Fix LP64BE bug.
fix rev 1.44; make this cast look like:
	sig = (int)(long)*(caddr_t *)data;
to *properly* dereference the passed data.  this makes signals on
ptys actually *work* on the sparc64 port.  from mycroft.


XXX: the release branch version needs this ASAP as it is probably
unstable on ILP32BE.
Handle booting without a serial expander box connected.
Avoid recursion with traditional cpp.
Comment tidying
Several clarifications.
no trailing , on last item in enum
rename "opts" to "remopts", so people used to "o host" don't get bitten...

wtmp is in /var/log not /var/run ...
Avoid a nonstandard %: format: printf("%:", fmt, ap) -> vprintf(fmt, ap)
Prototype netintr().
Eliminate the other %:, using vsnprintf followed by printf.
Fix CTRL-T to behave properly. It should swaps the current and previous

skey_keyinfo() returns a pointer to a static buffer, so
const'ify it.
skey_keyinfo() returns const.
Rename ssh_config to ssh.conf and sshd_config to sshd.conf, for
consistency with other NetBSD configuration files, and to avoid
clashes with other SSH implementations.
Control registers on sparc v9 start with PC_REGNUM not Y_REGNUM since
%pc and %npc are stored in %tpc and %tnpc rather than %l1 and %l2.
Don't dump if there's no address space reserved for it.
