sleep(3) expects this, even though it's not a documented property of
nanosleep().
Fixes a problem where sleep() in a threaded program would return
nonzero even on success.
the write to the ktraced file descriptor (when they used fktrace internally)
would block. Fix by clearing the non-blocking bit in the file descriptor by
default, so that the writes will block. This has the side effect of stopping
the traced process. Add a flag to override (-n) this behavior and have the
trace stop without blocking the traced process (the previous behavior).
Fix lint, add checks to failed syscalls, ansify.
due to andoc.tmac being generated here and it'll end up in the depend tree
for installation (during dependall) if DESTDIR=/ and USETOOLS=no/never which
will lose for most people. Fixes final part of PR#23067
for consistency with M_FREE() and m_freem(). Affected files:
sys/mbuf.h
kern/uipc_socket2.c
kern/uipc_mbuf.c
net/if_ethersubr.c
netatalk/ddp_input.c
nfs/nfs_socket.c
Device Reset Occurred") when the device is not opened. So let the default
error handler deal with that.
This fix the retrieval of the sense page during autoconfig.

a ktraced file descriptor that has already been invalidated. Change
all ktrace functions to propagate the error from ktrwrite() and
check for it. Thanks to Pavel Cahyna for finding this and giving
a perfect bug report.
[should be pulled up for 2.0]
USETOOLS=no/never means the system groff is being used so depending on
anything except it's tmac files makes no sense (and prevents builds with
USETOOLS=no/never from working as PR#23067 points out)
may retry it as a memory read multiple command under some circumstances.
This can totally confuse some PCI controllers, so ensure that it
will never do this by making sure that the Read Threshold (FIFO
Read Request Control) field of the FIFO Valid Byte Count and Control
registers for both channels (BA5 offset 0x40 and 0x44) are set to
be at least as large as the cacheline size register (the unit of
measure for these registers is 32 bytes).
