MFC kern.msgbufsize: r217688-217689,r217709,r218666-218667,r218913.
Note, that arm/{s3c2xx0,econa} exist only in head, thus not merged.
r217688:
Make MSGBUF_SIZE kernel option a loader tunable kern.msgbufsize.
r217689:
Add kern.msgbufsize default setting to /boot/defaults/loader.conf.
r217709,218666-218667,218913 by marcel, cognet:
Fix up for various arm subtargets: call init_param1() before we use
msgbufsize, now that the size of the message buffer is a tunable.
