ab6ddc7a33 practracker: split shutdown code out of main.c 
This is necessary to get the number of includes in main.c back under
control.  (In the future, we could just use the subsystem manager for
this kind of stuff.)

beedadbeac Try a different approach to making publish function seem used. 
We want the DISPATCH_ADD_PUB() macro to count as making a
DECLARE_PUBLISH() invocation "used", so let's try a new approach
that preserves that idea.  The old one apparently did not work for
some versions of osx clang.

bdeaf7d4b2 Code to manage publish/subscribe setup via subsystem interface. 
This commit has the necessary logic to run the publish/subscribe
system from the mainloop, and to initialize it on startup and tear
it down later.

a7681525ab Add function to clear publish bindings. 
When we clean up, we'd like to clear all the bindings that refer to
a dispatch_t, so that they don't have dangling pointers to it.

271a671822 pubsub: relationship checking functionality 
This code tries to prevent a large number of possible errors by
enforcing different restrictions on the messages that different
modules publish and subscribe to.

Some of these rules are probably too strict, and some too lax: we
should feel free to change them as needed as we move forward and
learn more.

9e60482b80 Pubsub: an OO layer on top of lib/dispatch 
This "publish/subscribe" layer sits on top of lib/dispatch, and
tries to provide more type-safety and cross-checking for the
lower-level layer.

Even with this commit, we're still not done: more checking will come
in the next commit, and a set of usability/typesafety macros will
come after.

e4d3098d4d Low-level dispatch module for publish-subscribe mechanism 
This module implements a way to send messages from one module to
another, with associated data types.  It does not yet do anything to
ensure that messages are correct, that types match, or that other
forms of consistency are preserved.

a62ac17198 Add a new inline function to check whether debug logging is on 
We already do this in our log_debug() macro, but there are times
when we'd like to avoid allocating or precomputing something that we
are only going to log if debugging is on.

df1a8a657e Actually close the stdout pipe on error in process_unix_exec 
When cleaning up after an error in process_unix_exec, the stdin
pipe was being double closed instead of closing both the stdin
and stdout pipes.  This occurred in two places.

d82a8a7f9d Add some more type checking. 
NOTE: This commit breaks the build, because there was a mistake in an
earlier change of exactly the sort that this is meant to detect!  I'm
leaving it broken for illustration.
