* origin/topic/timw/776-using-statements:
Remove 'using namespace std' from SerialTypes.h
Remove other using statements from headers
GH-776: Remove using statements added by PR 770
Includes small fixes in files that changed since the merge request was
made.
Also includes a few small indentation fixes.
This unfortunately cuases a ton of flow-down changes because a lot of other
code was depending on that definition existing. This has a fairly large chance
to break builds of external plugins, considering how many internal ones it broke.
Those functions don't have a well-defined reference passing API, and
we had lots of memory leaks here. By using IntrusivePtr, reference
ownership is well-defined.
Use class IntrusivePtr<>.
This reference is necessary because add_type() may discard the
reference and hold only a reference to a clone of our EnumType.
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):

* All "Broxygen" usages have been replaced in
code, documentation, filenames, etc.
* Sphinx roles/directives like ":bro:see" are now ":zeek:see"
* The "--broxygen" command-line option is now "--zeexygen"
While scripts are parsed, a warning is raised for each usage of an
identifier marked as &deprecated. This also works for BIFs.
Addresses BIT-924, BIT-757.
- Move more functionality into base class.
- Remove cctors and assignment operators (weren't actually needed anymore)
- Switch from const char* to std::string.
This is essentially the code from the dynamic-plugin branch except for
some pieces that I have split out into separate, earlier commits.
I'm going to updatre things in this branch going forward.
Replaced some with InternalWarning or InternalAnalyzerError, the later
being a new method which signals the analyzer to not process further
input. Some usages I just removed if they didn't make sense or clearly
couldn't happen. Also did some minor refactors of related code while
reviewing/exploring ways to get rid of InternalError usages.
Also, for TCP content file write failures there's a new event:
"contents_file_write_failure".
Doesn't generate any docs, but it's hooked in to all places needed to
gather the necessary stuff w/ significantly less coupling than before.
The gathering now always occurs unconditionally to make documentation
available at runtime and a command line switch (-X) only toggles whether
to output docs to disk (reST format).
Should also improve the treatment of type name aliasing which wasn't a
big problem in practice before, but I think it's more correct now:
there's now a distinct BroType for each alias, but extensible types
(record/enum) will automatically update the types for aliases on redef.
Other misc refactoring of note:
- Removed a redundant/unused way of declaring event types.
- Changed type serialization format/process to preserve type name
information and remove compatibility code (since broccoli will
have be updated anyway).
Made some class templates for code that seemed duplicated between
file/protocol tags and managers. Seems like it helps a bit and
hopefully can be also be used to transition other things that have
enum value "tags" (e.g. logging writers, input readers) to the
plugin system.
