In #1018 we got no information, except "Internal error". At least
if we tell the other side what went wrong, we're more likely to get
an answer.

If the source channel is onchain, we try to send a message to onchaind
which (1) doesn't care, (2) doesn't take a channel_fail_htlc msg, and
(3) causes us to crash in subd.c:
assert(!strstarts(sd->msgname(fromwire_peektype(msg_out)), "INVALID"));
Fixes: #821

We always hand in "NULL" (which means use tal_len on the msg), except
for two places which do that manually for no good reason.

We also fold opening_got_hsm_funding_sig() into the caller; it was
previously a callback before we decided to always use the HSM
synchronously.

When we clear and recreate ltmp, we attach it to whatever logbook it's on.
This, of course, is fraught, since it may be freed.
We could make it NULL-parented, but that makes YA special-case to free
when we exit (we try to keep valgrind happy by freeing everything). So
since the first log_book is the permanent one attached to lightningd,
just keep that parent when we re-build it after use.

As of version 5.0 Android requires all dynamically linked executables to support PIE. This allows programs to be loaded at a different addresses, making it harder for attackers to target.
Enable with PIE=1
When cross compiling it's important that the resulting config.h reflects the platform we are building for and not the one we are building on.
Otherwise we end up with a config.h that defines headers that are not there on the target platform, wrong endnianness and so on.
The -static flag is there to be able to easily run the configurator test executables on the build machine with qemu-*.
E.g. Without the -static flag the resulting dynamically linked ARM executables complain about the lack of linker (/lib/ld-linux-armhf.so or /system/bin/linker for Android), since these files are not usually available on the build machine building statically avoids this problem and results in a proper config.h for cross compiling.
