Technically, true, but we save more memory by sharing the prefix pointer
than we lose by leaking it.
However, we'd ideally refcount so it's freed if the log is freed and
all the entries using it are pruned from the log book.

We use the tal notifiers to attach a `backtrace` object on every
allocation.
This also means moving backtrace_state from log.c into lightningd.c, so
we can hand it to memleak_init().

It crashes under valgrind, causing a valgrind error: valgrind gives us a
backtrace anyway, so we don't need it.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

We used level -1 to mean "append to log", but that doesn't actually
work, and results in an assert if we try to prune the logs:
lightningd: daemon/pseudorand.c:36: pseudorand: Assertion `max' failed.
Expose logv_add and use that.

This is needed for the new testing framework since we wait for
messages to be printed on stdout. Buffering delays this
arbitrarily. Flushing so often should not have much of a performance
impact.
Before we had a global secp256k1_ctx we needed to hold this to print
out pubkeys, now it's completely orthogonal.

We don't need it for testing at the moment, and if we do it'll have
to change to relative anyway now we're going to use time_mono().

We had enum channel_side (OURS, THEIRS) for which end of a channel we
had, and htlc_side (LOCAL, REMOTE) for who proposed the HTLC.
Combine these both into simply "enum side".

The most complex thing we've logged yet, so we extract the core of the
log_struct_ function to call it multiple times.

Uses a gcc extension (cast to union) for typechecking, but that can be
removed for compilers which don't support it.
