[patch] Gdbserver error codes
- From: Daniel Jacobowitz <drow at false dot org>

- Subject: [patch] Gdbserver error codes
Thanks to Eli for making me look closer at this. Parts of remote.c
will reject ENN; in particular, ENN will cause remote_write_bytes to return
an error but remote_read_bytes not to. Thus the 0xffffffff gdbserver has
been printing instead of an error message for inaccessible memory regions.
Also updated some copyright dates. Checked in.

* remote-utils.c (write_enn): Use "E01" instead of "ENN" for the
error packet.
* server.c, target.h: Update copyright years.
