handler.
	* cygtls.cc (_cygtls::remove): Accommodate the fact that pathbufs
	has been moved from _local_storage to _cygtls.
	* cygtls.h (class tls_pathbuf): Add comment to hint to gendef usage
	of counters.  Change type of counters to uint32_t for clarity.
	Remove _cygtls as friend class.
	(struct _local_storage): Move pathbufs from here...
	(struct _cygtls): ...to here, allowing to access it from _sigbe.
	(class san): Only define on 32 bit.  Remove errno, _c_cnt and _w_cnt
	members.
	(san::setup): Drop parameter.  Don't initialize removed members.
	(san::leave): Don't set removed members.
	(class myfault): Only define on 32 bit.
	(myfault::faulted): Only keep implementation not taking any parameter.
	Drop argument in call to sebastian.setup.
	(__try/__leave/__except/__endtry): Implement to support real SEH.  For
	now stick to SJLJ on 32 bit.
	* dcrt0.cc (dll_crt0_0): Drop 64 bit call to
	exception::install_myfault_handler.
	* exception.h (exception_handler): Define with EXCEPTION_DISPOSITION
	as return type.
	(PDISPATCHER_CONTEXT): Define as void * on 32 bit.  Define as pointer
	to _DISPATCHER_CONTEXT on 64 bit.
	(class exception): Define separately for 32 and 64 bit.
	(exception::myfault): Add handler for myfault SEH handling on 64 bit.
	(exception::exception): Fix mangled method name to account for change
	in type of last parameter.
	(exception::install_myfault_handler): Remove.
	* exceptions.cc (exception::myfault_handle): Remove.
	(exception::myfault): New SEH handler for 64 bit.
	* gendef (_sigbe): Set tls_pathbuf counters to 0 explicitely when
	returning to the caller.
	* ntdll.h: Move a comment to a better place.
	(struct _SCOPE_TABLE): Define on 64 bit.
	* thread.cc (verifyable_object_isvalid): Remove gcc 4.7 workaround.
	* tls_pbuf.cc (tls_pbuf): Fix to accommodate new place of pathbufs.
	(tls_pathbuf::destroy): Change type of loop variables to uint32_t.
	* tls_pbuf.h (class tmp_pathbuf): Change type of buffer counters to
	uint32_t.  Accommodate new place of pathbufs.
	* tlsoffsets.h: Regenerate.
	* tlsoffsets64.h: Regenerate.
