appropriate errno if proc_exists determines that
process does not really exist.
