* origin/topic/johanna/dtls:
a few more small script-level fixes
update test baselines
add a simple leak test for dtls
add signature for dtls client hello
Make the plugin structure more... legal.
Only force logging of SSL if it actually was the SSL analyzer that failed.
DTLS working.
Implement correct parsing of TLS record fragmentation.
Make handshake analyzer flow-based. This means we can feed data to it in chunks, which makes dealing with fragmentation a little bit more convenient.
When setting the SSL analyzer to fail, also stop processing data that already has been delivered to the analyzer, not just future data.
First step for a DTLS analyzer.

I added the $path to the create_stream() calls inside doc/ as well.

add a basic leak test for an unparseable enum
Change the way the input framework deals with values it cannot convert into BroVals (especially enums)
Make error message when encountering not existing enums better.
BIT-1199: #merged
into BroVals (especially enums)
Not we do not force an internal error anymore. Instead, we raise an
normal error and set an error flag that signals to the top-level
functions that the value could not be converted and should not be
propagated to the Bro core. This sadly makes the already messy code even
more messy - but since errors can happen in deeply nested data
structures, the alternative (catching the error at every possible
location and then trying to clean up there instead of recursively
deleting the data that cannot be used later) is much worse.
Addresses BIT-1199
This allows the path for the default filter to be specified explicitly
when creating a stream and reduces the need to rely on the default path
function to magically supply the path.
The default path function is now only used if, when a filter is added to
a stream, it has neither a path nor a path function already.
Adapted the existing Log::create_stream calls to explicitly specify a
path value.
Addresses BIT-1324
* origin/topic/johanna/cert-validation:
and still use the hash for notice suppression.
add knob to revert to old validation behavior
Update certificate validation script - new version will cache valid intermediate chains that it encounters on the wire and use those to try to validate chains that might be missing intermediate certificates.
BIT-1332 #merged
The only thing that is missing is a signature to detect the protocol (it
has no well-known port).
Reassembly is kind of fidgety - at the moment we only support
re-assembling one simultaneous message per direction (which looking at
our test-traffic might not be a problem). And I am not quite sure if I
got all cases correct...
But - it works :)
This commit mostly does a lot of refactoring of the current SSL
analyzer, which is split into several parts.
The handshake protocol is completely taken out of the SSL analyzer and
was refactored into its own analyzer (called tls-handshake-analyzer).
This will also (finally) make it possible to deal with TLS record
fragmentation.
Apart from that, the parts of the SSL analyzer that are common to DTLS
were split into their own pac files. Both the SSL analyzer and the (very
basic, mostly nonfunctional) DTLS analyzer use their own pac files and
those shared pac files.
All SSL tests still pass after refactoring so I hope I did not break
anything too badly.
At the moment, we have two different modules in one directory and I
guess the way I am doing this might be an abuse of the system. It seems
to work though...
intermediate chains that it encounters on the wire and use those to try
to validate chains that might be missing intermediate certificates.
This vastly improves the number of certificates that Bro can validate.
The only drawback is that now validation behavior is not entirely
predictable anymore - the certificate of a server can fail to validate
when Bro just started up (due to the intermediate missing), and succeed
later, when the intermediate can be found in the cache.
Has been tested on big-ish clusters and should not introduce any
performance problems.
For testing data store queries, when statements may not work well if
time stops advancing e.g. due to lack of input sources, so try to
workaround by reading a trace file in unit test.

Updating plugin.hooks baseline so that test succeeds
Revert spacing change that shouldn't have been included with the previous changeset ... should fix all of the plugin tests save hooks, which needs to be updated.
More small fixes
Small fixes
Incremental
Re-updating plugin.hooks test to include new argument output (after merge).
Fixing logic errors in HandlePluginResult
Updating tests and tweaking HookArgument to include Frame support.
Incremental commit: implementing a wrapper for the Val class.
Reverting change to const status of network_time. Also, see FIXME: in Func.cc / HandlePluginResult ...
Tweaks to result handling to make things a little more sane.
Plugin API: minor change (adding parent frame) to support calling methods from hook. Also declare network time update argument to be const because good practice.
