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.

7040e30431 Fix diff-remove-abspath on OSX
\t does not work on OS-X and just matches the letter t. This commit
replaces it with a literal tab instead.

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.

3984d99a86 Make diff-remove-abspath canonifier match on non-whitespace paths only
This avoids swallowing multiple separate paths separated by unrelated
content into one substitution, like here:

orig_p=59856<...>/tcp] -> orig_p=59856/tcp, resp_h=192.150.187.43, resp_p=80/tcp]

3ca804421e Harden diff-remove-timestamps canonifier
This pattern got mislead by matching suffixes of other numbers, and
noramlizing exact 0-timestamps isn't really required.

- Remove eplicit "0.000000" number pattern from timestamp normalization

- Require beginning of line or non-numeric character before the
  beginning of the number replacement

Also now uses CMake's ENABLE_EXPORTS target property for the zeek

3.4, the policy was to export symbols by default for certain platforms,
but later versions need either the explicit target property or policy.

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

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.
