early return was checking only if addrs was empty, ignoring addr.

Effect: when sending to a single recipient fails, that recipient is
not saved to the requeue file and is lost entirely. The return value
of 0 (false) propagates back as "success", causing the caller to

Fix by only returning early when there is nothing to save (both addrs
empty AND addr NULL). This ensures failed recipients are properly

Rename __unused macro to MLMMJ_UNUSED

Identifiers with double-underscore prefixes are reserved for the C
implementation. Older glibc headers (bits/stat.h) use __unused as a
struct field name, so the mlmmj macro expansion produces invalid syntax

mlmmj-process: fix NULL deref in owner mail reprocessing path

When mail is addressed to listname+owner, mlmmj-process calls
do_all_the_voodoo_here() a second time to strip envelope headers
before forwarding to the list owner. This second call reuses the
same allheaders list that was already populated by the first call.

Inside do_all_the_voodoo_here(), scan_headers() appends the new
mail's headers to the passed-in allhdrs list, while allunfoldeds
is a fresh local list containing only the headers from the current
scan. The main loop then iterates all entries in allhdrs (which now
includes headers from both calls) while popping from allunfoldeds
(which only has entries from the second scan). Once the unfolded
entries are exhausted, tll_pop_front() on the empty list dereferences
NULL and crashes.

Fix this by passing a separate local strlist to the second call so
that allhdrs and allunfoldeds stay in sync.
