* Makefile.in: Use variables rather than configure constructs where

appropriate.
(LIBCOS): Find additional stub library stuff in their own subdirectory.
* dcrt0.cc: Convert user_data pointer to static __cygwin_user_data area.
(do_global_ctors): Check magic_bisquit for initialization.
(dll_crt0_1): First group of premain functions prior to fd initialization.  Run
second group before calling main.
(dll_crt0 ()): New function, called from new initialization code.
(dll_crt0 (per_process *uptr)): Call new dll_crt0 () function on
initialization.
* debug.cc (thread_stub): Initialize bottom of stack with per-thread info.
* environ.cc (parse_thing): Use binmode global to control CYGWIN=binmode
behavior.
* fhandler.cc (fhandler_base::open): Allow explicit setting of __fmode to
O_BINARY or O_TEXT to override disk mount settings.
* libcmain.cc: Move to lib subdirectory.
* libccrt0.cc: Ditto.
* dll_main.cc: Ditto.
* dll_entry.cc: Ditto.
* getopt.c: Ditto.
* thread.cc (thread_init_wrapper): Call ExitThread explicitly rather than
returning, as a preliminary step towards placing per thread info at the bottom
of the stack.
* winsup.h: Move per_process class to include/sys/cygwin.h.  Declare new
dll_crt0().
* include/cygwin/version.h: Bump API minor version.
* binmode.c: New file.
* textmode.c: Ditto.
