* printcmd.c (disassemble_command): Remove obsolete function.

Browse source 
(_initialize_printcmd): Do not create disassemble command here.
	* cli/cli-cmds.c (disassemble_command): New function.  Implements
	disassemble command.
	(init_cli_cmds): Create disassemble command here instead.

	* gdb.asm/asm-source.exp: Adjust patter to new disassembler routine
	which explicitly prints the zero offset as "+0".
