Changelog-Removed: `hsmtool`: hsm_secret (ignored) on cmdline for dumponchaindescriptors (deprecated in v0.9.3)

This gives a nice way to ensure your secret is the correct one.
Also, we don't need to suppress VALGRIND for this test, now the output
races are fixed.
Changelog-Added: `hsmtool`: new command `checkhsm` to check BIP39 passphrase against hsm_secret.

Most unexpected ones are still 1, but there are a few recognizable error codes
worth documenting.
Rename the HSM ones to put ERRCODE_ at the front, since we have non-HSM ones
too now.

Also has to fix up tests.
Changelog-Fixed: cli doesn't required anymore to confirm the password if the `hsm_secret` is already encrypted.

Changelog-Changed: Support hsm specific error error code in lightning-cli
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

I did this by copying the updated bech32 code, and then re-patching in
our minor changes:
1. Headers modded (we need size_t)
2. Explicit length for bech32_encode/decode (not 90).
3. Exposing and bech32_ prefix for convert_bits, charset, charset_rev.

This makes use of the constant defined in the previous commits to more
accurately detect plaintext, encrypted, and invalid seeds. We now error
on invalid seeds.
Changelog-changed: hsmd: we now error at startup on invalid hsm_secret

This avoids duplication of both logic and error-prone values, such as
the salt. Grouping all hsm encryption logic into a public API will also
allow us to fuzz it.

This slightly breaks the API, but still accept the input: we just don't
take it into account anymore.
For `dumponchaindescriptors`, we have to still take the old place of the
`network` parameter into account to not entirely break the API.
Changelog-Added: hsmtool: password must now be entered on stdin. Password passed on the command line are discarded.

Actually, it's more complex to translate the xpub descriptor to
testnet because of the descriptor checksum.

This adds a command which outputs the two output descriptors
corresponding to our onchain wallet.
This can be useful for an external service to monitor / send fund to our
wallet.
Further, an "xpriv" version of such descriptors could be used to import
onchain funds on a new wallet.
Changelog-Added: lightning-hsmtool: a new command was added to hsmtool for dumping descriptors of the onchain wallet

tools: Add `generatehsm` method to hsmtool to derivate BIP32 seeds from a
mnemonic using the BIP39 standard.
The new method uses libwally for the BIP39 to BIP32 derivation. It also
fails if an hsm_secret file already exists, so we do not overwrite
someone else's wallet without noticing.
It allows the use of passphrases, the ECHO mode in the terminal is
disable for higher security.
It currently supports "en", "es", "fr", "it", "jp", "zhs", "zht".
Changelog-Added: hsmtool: `hsm_secret` generation from a seed-phrase following BIP39.
Note that check-whitespace and check-bolt already do this, so we
can eliminate redundant lines in common/Makefile and bitcoin/Makefile.
We also include the plugin headers in ALL_C_HEADERS so they get
checked.

Changelog-Fixed: Actually make the password argument optional for `guesstoremote` and `dumpcommitments` sub-commands, as shown in our documentation and help text.
Reported by `Barno` on #c-lightning IRC.
Changelog-Added: We now install `lightning-hsmtool` for your `hsm_secret` needs.
See: https://github.com/ElementsProject/lightning/issues/3717#issuecomment-644844594
It seems reasonable to add this to the standard install, and to document it properly as well, hopefully we can fill in the documentation better later on.
TIL: `rename` doesn't like its source and target to be on different
partitions. This was causing the `hsmtool` tests to fail whenever we ran them
on a different partition than the lightning-dir (e.g., `/dev/shm` for faster
testing), because we made the backup copy in the current working directory.
This changes this and creates the backup next to the original file, which has
a reasonable chance to be on the same partition.
Changelog-Changed: hsmtool: The `hsmtool` now creates its backup copy in the same directory as the original `hsm_secret` file.
This, in the case of data loss on a channel with `option_static_remotekey`
negotiated, allows to likely (if the dbid is not unreasonable) recover
the funds from a remote unilateral close just with the hsm_secret.
Changelog-added: A new command, 'guesstoremote', is added to the hsmtool. It is meant to be used to recover funds after an unilateral close of a channel with `option_static_remotekey` enabled.
This takes a dbid, a "depth" (how many points to dump), the hsm_secret
path, and a potential password to dump informations about all
commitments until the depth.
