	* init.cc (dll_entry): Remove wow64_test_stack_marker.  Check for
	unusual stack address by testing stack addresses from current TEB.
	Check validity of _my_tls by testing if it's within the stack as
	given in current TEB.
	* miscfuncs.cc (struct thread_wrapper_arg): New structure used to
	push all required information to thread_wrapper function.
	(thread_wrapper): Wrapper function for actual thread function.
	If an application stack has been given, change %ebp and %esp so that
	the thread function runs on that stack.  If the thread has been created
	by CygwinCreateThread, set up the POSIX guard pages if necessary.
	(CygwinCreateThread): New function.
	* miscfuncs.h (CygwinCreateThread): Declare.
	* ntdll.h (struct _TEB): Define all members up to Peb.
	* posix.sgml (std-susv4): Move pthread_attr_getguardsize,
	pthread_attr_setguardsize and pthread_attr_setstack here.
	(std-deprec): Add pthread_attr_setstackaddr.
	* sysconf.cc (sca): Set _SC_THREAD_ATTR_STACKADDR to
	_POSIX_THREAD_ATTR_STACKADDR.
	* thread.cc (pthread::precreate): Copy pthread_attr stackaddr and
	guardsize members.
	(pthread::create): Call CygwinCreateThread.
	(pthread_attr::pthread_attr): Initialize guardsize.
	(pthread_attr_setstack): New function.
	(pthread_attr_setstackaddr): New function.
	(pthread_attr_setguardsize): New function.
	(pthread_attr_getguardsize): New function.
	(pthread_getattr_np): Copy attr.guardsize.
	* thread.h (pthread_attr): Add member guardsize.
	* include/pthread.h (pthread_attr_getguardsize): Declare.

Corinna Vinschen b4966f9139 * fhandler_process.cc (struct heap_info::heap): Convert base to
uintptr_t.  Add heap_id, end, flags members.
	(heap_info::heap_vm_chunks): Rename from heaps.
	(heap_info::heap_info): Rearrange using RtlQueryProcessDebugInformation
	to get information of heap virtual memory blocks.  Store heap id and
	flags, as well as end address of each block.
	(heap_info::fill_if_match): Check incoming base address against full
	address range of heap chunks.  Convert flag values in extra heap
	information.
	(format_process_maps): Change order so that heap check is done before
	MEM_MAPPED check since there are shareable heaps.
	* ntdll.h (PDI_HEAP_BLOCKS): Define.
