* cygthread.cc (cygthread::create): Fix incorrect use of name rather than

__name.
* cygthread.h (cygthread::cygthread): Create versions which eliminate 'n'
parameter.
* dcrt0.cc (dll_crt0_1): Remove check for threadfunc_ix.  Remove obsolete
comments.  Set process_state to active here.
* fhandler_netdrive.cc (create_thread_and_wait): Use shortened cygthread
constructor.
* timer.cc (timer_tracker::settime): Ditto.
* window.cc (HWND): Ditto.
* fhandler_tty.cc: Use shortened cygthread constructor, where appropriate,
throughout.

* fork.cc (frok::child): Remove wait_for_sigthread.
(fork): Reformat if for slightly better clarity.
* init.cc (dll_finished_loading): New variable.
(dll_entry): Use dll_finished_loading to determine when we should call
merge_threadfunc.
* sigproc.cc (no_signals_available): Simplify by using my_readsig.
(wait_sig_inited): Delete.
(wait_sig): Define as void function.
(pending_signals): Accommodate change to wait_sig definition.
(wait_for_sigthread): Delete definition.
(sigproc_init): Initialize signal pipe here, before wait_sig thread is created.
Use void form of cygthread creation.
(init_sig_pipe): Delete.
(wait_sig): Return void rather than DWORD.  Assume previous initialization of
signal pipe.  Set my_sendsig to NULL when exiting.
* sigproc.h (wait_for_sigthread): Delete declaration.
