0b8535b879 Merge remote-tracking branch 'origin/topic/vlad/gh-1286'
Merge adjustments:
- Rewrote the check for error response as a switch statement to
  fix compiler warning about signed/unsigned comparison and also
  to just simplify/clarify the logic.
- Changed the btest to use `zeek -b`.

* origin/topic/vlad/gh-1286:
  Add tests for new SMB3 multichannel support

17cd740519 Update btest-diff calls on binary files to using "--binary"
This converts Johanna's TEST_DIFF_CANONIFIER removals via "env -u" to
using the new "btest-diff --binary", and updates the affected baselines.

442cb40db8 Fix binary baseline & line-end problem
By default all baslines are run through diff-remove-timestamp. On a BSD
sed implementation, this means that a newline is added to the end of the
file, if no newline was there originally. This behavior differs from GNU
sed, which does not add a newline.

In this commit we unify this behavior by always adding a newline, even
when using GNU sed. This commit also disables the canonifier for a bunch
of binary baselines, so we do not have to change them.

c0bd02e18f Canonifier improvements for the scripts.base.frameworks.logging.ascii-double test
This now more surgically applies canonifiers so that the double-format
numerical output isn't itself canonified.

01ec5ebdcd Reverts the regex change in dead3226a5.
The regex change broke some of the external tests. I added some more cases
to the regular email btest to hopefully cover all of the cases better.

7362f30c3a Sumstats: allow users to manage epoch manually
This change allows users to specify an epoch length of 0, which means
that the user manually has to finish the epochs. A new next_epoch
function is introduced to allow users to manually end epochs.

3769ed6c66 [SSH] Handle SSH version 1.99
SSH can set in its identification a version 1.99 (SSH-1.99-xxx).
That means the client/server is compatible with SSHv1 and SSHv2.
So the version choice depends of the both side.

1.99 : 1.99 => 2.0
1.99 : 1.x  => 1.x
1.99 : 2.0  => 2.O

(see "Compatibility With Old SSH Versions" in RFC 4253)

  Fix type clash fatal error with log filters that use $ext_func and $include/$exclude

f97a33e14d Fix type clash fatal error with log filters that use $ext_func and $include/$exclude
The logging manager's Manager::TraverseRecord(), called when adding a
log filter to a stream, skipped any fields intoduced by a filter's
$ext_func when such fields weren't mentioned in a $include restriction
or mentioned in an $exclude restriction. This was inconsistent with
Manager::RecordToFilterVals, used when actually writing log entries,
which does include those values.

The result was that the record indices descent in Manager::RecordToFilterVals
expects to find only record values, when in fact only the record
provided by ext_func is present. This leads to type mismatches and
hard Zeek exits like this one:

1300475173.475401 fatal error in zeek/share/zeek//base/init-bare.zeek, line 4810: Val::CONVERTER (string/record) (zeek)

The fix makes ext_func's field additions decisive, meaning the
filter's include/exclude lists don't apply to it. If a user really
wants to override this, they can reset the filter's ext_func back to
our no-op default.

The included btest produces the above error when the fix is not present.

b7bd87d9cf GH-1252: rename files with colons for Windows compatibility
A short-term measure so that the Zeek source tree can simply exist on a
Windows filesystem.  For true support, the logic that decides/generates
the filename format will need to change.

a16bd47bf7 GH-1164: Fix incorrect RSTOS0 conn_state determinations
The RSTOS0 `conn_state` label is documented as "Originator sent a SYN
followed by a RST, never saw SYN-ACK from responder", but was previously
applied to cases where no originator SYN exists, like a single RST-only
packet.

05cf511f18 GH-1119: add base/protcols/conn/removal-hooks.zeek
This adds two new functions: `Conn::register_removal_hook()` and
`Conn::unregister_removal_hook()` for registering a hook function to be
called back during `connection_state_remove`.  The benefit of using hook
callback approach is better scalability: the overhead of unrelated
protocols having to dispatch no-op `connection_state_remove` handlers is
avoided.

0af57d12b2 Change HTTP's DPD signatures so that each side can trigger the analyzer on its own.
This is to avoid missing large sessions where a single side exceeds
the DPD buffer size. It comes with the trade-off that now the analyzer
can be triggered by anybody controlling one of the endpoints (instead
of both).

Test suite changes are minor, and nothing in "external".

Closes #343.
