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.
Minor formatting change in merge so [[noreturn]] is consistently
on same line as function declarations.
* 'noreturn' of https://github.com/MaxKellermann/zeek:
threading/MsgThread: add [[noreturn]] to InternalError()
Flare: add [[noreturn]] to bad_pipe_op()
Obj: add [[noreturn]] attributes to Internal(), bad_ref()
Reporter: add [[noreturn]] attribute to several methods
The full process hierarchy isn't set up yet, but these changes
help prepare by doing two things:
- Add a -j option to enable supervisor-mode. Currently, just a single
"stem" process gets forked early on to be used as the basis for
further forking into real cluster nodes.
- Separates the parsing of command-line options from their consumption.
i.e. need to parse whether we're in -j supervisor-mode before
modifying any global state since that would taint the "stem" process.
The new intermediate structure containing the parsed options may
also serve as a way to pass configuration info from "stem" to its
descendent cluster node processes.
