UniversalMachExcServer provided both an interface and an implementation,
contrary to the other classes in the exc_server_variants family. This
was mostly done for reasons of economy in an already-large class family.
Unfortunately, this decision meant that it was impossible for other code
to use UniversalMachExcServer, which required that CatchMachException()
be implemented, and also extend another class without violating the
style guide’s prohibition of multiple implementation inheritance. This
became a problem in a lot of test code, which extended MachMultiprocess
and UniversalMachExcServer.
UniversalMachExcServer is now given its own nested Interface class,
which is a pure interface. All users of UniversalMachExcServer are
changed from “is-a” UniversalMachExcServer to “has-a”
UniversalMachExcServer and “is-a” UniversalMachExcServer::Interface.

the child_port subsystem.
Common routines shared with the ExcServer family of classes have been
moved to a new file, where they can be shared between different
MachMessageServer::Interface implementations.

This change was generated mechanically by running:
find . \( -name \*.cc -or -name \*.mm -or -name \*.h \) \
-and -not -path ./third_party/\* -and -not -path ./out/\* \
-exec sed -i '' -E -e 's/(^|[^_])NULL/\1nullptr/g' {} +
Further manual fix-ups were applied to remove casts of nullptr to other
pointer types where possible, to preserve the intentional use of NULL
(as a short form of MACH_PORT_NULL) in exception_port_tool, and to fix
80-column violations.

mach_exception_data_type_t is more generic and is used for any element
of a codes[] array. For individual elements, the typedefs
mach_exception_code_t and mach_exception_subcode_t are available. Using
mach_exception_code_t when possible gives slightly more descriptive
code.
No functional change.

There’s no reason that “in” or “request” messages should be non-const.
This makes them const, bridges the const gap left by the MIG-generated
“check” functions with wrappers, and uses non-const fields in
“out” messages instead of const fields in “in” messages for in-out
parameters.
