Add NEWS about new features of broctl and upgrade info
Add more script package README files

The text from these README files appears on the "Bro Script Packages"
page after building the documentation.
Add gawk to list of optional packages

BSD and debian-based Linux do not include gawk by default.  Noticed
that a test was failing on these platforms due to the use of a bro-cut
option that requires gawk.
Hack to make sure that the starting BPF filter is logged on clusters.
Add UDP support to the checksum offload detection script.

Fix for input readers occasionally dead-locking.

Bernhard and I tracked it down we believe: the thread queue could
deadlock in certain cases. As a fix we tuned the heuristic for telling
if a queue might have input to occasionaly err on the safe side by
flagging "yes", so that processing will proceed.

It's a bit unfortunate to apply this fix last minute before the
release as it could potentially impact performance if the heuristic
fails to often. We believe the chosen parmaterization should be fine ...
alternative deadlock issue fix.

This fix also fixes the deadlock issue without putting any
new strain into the main packet processing path.

Instead of occasionally returning true in MaybeReady sometime,
we occasionally process threads if time_mgr time is not running.

If time_mgr time is running, we have heartbeat messages that will
trigger processing in any case -- processing always checks the
exact state of the Queues.

This fix probably also means that we can remove the communication
loads from all input framework tests and run them all simultaneously.
