f5a689a760 Switch the MIME fields in smtp.log back to showing what's actually given.
- SMTP protocol headers now do some minimal parsing to clean up
   email addresses.
 - New function named split_mime_email_addresses to take MIME headers
   and get addresses split apart but including the display name.
 - Update tests.

85220e46aa Weird: fix potential small issue when ignoring duplicates
In all versions so far, the identifier string that was used for
comparisons might have been different from the identifier string that
was added (when certain notices are used).

697b2748f5 Rewrite weird logging.
This commit rewrites the way that weirds are logged and fixes a number
of issues on the way. Most prominently, flow weirds now actually log
information about the flow that they occur in (before this change, they
only logged the name of the weird, which is only marginally helpful).

Besides restructuring how weird logging works internally, weirds can now
also be generated by calling Weird::weird with the info record directly,
allowing more fine-granular passing of information. This is e.g. used
for DNS weirds, which do not have the connection record available any
more when they are generated (before data like the connection ID was
just not logged in these instances).

d89ee3cee0 Change the meaning of some email fields.
We now extract email addresses in the fields that one would expect
to contain addresses.  This makes further downstream processing of
these fields easier like log analysis or using these fields in the
Intel framework.  The primary downside is that any other content
in these fields is no longer available such as full name and any
group information.  I believe the simplification of the content in
these fields is worth the change.

Added "cc" to the script that feeds information from SMTP into the
Intel framework.

A new script for email handling utility functions has been created
as a side effect of these changes.

7c2307e079 Move the HTTP "filename" field to "orig_filenames" and "resp_filenames"
This changes the HTTP log format slightly but shouldn't mess
up anything that anyone was doing because the old "filename"
field was never actually filled out.  Tests are updated as well.

8a87055fcc Fixed table expiration evaluation.
The expiration attribute expression is now evaluated for every use. Thus
later adjustments of the value (e.g. by redefining a const) will now
take effect. Values less than 0 will disable expiration.

Added a new BIF haversine_distance that computes distance between two

Added a new Bro script function haversine_distance_ip that does the same
but takes two IP addresses instead of latitude/longitude.  This function
requires that Bro be built with libgeoip.

This commit rewrites catch and release, fixing issues with it and making
it fully cluster capable. A dedicated netcontrol_catch_release.log is
also added.

This is not quite done yet; a few more log messages are missing. There
should hopefully not be many big issues left.

4f9cb6912a Fix for a table refering to a expire function that's not defined.
I was hoping to report this right at startup through a static check
but turns out we don't have the right machinery in place for that.
That would need to be done after the AST has been finalized, but our
AST traversal code can't iterate over types. So instead I've changed
this so that it's still being reported at runtime but at least
doesn't crash Bro anymore.

Closes BIT-1597.

a4e5591e18 Fix some failing plugin tests on OS X 10.11
By default, OS X 10.11 does not include openssl headers.
Since building a Bro plugin #includes Bro headers, which #include openssl
headers, we need to tell cmake to find these so that the compiler
can use them.
