This also changes the argument type of Func::operator() to zeek::Args*
to allow plugins to be able to alter function arguments in place as
was previously documented.
The reason behind this one is that without a real variable name, the profile objects are immediately desctructed and the profiling only happens for the small window when they were valid. If the intention is to profile the method where they were defined, this doesn't actually happen.
Only 1% build time speedup, but still, it declutters the headers a bit.

The Zeek code base has very inconsistent #includes. Many sources
included a few headers, and those headers included other headers, and
in the end, nearly everything is included everywhere, so missing
#includes were never noticed. Another side effect was a lot of header
bloat which slows down the build.
First step to fix it: in each source file, its own header should be
included first to verify that each header's includes are correct, and
none is missing.
After adding the missing #includes, I replaced lots of #includes
inside headers with class forward declarations. In most headers,
object pointers are never referenced, so declaring the function
prototypes with forward-declared classes is just fine.
This patch speeds up the build by 19%, because each compilation unit
gets smaller. Here are the "time" numbers for a fresh build (with a
warm page cache but without ccache):

- Adds new trigger namespace
- Adds trigger::Manager class as a new IOSource for keeping track of triggers and integrating them into the loop. Previously the loop relied on the event manager Drain() method to process all triggers on every loop, but now that the loop actively waits for events to occur, triggers would not fire when they needed to. Adding them as part of the loop ensures they're checked.
* origin/topic/robin/gh-239:
Undo a change to btest.cfg from a recent commit
Updating submodule.
Fix zeek-wrapper
Update for renaming BroControl to ZeekControl.
Updating submodule.
GH-239: Rename bro to zeek, bro-config to zeek-config, and bro-path-dev to zeek-path-dev.
Note - this compiles, but you cannot run Bro anymore - it crashes
immediately with a 0-pointer access. The reason behind it is that the
required clone functionality does not work anymore.
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
Added ConnectionEventFast() and QueueEventFast() methods to avoid
redundant event handler existence checks.
It's common practice for caller to already check for event handler
existence before doing all the work of constructing the arguments, so
it's desirable to not have to check for existence again.
E.g. going through ConnectionEvent() means 3 existence checks:
one you do yourself before calling it, one in ConnectionEvent(), and then
another in QueueEvent().
The existence check itself can be more than a few operations sometimes
as it needs to check a few flags that determine if it's enabled, has
a local body, or has any remote receivers in the old comm. system or
has been flagged as something to publish in the new comm. system.
Majority of PLists are now created as automatic/stack objects,
rather than on heap and initialized either with the known-capacity
reserved upfront or directly from an initializer_list (so there's no
wasted slack in the memory that gets allocated for lists containing
a fixed/known number of elements).
Added versions of the ConnectionEvent/QueueEvent methods that take
a val_list by value.
Added a move ctor/assign-operator to Plists to allow passing them
around without having to copy the underlying array of pointers.
