User misconfiguration may lead to routing loops where we try to send the tunnel
packet into the tunnel. This eventually leads to stack overflows and panics.
Avoid this using if_tunnel_check_nesting(), which will drop the packet if we're
looping or we hit three layers of nested tunnels.

In the future, we will Default to _FORTIFY_SOURCE=2 if SSP is enabled,
otherwise default to _FORTIFY_SOURCE=0. For now we default it to 0
unconditionally to ease bisect across older versions without the new

Notably:
- libc needs to #undef some of the macros from ssp/* for underlying
implementations
- ssp/* wants a __RENAME() macro (snatched more or less from NetBSD)
There's some extra hinkiness included for read(), since libc spells it
as "_read" while the rest of the world spells it "read."

Cast the time type to (long). This is correct on all architectures. On
i386, this promotes the int time_t to a long (which is also 32-bit). On
64-bit architectures, this promotes the 64-bit signed time_t to a 64-bit
signed int type.

In some cases, the USB_QUIRK_VP macro was being misused. Instead of
setting quirks to the intended value, the first two supplied quirks
would go into lo_rev and hi_rev. Replace it with USB_QUIRK_VO which only
takes the needed args. This also makes the Dummy products, which where
being used to correctly set vendor only quirks, not necessary.

Consistently use the weird ssize_t type for things I know are unsigned,

GCC 13 complains that we might be writing too much to an on-stack buffer
when createing a filename.
In practice there is a check that filename isn't too long given the
time format and other static characters so GCC is incorrect, but GCC
isn't wrong that we're potentially trying to put a MAXPATHLEN length
string + some other characters into a MAXPATHLEN buffer (if you ignore
the check GCC can't realistically evaluate at compile time).
Switch to snprintf to populate filename to ensure that future logic
errors don't result in a stack overflow.
Shorten the questionably named yyyymmdd buffer enough to slience the
warning (checking the snprintf return value isn't sufficent) while
preserving maximum flexibility for admins who use the -F option.
