This driver also sleeps in its if_init routine, so it likely doesn't really

dispatched without Giant, and add NETISR_FORCEQUEUE, which allows specific
netisr handlers to always be dispatched via a queue (deferred). Mark the
usb and if_ppp netisr handlers as NETISR_FORCEQUEUE, and explicitly
acquire Giant in those handlers.
Previously, any netisr handler not marked NETISR_MPSAFE would necessarily
run deferred and with Giant acquired. This change removes Giant
scaffolding from the netisr infrastructure, but NETISR_FORCEQUEUE allows
non-MPSAFE handlers to continue to force deferred dispatch so as to avoid
lock order reversals between their acqusition of Giant and any calling
context.
It is likely we will be able to remove NETISR_FORCEQUEUE once
IFF_NEEDSGIANT is removed, as non-MPSAFE usb and if_ppp drivers will no
longer be supported.

soun->sun_path isn't a null-terminated string. As UNIX(4) states, "the
terminating NUL is not part of the address." Since strlcpy has to return
"the total length of the string [it] tried to create," it walks off the end
of soun->sun_path looking for a \0.

I wrote these to test amd64 asm functions that used
maxss, maxsd, minss, and minsd, but it turns out that
those instructions don't handle NaNs and signed zero
in the same way as fmin() and fmax() are required to,
so we're stuck with the C versions for now.

- initializing a disk without MBR bogusly emits the error:
fdisk: invalid fdisk partition table found
- initializing a disk with or without MBR bogusly emits either:

- the default geometry for non-ATA and non-SCSI disks is either
invalid or sub-optimizal.
