Minor improvements in 'restart-emacs' on MS-Windows

* src/w32.c (w32_reexec_emacs): Explicitly request a new console
for the restarted Emacs -nw, and specify its dimensions.  Specify
NULL instead of security attributes, per examples on the Internet.
* src/w32console.c (initialize_w32_display): Check errors in call
to GetConsoleCursorInfo.
