We do this for DEBUG_SUBD already, but I wanted to debug the main lightningd.
(We rename --debugger to the more accurate --dev-debug-self)

During our development, we modified the way
we report backtraces.
On a minimal configuration in OpenBSD, it seems that we
no longer compile from commit a9f26b7d07 because
our conditional code is buggy.
With the following compiler
vultr# cc -v
OpenBSD clang version 13.0.0
Target: amd64-unknown-openbsd7.3
Thread model: posix
InstalledDir: /usr/bin
We have the following error
cc common/channel_id.c
cc common/daemon.c
common/daemon.c:218:2: error: implicit declaration of function 'add_steal_notifiers' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
add_steal_notifiers(NULL);

1 error generated.

Also requires us to expose memleak when !DEVELOPER, however we only
ever used the memleak tracking when the LIGHTNINGD_DEV_MEMLEAK
environment variable was set, so keep that.

We should actually be including this (as it may define _GNU_SOURCE
etc) before any system headers. But where we include <assert.h> we
often didn't, because check-includes would complain that the headers
included it too.
Weaken that check, and include config.h in C files before assert.h.

We force use of tal_wally_start/tal_wally_end around every wally
allocation, and with "end" make the caller choose where to reparent
everything.
This is particularly powerful where we allocate a tx or a psbt: we
want that tx or psbt to be the parent of the other allocations, so
this way we can reparent the tx or psbt, then reparent everything
else onto it.
Implementing psbt_finalize (which uses a behavior flag antipattern)
was tricky, so I ended up splitting that into 'psbt_finalize' and
'psbt_final_tx', which I think also makes the callers clearer.

Since we now over-write the wally malloc/free functions, we need to do
so for tests as well. Here we pull up all of the common setup/teardown
logic into a separate place, and update the tests that use libwally to
use the new common_setup core

Didn't generally fixup inside comments and the bech32 code: reformatting that
is just anti-social.

GCC 10 defaults to `-fno-common`. no longer automatically sharing
global variable definitions, which makes it important to define
them in only one place (otherwise there will be duplicate definition
errors). Add `extern` qualifiers where (I think) is the best place for
them.
According to the doc (https://download.libsodium.org/doc):
"sodium_init() initializes the library and should be called before
any other function provided by Sodium. [...]
the function ensures that the system's random number generator has
been properly seeded.".
Use the same "child of tal object" trick to mark things "notleak".
That simplifies things and means we don't have to track them being
reallocated.

This fixes block parsing on testnet; specifically, non-standard tx versions.
We hit a type bug in libwally (wallt_get_secp_context()) which I had to
work around for the moment, and the updated libsecp adds an optional hash
function arg to the ECDH function.

This currently just invokes GDB, but we could generalize it (though
pdb doesn't allow attaching to a running process, other python
debuggers seem to).

We probably also want to call secp_randomise/wally_secp_randomize here
too, and since these calls all call setup_tmpctx, it probably makes
sense to have a helper function to do all that. Until thats done, I
modified the tests so grepping will show the places where the sequence
of calls is repeated.

If you steal something onto its own child, you create a loop. These are
expensive to check for at runtime, but they can hide from memleak and are
usually a bad idea. So we add a tal_steal() notify which does this work
in DEVELOPER mdoe.

Code changes:
1. Expose daemon_poll() so lightningd can call it directly, which avoids us
having store a global and document it.
2. Remove the (undocumented, unused, forgotten) --rpc-file="" option to disable
JSON RPC.
3. Move the ickiness of finding the executable path into subd.c, so it doesn't
distract from lightningd.c overview.

In particular, the main daemon and subdaemons share the backtrace code,
with hooks for logging.
The daemon hook inserts the io_poll override, which means we no longer
need io_debug.[ch]. Though most daemons don't need it, they still link
against ccan/io, so it's harmess (suggested by @ZmnSCPxj).
This was tested manually to make sure we get backtraces still.
