Rusty Russell 06a54606a3 check-includes: allow redundant "config.h"
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.

Rusty Russell d5cb0d85b5 utils: use a cleaner pattern to capture wally allocations.
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.

niftynei fbe50e087a setup: create a common setup which will handle the wally-context
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

Wladimir J. van der Laan e4c6fd89b7 Add missing `extern` qualifiers for gcc 10
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.

darosior fe2543d8dc daemons: initialize libsodium at setup
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.".

Rusty Russell 2652cc9704 common/memleak: simplify notleak() handling.
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.

Rusty Russell e0ec9ac521 libwally: update to 0.6.8.
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.

Fixes: #2563

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).

Jon Griffiths 087ef43a0d Call wally_init(0) on startup to enabled assembly-optimised SHA-256
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.

Rusty Russell 22b8a88b48 common/daemon: in DEVELOPER mode, check for tal_parent() loops.
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.

Rusty Russell 76f116daf1 lightningd: minor cleanups
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.

Rusty Russell 1a4a59d221 common/daemon: common routines for all daemons.
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.
