Introduce local TDB storage for saving and restoring ratelimiter state (iops_tokens, bytes_tokens, last timestamp). Each share now persists its read/write limiter state under aio_ratelimit.tdb. Added VERSION pseudo-key for schema versioning On disconnect, save the latest state and close TDB.

2025-11-11lib:replace: Implement memset_explicit()Andreas Schneider1-0/+5
The memset_s() implementation is a bit obscure, as it requires a constraint handler to be set up. You don't really find any implmentations out there. With C23 memset_explicit() was added and this has been implemented for glibc 2.43 and also in FreeBSD.

2025-01-02remove usage of bzeroMichael Tokarev1-4/+0
bzero() function has been deprecated for a long time. In samba it is replaced with memset(). But samba also provides common memory-zeroing macros, like ZERO_STRUCT(). In all places where bzero() is used, it actually meant to zero a structure or an array. So replace these bzero() calls with ZERO_STRUCT() or ZERO_ARRAY() as appropriate, and remove bzero() replacement and testing entirely. While at it, also stop checking for presence of memset() - this function is standard for a very long time, and the only conditional where HAVE_MEMSET were used, was to provide replacement for bzero() - in all other places memset() is used unconditionally.

There is closefrom in some BSDs, but Linux ships this only as part of libbsd. Add a new implementation of it in libreplace. The one in libbsd of jessie and upstream differ and it has for example optimizations for FreeBSD, but it gets some of the array calculations slightly wrong from my point of view. If you want those, use libbsd. This replacement is optimized on Linux only looking at /proc/self/fd/, everything else would do the OPEN_MAX brute force fallback.
