passes the device string.

* strptime(3) was introduced in XPG 4.0
* clock_gettime(3) and friends were introduced in 1003.1b-1993
* asctime_r(3) and friends were introduced in 1003.1c-1995

This makes our <time.h> standards compliant except for some functions that are
still missing.

friends in <time.h>.  The kernel needs access to the associated #defines, but
can't get them from <time.h>, so introduce a new header <sys/_time.h> and
include that from <time.h> for userland and <sys/time.h> for the kernel.

explaining of "what a C string is", and make it more clear that these
functiosn BEHAVE EXACTLY LIKE snprintf with "%s"!  (anyone who wants
to write a 'strlcpy considered harmful' paper should probably write a
'strlcpy and snprintf considered harmful' paper instead).

be very good if this new manual was picked up in your project.

older PROM and what to do about this.

(IP20, IP22, IP24) in 64-bit mode, adapated from NetBSD. Currently limited
to headless operation, input and video drivers will get ported soon.
Should work on all R4000, R4440 and R5000 based systems. L2 cache on R5000SC
Indy not supported yet (coming soon), R4600 not supported yet either (coming
soon as well).
Tested to boot multiuser on: Indigo2 R4000SC, Indy R4000PC, Indy R4000SC,
Indy R5000SC, Indigo2 R4400SC. There are still glitches in the Ethernet driver
which are being looked at.
Expansion support is limited to the GIO E++ board; GIO boards with PCI-GIO
bridges not ported yet due to the lack of hardware, and this kind of driver
does not port blindly.
Most of this work comes from NetBSD, polishing and integration work, as well
as putting as many ``R4x00 in 64-bit mode'' erratas as necessary, by yours
truly.
More work is coming, as well as trying to get some easy way to boot install
kernels (as older PROM can only boot ECOFF binaries, which won't do for the
kernel).
