This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
#239
* MySQL: the parser for this was generally broken (not following
the specification well) and needed many changes. One addition is a
new "mysql_result_row" event that provides access to the results of
queries.
* SMB: the spec seems to explitly call out the omission of the
PrimaryDomain field on SMB_COM_SESSION_SETUP_ANDX responses (and I
don't see that field in pcaps either), so this may have just been a
typo that used to work fine in the past only due to faulty array
parsing behavior in binpac.
