ZAM's implementation deviates from Zeek's in consideration of remappings, which
means that running ZAM produced conn.log service names prefixed with "spicy_"
whereas regular Zeek doesn't.
Rebuilding ZBody.cc is annoyingly slow with UBSAN or ASAN enabled. A rebuild
is currently triggered when touching Manager.h files like logging/Manager.h,
broker/Manager.h or file_analysis/Manager.h and various other headers that are
included from there or directly in ZBody.h.
Add tiny wrapper functions to Support.h that encapsulate the actual Zeek
functionality and move the includes to Support.cc instead. This will
cause frequent Support.cc rebuilds, but that is decently fast.
This comes at the expense of one indirect function call for some ops, but
its overhead should be negligible in comparison to a lookup for a
connection or component or a log_mgr->Write() call.
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.
