[COMMIT PATCH] Make "set/show remoteaddresssize" a zuinteger command instead of uinteger.

[Pedro Alves <palves at redhat dot com>]

It makes no sense to talk about an "unlimited" address size in this
context.

 (gdb) show remoteaddresssize
 The maximum size of the address (in bits) in a memory packet is 0.
 (gdb) set remoteaddresssize 0
 (gdb) show remoteaddresssize
 The maximum size of the address (in bits) in a memory packet is unlimited.

"set remoteaddresssize 0" mapping to UINT_MAX means you can't
force gdb through this path twice in the same GDB run:

  static CORE_ADDR
  remote_address_masked (CORE_ADDR addr)
  {
    unsigned int address_size = remote_address_size;

    /* If "remoteaddresssize" was not set, default to target address size.  */
    if (!address_size)
      address_size = gdbarch_addr_bit (target_gdbarch ());

	* remote.c (_initialize_remote): Make "set remoteaddresssize"
	a zuinteger command instead of uinteger.
