It always called MH_ALIGN for small lengths being
prepended (less than MHLEN). This meant that if you did
a prepend on a non M_PKTHDR the system would panic with
the KASSERT in MH_ALIGN. Instead we are not aware of
this and do a MH_ALIGN or M_ALIGN as appropriate.

protecting ifnet labels, so copying from the ifnet copy could result in
an inconsistent version being copied out.

- Move linux_nanosleep() from src/sys/amd64/linux32/linux32_machdep.c to
src/sys/compat/linux/linux_time.c.
- Validate timespec ranges before use as Linux kernel does.
- Fix l_timespec structure.
- Clean up style(9) nits.
Add rudimentary IPC_INFO/MSG_INFO command support for linux_msgctl()
to pacify Linux ipcs(1). While I am here, add more bound checks
for linux_msgsnd() and linux_msgrcv().
copyin()/copyout() for message type is separated from msgsnd()/msgrcv() and
it is done from its wrapper functions to support 32-bit emulations. After I
implemented this, I have briefly referenced NetBSD and Darwin. NetBSD passes
copyin()/copyout() function pointers from wrappers. Darwin passes size of
message type as an argument, which is actually similar to my first
implementation (P4 109706). We may revisit these implementations later.
would be able to work with aac(4).
This approach is used by some other drivers as well. However, we
need a more generic way to do this in order to avoid having to
special case headers in individual drivers for each platform.

been handled instead of when at least one descriptor was just handled.
For bge, it is normal to get a txeof when only a small fraction of the
queued tx descriptors have been handled, so the bug broke the watchdog
in a usual case.
