Fixes:
- Identifiers starting with _ are prohibited
- Some driveby header dependency cleaning which wound up with doing some
extra fixups.
- Fucking C style casts, man. C++ made these 1000% worse by letting you
also do memory corruption with them with references.
- Remove casts to Expr * where ExprBlackHole is an incomplete type by
introducing an explicitly-cast eBlackHoleAddr as Expr *.
- An incredibly illegal cast of the text bytes of the StorePath hash
into a size_t directly. You can't DO THAT.
Replaced with actually parsing the hash so we get 100% of the bits
being entropy, then memcpying the start of the hash. If this shows
up in a profile we should just make the hash parser faster with a
lookup table or something sensible like that.
- This horrendous bit of UB which I thankfully slapped a deprecation
warning on, built, and it didn't trigger anywhere so it was dead
code and I just deleted it. But holy crap you *cannot* do that.
inline void mkString(const Symbol & s)
{
mkString(((const std::string &) s).c_str());
}
- Some wrong lints. Lots of wrong macro lints, one wrong
suspicious-sizeof lint triggered by the template being instantiated
with only pointers, but the calculation being correct for both
pointers and not-pointers.
- Exceptions in destructors strike again. I tried to catch the
exceptions that might actually happen rather than all the exceptions
imaginable. We can let the runtime hard-kill it on other exceptions
imo.

we no longer need these since we're no longer using sinks to serialize things.

this is cursed. deeply and profoundly cursed. under NO CIRCUMSTANCES
must protocol serializer helpers be applied to temporaries! doing so
will inevitably cause dangling references and cause the entire thing
to crash. we need to do this even so to get rid of boost coroutines,
and likewise to encapsulate the serializers we suffer today at least
a little bit to allow a gradual migration to an actual IPC protocol.
(this isn't a problem that's unique to generators. c++ coroutines in
general cannot safely take references to arbitrary temporaries since
c++ does not have a lifetime system that can make this safe. -sigh-)

Pass this around instead of `Source &` and `Sink &` directly. This will
give us something to put the protocol version on once the time comes.
To do this ergonomically, we need to expose `RemoteStore::Connection`,
so do that too. Give it some more API docs while we are at it.

See API docs on that struct for why. The pasing as as template argument
doesn't yet happen in that commit, but will instead happen in later
commit.
Also make `WorkerOp` (now `Op`) and enum struct. This led us to catch
that two operations were not handled!

This is generally a fine practice: Putting implementations in headers
makes them harder to read and slows compilation. Unfortunately it is
necessary for templates, but we can ameliorate that by putting them in a
separate header. Only files which need to instantiate those templates
will need to include the header with the implementation; the rest can
just include the declaration.
This is now documenting in the contributing guide.
Also, it just happens that these polymorphic serializers are the
protocol agnostic ones. (Worker and serve protocol have the same logic
for these container types.) This means by doing this general template
cleanup, we are also getting a head start on better indicating which
code is protocol-specific and which code is shared between protocols.
