This class is a parameter of virtual methods of the Backend API for users
to implement and also a parameter to the HookPublishEvent() API. Seems it
shouldn't be in detail and instead we should own it.
Alternatively, could mark the cluster APIs as not-stable-yet, but I
think we can move forward and make it non-detail for 8.0.
Currently, plugins do not have a way to further inspect or even mutate
script functions after ZAM optimization ran. One use-case here is
zeek-perf-support [1]. This plugin wraps Stmt instances of functions,
events and hooks hooks with a small assembly stub to support JIT map
files [2] and for integration with perf tools.
This change introduces a new InitPreExecution() hook that runs after
ZAM optimization completed, just before the zeek_init() event is enqueued.
Additionally, remove the existing CPP_activation_hook. It doesn't seem
to be used. If it becomes necessary in the future, the new
InitPreExecution() hook can be leveraged instead.

This largely copies over Spicy's `.clang-format` configuration file. The
one place where we deviate is header include order since Zeek depends on
headers being included in a certain order.
When bumping the VERSION file, everything that includes the auto-generated
zeek/zeek-config.h needs to rebuild and ccache usage is voided due the file
changing. Split the mutable version information into a new zeek-version.h
file to avoid this.
Further, do not include zeek-version.h within Plugin.h and avoid the reference
to ZEEK_VERSION_FUNCTION unless we're building an external plugin.
Closes#2776.

The new hooks works similar to the existing `HookLoadFile` but,
additionally, allows the plugin to return a string that contains the
code to be used for the file being loaded. If the plugin does so, the
content of any actual file on disk will be ignored (in fact, there
doesn't even need to be a file on disk in that case). This works for
both Zeek scripts and signatures.
There's a new test that covers the new functionality, testing loading
both scripts and signatures from memory. I also manually tested that the
debugger integration works, but I don't see much of a way to add a
regression test for that part.
We keep the existing hook as well for backwards compatibility. We could
decide to deprecate it, but not sure that buys us much, so left that
out.
Closes#1757.
