	with additional flags parameter.  Change offset parameter to _off64_t.
	(class fhandler_disk_file): Ditto.
	(class fhandler_dev_mem): Ditto.
	* fhandler_mem.cc (fhandler_dev_mem::fixup_mmap_after_fork):
	Accomodate new parameters.
	* mmap.cc: Include ntdll.h.
	(class mmap_record): Add flags member.
	(mmap_record::mmap_record): Add flags parameter.
	(mmap_record::get_flags): New method.
	(class map): Add next_anon_addr member to store next anonymous mapping
	address suggestion.
	(map::get_next_anon_addr): New method.
	(map::set_next_anon_addr): New method.
	(mmap64): Don't align offset and length to granularity in case of

	Call mmap_record::mmap_record with additional flags argument.
	(fhandler_base::fixup_mmap_after_fork): Accomodate new parameters.
	(fhandler_disk_file::mmap): Use NtMapViewOfSection with
