Throughout use wincap.allocation_granularity instead of getpagesize.

Throughout use wincap.page_size instead of getsystempagesize.
	Throughout use "status" as variable name to hold NTSTATUS values.
	* fhandler_mem.cc: Check for NT_SUCCESS rather than for STATUS_SUCCESS.
	Fix debug_printf output.  Rectify long statements.  Fix comment
	formatting.
	* fhandler_proc.cc: Ditto.
	(format_proc_swaps): Drop useless test for ERROR_PROC_NOT_FOUND.
	* fhandler_process.cc: Ditto as in fhandler_mem.cc.
	(get_process_state): Rearrange allocation loop.  Use malloc/realloc.
	(get_mem_values): Fix potential NULL pointer usage.  Drop unused
	variable.
	* pinfo.cc (winpids::enum_processes): Handle low memory gracefully.
	* sec_auth.cc (get_priv_list): Drop local variable ret.
	* shared.cc (memory_init): Drop outdated call to getpagesize.
	* syscalls.cc (getsystempagesize): Remove.
	* sysconf.cc: Check for NT_SUCCESS rather than for STATUS_SUCCESS.
	(sysinfo): Constify sizeof_stodi.  Drop useless test for
	ERROR_PROC_NOT_FOUND.
	* thread.cc (pthread_getattr_np): Cast pointers to uintptr_t rather
	than to int for pointer arithmetic.
	* winsup.h (getsystempagesize): Drop declaration.
