Update for Zeek 2.6.x

[peasead]

Updated bzar_dce-rpc.bro and bzar_smb.bro re: #4

[petiepooo]

Thanks for submitting this PR, @peasead. I pulled your master branch in to test on my system, and I'm still getting this warning in stdout.log:

warning in /opt/bro/share/bro/policy/protocols/smb/load.bro, line 1: deprecated script loaded from /opt/bro/share/bro/bzar/./main.bro:10 "Use '@load base/protocols/smb' instead"

Making the change to bzar/main.bro as the warning suggests makes it go away and everything appears to still be working.

This does, of course, break compatibility with Bro 2.5.5... I don't think there's a way around that.

In terms of compatibility with older versions of Zeek...how about we make a branch to support 2.5 before merging?

[johnwunder]

Apparently @mfrndz discovered that you can use @if directive to target code at specific versions of Zeek. This would allow us to keep all code in the master branch and runnable across Zeek versions, so we'd like to go with that. @peasead thx for the PR...if you want to update it to do that go for it, otherwise I'll close this and we should be able to push something up in the next couple of days.

I threw up a separate shot at this here: #14. I think we want the @if directives in both the load and in the code itself. Please review and if it looks good I'll merge. Thanks for looking into this!

[peasead]

Looks good to me, @johnwunder. Sorry to give you extra work 😬

[johnwunder]

Great, and no problem, thanks for getting it started! I'll go ahead and merge #14.
