Move dpd.log to policy script
To address review feedback in GH-4362: rename analyzer-failed-log.zeek
to loggig.zeek, analyzer-debug-log.zeek to debug-logging.zeek and
dpd-log.zeek to deprecated-dpd-log.zeek.
Includes respective test, NEWS, etc updates.
The main part of this commit are changes in tests. A lot of the tests
that previously relied on analyzer.log or dpd.log now use the new
analyzer-failed.log.
I verified all the changes and, as far as I can tell, everything
behaves as it should. This includes the external test baselines.
This change also enables logging of file and packet analyzer to
analyzer_failed.log and fixes some small behavior issues.
The analyzer_failed event is no longer raised when the removal of an
analyzer is vetoed.
If an analyzer is no longer active when an analyzer violation is raised,
currently the analyzer_failed event is raised. This can, e.g., happen
when an analyzer error happens at the very end of the connection. This
makes the behavior more similar to what happened in the past, and also
intuitively seems to make sense.
A bug introduced in the failed service logging was fixed.

minor BTest maintenance updates for -O gen-C++
fix for more robustly finding BTests to assess for -O gen-C++
fix for -O gen-C++ dealing with type constants of unnamed compound types
This change adds two new hooks to the Intel framework that can be used
to intercept added and removed indicators and their type.
These hooks are fairly low-level. One immediate use-case is to count the
number of indicators loaded per Intel::Type and enable and disable the
corresponding event groups of the intel/seen scripts.
I attempted to gauge the overhead and while it's definitely there, loading
a file with ~500k DOMAIN entries takes somewhere around ~0.5 seconds hooks
when populated via the min_data_store store mechanism. While that
doesn't sound great, it actually takes the manager on my system 2.5
seconds to serialize and Cluster::publish() the min_data_store alone
and its doing that serially for every active worker. Mostly to say that
the bigger overhead in that area on the manager doing redundant work
per worker.

Redis seems to only want client data first to request server data. The
DPD signature seems to pick up on some cases where server data comes
first, but is otherwise "valid" RESP. See if this helps lower FP rates.

site/local: Switch to detect-sql-injection
Add a revised script for detecting HTTP SQL injection, deprecate original
In GH-4422 it was pointed out that the protocols/conn/failed-service-logging.zeek
policy script only works when
`DPD::track_removed_services_in_connection=T` is set.
This was caused by a logic error in the script. This commit fixes this
logic error and introduces an additional test that checks that
failed-service-logging works even when the option is not set to true.
Ensure the client side also uses the initial destination connection ID
for decryption purposes instead of the one from the current long header
packet. PCAP from local WiFi hotspot.
Instead of sending the accumulated CRYPTO frames after processing an
INITIAL packet, add logic to determine the total length of the TLS
Client or Server Hello (by peeking into the first 4 byte). Once all
CRYPTO frames have arrived, flush the reassembled data to the TLS
analyzer at once.
