2086699b70 common: add randbytes() wrapper to override cryptographic entropy: $CLN_DEV_ENTROPY_SEED
Only in developer mode, ofc.

Notes:
1. We have to move the initialization before the lightningd main trace_start,
   since that uses pseudorand().
2. To make the results stable, we need to use per-caller values to randbytes().
   Otherwise external timing changes the call order.

9977b72e8e common: add unified HSM secret handling module
This is a newer API to replace hsm_encryption.c and hsm_encryption.c, this tidies up the API to be used and also cleans things up to support our new formats. Our hsm_secret formats now include:
- Legacy 32-byte plain format
- Legacy 73-byte encrypted format
- New mnemonic format without passphrase (32 zero bytes + mnemonic)
- New mnemonic format with passphrase (32-byte hash + mnemonic)

This commit includes support to detect the format based on the file size and content structure. The hsm will store mnemonics in the hsm_secret file as:

`passphraseHash`mnemonic`

68f6a1a1dc common/jsonrpc_io: helper routines for reading JSON from sockets.
The efficient way to do this is to use membuf, which handles the buffer
control (only using memmove when necessary).  We have multiple places
where we opencoded this, some of which did not use membuf at all.

So now we create common infrastructure.  I tried making it a single
function but the various users are quite different, so instead I opted
for a toolbox approach.

65d997842e Makefiles: remove redundant dependencies, and have objects depend on their Makefile.
1. $(JSMN_OBJS) is not set anywhere.
2. You don't need to depend on CCAN_HEADERS, COMMON_HEADERS or JSMN_HEADERS: the top level Makefile has all object depedning on it.
3. Similarly, CCAN_OBJS.
4. Every object file should be rebuilt if its Makefile changes.

e120f87083 Makefile: create a library containing common, wire and bitcoin objects.
This means we don't have to manually choose what to link against,
which is much of the complexity of our Makefiles: the compiler will
automatically use any object files it needs to link.

We already do this for ccan as libccan.a, now we have libcommon.a.

We don't link against it for *everything*, as some tests require their own
versions.

Notes:
1. I get rid of the weird plugins/test/Makefile2 (accidental commit?)
2. Many tests change due to update-mocks.
3. In some places I added the missing dependency on the Makefile itself, though most are in the next
   patch.

ee47b9370f common/bolt12_id: new common routine for creating path secrets.
invoice_path_id is actually a generic path_id thing, so rename it.

We're going to use the same scheme for path secrets and the tweak to
node_id when we create a fake pubkey for invoice_requests, so a new
header is appropriate.

94a539ee3d Makefile: add CLN_NEXT_VERSION, functions encoding deprecation schedule.
Each feature has a name, and says when deprecation begins and ends.

There's an API coming to allow you to re-enable on a per-feature basis
even if it's ended (as long as it's not been removed from the code ofc!).

Default end is 6 months after deprecation, i.e. we complain about it
at that point, if we can detect its use.

e.g, a standard deprecation in v24.05:

v24.02: allowed
v24.02 with mods: allowed

master after v24.02: allowed unless deprecated APIs disabled.
v24.05: allowed unless deprecated APIs disabled.
v24.08: allowed unless deprecated APIs disabled.

v24.11: allowed unless deprecated APIs disabled, but logs at BROKEN level.

v25.02: allowed only if --i-promise-to-fix-broken-api-user=FEATURE.
v25.05: code is actually removed.

595fbd2a19 createinvoice: make a minimal blinded "path" in bolt12 invoice if none presented.
The "path" is just a message to ourselves.  This meets the minimal
requirement for bolt12 invoices: that there be a blinded path (at
least so we can use the path_id inside in place of "payment_secret").

We expose the method to make this path_id to a common routine: offers
will need this for generating more sophisticated paths.
