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.
This has been around since Zeek v4.1, so it was warned about in Zeek 5.0
LTS and we could've removed it with 5.1.
Also removed merge_top_scope() from the zeek::detail namespace, it's
unused now.
Updated the when-aggregates test somehow. I'm not quite sure what had
been tested there :-/
* Rename overly generic ACCESSORS macro with ZEEK_ prefix
* A few places where whitespace was noticeably wrong/distracting
* Minor/obvious reference/move semantics improvements suggested by linter
* Remove unused detail::Scope::Remove(), no need for deprecation
- Add deprecated version of ID::SetType() that takes Type*
- Add deprecated versions of zeek::set_location in the global namespace
- Fix global namespace version of lookup_ID to return ID*
Merge adjustments:
- Preserved original `base_type_no_ref` argument type as ::TypeTag
- Removed superfluous #pragma guard around deprecated TableVal ctor
- Clarify NEWS regarding MetaHook{Pre,Post} deprecations
- Simplify some `::zeek::` qualifications to just `zeek::`
- Prefixed FORWARD_DECLARE_NAMESPACED macro with ZEEK_

Only one instance of base_type() getting a NewRef instead of AdoptRef
fixed in merge. All other changes are superficial formatting and
factoring.

Make sure unused scopes are freed to fix memory leaks.
The comment inside pop_scope() is now obsolete and I deleted it,
because this commit implements the real solution.
Note that this requires us to add a reference to the
push_existing_scope() call in dbg_eval_expr(), because it never owned
the reference.
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):
