[HEADS UP] lockmgr needing of sys/lockmgr.h on thirdy part codes

[Attilio Rao]

Hello,
after MFC'ed the usage of LOCK_FILE and LOCK_LINE for lockmgr(9), now
thirdy part code needs to include sys/lock.h just priorior than
sys/lockmgr.
Even if the patch doesn't break ABI / KPI (so it doesn't need thirdy
part KLD to be recompiled), it worths noting that the new code needs
this extra-care in order to be fully compliant.

Thanks,
Attilio
