The hook being added is:
bool HookReporter(const std::string& prefix, const EventHandlerPtr event,
const Connection* conn, const val_list* addl, bool location,
const Location* location1, const Location* location2,
bool time, const std::string& buffer) override;
This hook gives access to basically all information that is available in
the function in Reporter.cc that performs the logging. The hook is
called each time when anything passes through the reporter in the cases
in which an event usually would be called. This includes weirds. The
hook can return false to prevent the normal reporter events from being
raised.
This commit fixes and extends the behavior of HookLoadFile. Before this
change, HookLoadFile appended ".bro" to each path that was @loaded, even
if the path specified directory names. Furthermore it only gave the path
of the file as it was specified in the Bro script without revealing the
final path of the file that it was going to load.
This patch changes this behavior - in addition to giving the unmodified
path given in the @load command, the hook now returns the resolved path
of the file or directory it is going to load (if found). The hook is
furthermore raises for @load-sigs and @load-plugin; a enum specifies the
kind of load that is happening.
The two hooks being added are:
void HookLogInit(const std::string& writer, const std::string& instantiating_filter, bool local, bool remote, const logging::WriterBackend::WriterInfo& info, int num_fields, const threading::Field* const* fields);
which is called when a writer is being instantiated and contains
information about the fields being logged, as well as
bool HookLogWrite(const std::string& writer, const std::string& filter, const logging::WriterBackend::WriterInfo& info, int num_fields, const threading::Field* const* fields, threading::Value** vals);
which is called for each log line being written by each writer. It
contains all the data being written. The data can be changed in the
function call and lines can be prevented from being written.
This commit also fixes a few small problems with plugin hooks itself,
and extends the tests that were already there, besides introducing tests
for the added functionality.
versions.bro uses the changing version string, which leads to changing
lines in the output of the hooks plugin, which is difficult to filter.
Hence, let's just @unload it, before it is being used.
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.
That way it can be reused more easily. This also avoid having to
change the serialization structure for packets, which is a problem as
external sources of packets (via Broccoli) wouldn't have the new
attributes available to send.
Also moving Packet.{h,cc} and Layer2.{h,cc} into iosource/, and
removing header size from properties that packet sources have to
provide, as we can now compute that easily from the link type.
Plus some more cleanup.

Updating plugin.hooks baseline so that test succeeds
Revert spacing change that shouldn't have been included with the previous changeset ... should fix all of the plugin tests save hooks, which needs to be updated.
More small fixes
Small fixes
Incremental
Re-updating plugin.hooks test to include new argument output (after merge).
Fixing logic errors in HandlePluginResult
Updating tests and tweaking HookArgument to include Frame support.
Incremental commit: implementing a wrapper for the Val class.
Reverting change to const status of network_time. Also, see FIXME: in Func.cc / HandlePluginResult ...
Tweaks to result handling to make things a little more sane.
Plugin API: minor change (adding parent frame) to support calling methods from hook. Also declare network time update argument to be const because good practice.

Conflicts:
testing/btest/Baseline/plugins.hooks/output
The init-plugin scripts now expects a destination directory. Normally
that would be a new subdirectory, but for the tests to keep working we
can also put it right into the current directory.
* Add frame support to HookArgument, since it's a new argument to HookCallFunction
* Fix test in api-version-mismatch to remove absolute paths from output
* Update test plugin to use new HookCallFunction interface
that init-plugin now generates.
Also adding new test that makes sure the the skeleton created by
init-plugin compiles on its own withoyt any further changes.
