according to aforementioned changes.

condition from ReadConsoleOutputW. Add more debugging.

* pinfo.cc (pinfo::thisproc): Set ppid for redirected _pinfo blocks too.
(pinfo::init): Avoid using VirtualQuery. Just rely on the assumption that
procinfo will be populated.
* pinfo.h (_pinfo::ppid): Move into redirected block.
* fork.cc (frok::parent): When initializing pinfo for child new PID_NEW flag +
actual defined constant rather than raw number. Don't set start_time here.

checking h for NULL multiple times. Don't set start_time here.
(pinfo_init): Aways set ppid last. Tweak strace output.

useful information. Set start_time if PID_NEW.
(_onreturn:h): Define as HANDLE rather than HANDLE *.
(_onreturn::~onreturn): Accommodate h definition change.
(_onreturn::no_close_handle): Rename from no_close_p_handle. Take a pinfo arg

associated with when a handle gets closed. Accommodate no_close_handle
changes.
(winpids::enum_processes): Simplify process enumeration loop.
(winpids::set): Eliminate ill-considered malloc locking.
* sigproc.cc (proc_subproc): Always set ppid last.
(stop_transaction): Take "trans" HANDLE by reference and set it to
NULL after closing it.
(unlink_nt): If NtOpenFile fails due to a transactional error, stop
transaction and retry NtOpenFile. Simplify check for having to call
stop_transaction.
(rename): If NtOpenFile fails due to a transactional error, stop
transaction and retry NtOpenFile in both affected cases. Simplify check
for having to call stop_transaction and add comment from unlink_nt.
been set by a previous function.
* dtable.h (dtable::extend): Accept second size_t argument.
