This fixes infinite restart in the following case:
Makefile: foo
foo: bar

Unlike GNU make, BSD make considers "Makefile" node as remade even
if "foo" is up-to-date and was not actually rebuilt.
GNU make does not consider nodes without commands as remade if child nodes
were not actually rebuilt.
Most probably, more proper fix would be to bring BSD make behaviour in-line
with GNU make but this would be more intrusive change.
be applied to dev entries. This leaves us with file times like "Jan 1 1970."
Work around this problem by replacing the tv_sec == 0 check with a
<= 3600 check. It's doubtful anyone will be booting within an hour of the
Epoch, let alone care about a few seconds worth of nonzero timestamps. It's
a hackish work around, but it does work and I have not experienced any
negatives in my testing.

and new SCBs were allocated on demand later if needed. This has two
problems. First, allocating SCBs involves allocating contiguous memory,
and if memory is exhausted then the VM will try to page out to satisfy
the request, leading to recursion and deadlock. The second problem is
that it can cause lock order reversals due to parts of the VM still being
under Giant.
Fix the problem be allocating the full pool at driver attach, when it is
safe to do so.
1. CMSG_NXTHDR(mhdr, cmsg) is supposed to dereference cmsg and return
the next header in the chain. If cmsg is NULL it should return
the first header, behaving essentially like CMSG_FIRSTHDR().
2. inet6_rth_(space|init|add) should do basic checking on their input
to verify that the number of headers (segments) is
between 0 and 127 inclusive.

1. The static buffer that ping6(8) uses to hold the control data
it gets from recvmsg(2) is too small in some cases.
2. When it prints the extra header information it doesn't do
any checking to make sure the data it's printing is within
the bounds of the supplied buffer.
Fix this by:
o Increasing the buffer to hold extra headers to 10240 bytes (the minimum
according to RFC3542 sec. 20.1) and allocate it dynamically.
o In verbose mode, specify a warning if any control data from recvmsg(2)
was truncated because the buffer was too small.
o When printing the extra headers make sure not to overrun the buffer
boundaries.

o Fix node leakage in ural_start(), if ural_tx_mgt() fails.
o Fix mbuf leakage in ural_tx_{mgt,data}(), if usbd_transfer() fails.
o In ural_tx_{mgt,data}(), set ural_tx_data.{m,ni} to NULL, if
usbd_transfer() fails, so they will not be freed again in ural_stop().

Group mutexes used in hwpmc(4) into 3 "types" in the sense of
witness(4):
- leaf spin mutexes---only one of these should be held at a time,
so these mutexes are specified as belonging to a single witness
type "pmc-leaf".
- `struct pmc_owner' descriptors are protected by a spin mutex of
witness type "pmc-owner-proc". Since we call wakeup_one() while
holding these mutexes, the witness type of these mutexes needs
to dominate that of "sleepq chain" mutexes.
- logger threads use a sleep mutex, of type "pmc-sleep".

When nbytes=0, sendfile(2) should use file size. Because of the bug, it
was sending half of a file. The bug is that 'off' variable can't be used
for size calculation, because it changes inside the loop, so we should
use uap->offset instead.

The support for RFC 2640 (UTF8) is optional and rudimentary.
The server just advertises its capability to handle UTF-8 file
names and relies on its own 8-bit cleanness, as well as on
the backward compatibility of UTF-8 with ASCII. So uploaded
files will have UTF-8 names, but the initial server contents
should be prepared in UTF-8 by hand, no on-the-fly conversion
of file names will be done.
