* gdb.base/signull.c: Update copyright.  Include <string.h>.
	(bowler): Replace data_pointer with data_read
	and data_write cases.  Add code_descriptor case.
	(zero, desc): New array and pointer.
	(data, code): Change to simple pointers.
	* gdb.base/signull.exp: Fix probe pattern matching a function
	descriptor SIGSEGV.  Replace data_pointer with data_read and
	data_write tests.
