I did a brief audit of tmpctx uses, and we do leak them in various
corner cases. Fortunely, all our daemons are based on some kind of
I/O loop, so it's fairly easy to clean a global tmpctx at that point.
This makes things a bit neater, and slightly more efficient, but also
clearer: I avoided creating a tmpctx in a few places because I didn't
want to add another allocation. With that penalty removed, I can use
it more freely and hopefully write clearer code.

We didn't get the entire thing in the parent when gossipd crashed: stderr
is suitable for these I think.

Our handling of SIGPIPE was incoherent and inconsistent, and we had much
cut & paste between the daemons. They should *ALL* ignore SIGPIPE, and
much of the rest of the boilerplate can be shared, so should be.

This is a bit messier than I'd like, but we want to clearly remove all
dev code (not just have it uncalled), so we remove fields and functions
altogether rather than stub them out. This means we put #ifdefs in callers
in some places, but at least it's explicit.
We still run tests, but only a subset, and we run with NO_VALGRIND under
Travis to avoid increasing test times too much.

We use a file descriptor, so when we consume an entry, we move past it
(and everyone shares a file offset, so this works).
The file contains packet names prefixed by - (treat fd as closed when
we try to write this packet), + (write the packet then ensure the file
descriptor fails), or @ ("lose" the packet then ensure the file
descriptor fails).
The sync and async peer-write functions hook this in automatically.

Or for blackbox tests --gdb1=<subdaemon> / --gdb2=<subdaemon>.
This makes the subdaemon wait as soon as it's execed, so we can attach
the debugger.
