Rusty Russell aa5c7e763f libplugin: make set callback for options take plugin ptr, check correct type.
I added a plugin arg and was surprised that compile didn't break.
This is because typesafe_cb et al are conditional casts: if the type
isn't as expected it has no effect, but we're passing plugin_option() through
varargs, so everything is accepted!

Add a noop inline to check type, and fix up the two cases where we
used `const char *` instead of `char *`.

Rusty Russell ecc030f12d lightningd, libplugins: allocate opt strings from tmpctx, not NULL.
Previously, if these failed we always exited; once we have dymamic
configs this would be a (tiny) memory leak, so use tmpctx.

Rusty Russell 4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
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.
