Leave errno as-is if fstat(2) fails instead of masking the real
errno with ENOTDIR.  From Tim van der Molen.
Better ERRORS section info; from Tim van der Molen.  POSIX documents
other common errno values for opendir() whereas we just point the

Compute the right value for hw.ncpusfound sysctl on IP30 regardless of the
value of MAXCPUS.
Build GENERIC-IP30.MP as bsd.mp.IP30 in the distribution, and allow the
installer to pick it and install it as /bsd when applicable.
Permit !, + and - to be used for window targets to specify last window (!), or
next and previous window by number (+ and -).

Also tidy an if in cmd-new-window.c.
Remove horrible hack in ahc/ahd that made some commands retry
endlessly.  Use the shiny new XS_NO_CCB instead to retry commands
that can't start. Neither dlg@ nor I can figure out why 4.6 and
earlier worked.

Problem noted, debugged with and fix tested by Jeff Ross and his
new external enclosure. Thanks!

Make ypserv(8) reread its YP maps on SIGHUP
and use that in Makefile.yp(8) at the end of   cd /var/yp; make all
such that the new maps get used locally even when NOPUSH is set;
fixing a quirk reported by ian@.

While here, polish the yppush(8) manual
and document a few related mini-bugs to be fixed later.

Pick the correct year when reading clock.
Use db_printf() instead of printf() in db_dump_tlb_cmd() and trapDump(), so
that the output can be paused by ddb if it spans too many lines.
*Write* to the magic Loongson2 register to invalidate iTLB and branch
prediction caches, instead of *reading* it. Ahem. Blush.
