malloc(9) flags within sys.

Exceptions:

- sys/contrib not touched
- sys/mbuf.h edited manually

Node constructor methods are supposed to be called in syscall
context always. Convert nodes to consistently use M_WAITOK flag
for memory allocation.

Fix dangling callout problem in the Bluetooth L2CAP code that leads to
panic. The panic happens when outgoing L2CAP connection descriptor is
deleted with the L2CAP command(s) pending in the queue. In this case when
the last L2CAP command is deleted (due to cleanup) and reference counter
for the L2CAP connection goes down to zero the auto disconnect timeout
is incorrectly set. pjd gets credit for tracking this down and committing
bandaid.
