Submit #1700: skip boot2 menu on <enter>

Hi,

tuxillo noticed that the trick to speedup booting by hitting <enter>
does not work with default UFS-based installations, as those have no
separate /boot partition, and therefore the default location for the
loader is wrong (it had been changed to match default HAMMER
installations in commit:3735e368a1bdbe773c79c34512f49c905ff77bd7)

We could change boot2 to just continue it's normal operation without
entering the prompt when the user hits <enter>. That way one can avoid
the delay on UFS and HAMMER systems:

<pre>
<code class="ruby">
diff --git a/sys/boot/pc32/boot2/boot2.c b/sys/boot/pc32/boot2/boot2.c
index 459436f..55516be 100644
--- a/sys/boot/pc32/boot2/boot2.c
+++ b/sys/boot/pc32/boot2/boot2.c

      */
     if (autoboot && !*kname) {
 	memcpy(kname, PATH_BOOT3, sizeof(PATH_BOOT3));
-	if (!keyhit(3*SECOND)) {
+	if (!keyhit(3*SECOND) || xgetc(0) == '\r') {
 	    load();
 	    memcpy(kname, PATH_BOOT3_ALT, sizeof(PATH_BOOT3_ALT));
 	    load();

</code>
</pre>

To actually enter the prompt one has to hit any other key (e.g. Esc).

The check for '\r' works ok for me, but maybe we also need to check
for '\n'?

Cheers,
Johannes
