So after free, a chunk always contains junk bytes. This means that if we start with the right contents for a new page of chunks, we can *validate* instead of *write* junk bytes when (re)-using a chunk. With this, we can detect write-after-free when a chunk is recycled, not justy when a chunk is in the delayed free list. We do a little bit more work on initial allocation of a page of chunks and when re-using (as we validate now even on junk level 1). Also: some extra consistency checks for recallocaray(3) and fixes in error messages to make them more consistent, with man page bits. Plus regress additions. Remove malloc interposition, a workaround that was once needed for emacs 2023-05-27T04:33:00+00:00 otto 2023-05-27T04:33:00+00:00 urn:sha1:79242671d4fc62c0520403a6875e4c4254611365 ok guenther@ Add PROTO_NORMAL() declarations for the remaining syscalls, to avoid 2023-05-18T16:11:10+00:00 guenther 2023-05-18T16:11:10+00:00 urn:sha1:432d44bf3970806c89d3c69805013dc2cdc4cfc0 future, inadvertant PLT entries.
