Move the uid/gid/acls/xattrs *_ndx assignments past check_batch_flags():
a mismatched-flag batch otherwise wrote F_XATTR(file) at offset 0 of
every file_struct, clobbering file->dirname. parse_negotiate_str() no
longer short-circuits on am_server, so each side picks its own #1 mutual
digest/checksum/compress choice rather than deferring to the peer's
order; man pages updated to match.

Glibc 2.43 added C23 const-preserving overloads to various string functions,
which change the return type depending on the constness of the argument(s).
Currently this leads to warnings from calls to strtok() or strchr().
Fix this by properly declaring the respective variable types.

- Size flist checksum data to hold the active size, not the max.
- Add a negotiated hash method to the daemon auth code.
- Use EVP for all openssl digests. This makes it easy to add more
openssl digest methods and avoids deprecation warnings.
- Support a way to re-enable deprecated digests via openssl conf
file and allow a default file to be configured.
- Supply a simple openssl-rsync.cnf file to enable legacy digests.
Change the logic in compat.c to construct the client_info string value
for a local copy so that the various checks of the string don't need to
make an exception for local_server.
- All the memory-allocation macros now auto-check for failure and exit
with a failure message that incudes the caller's file and lineno
info. This includes strdup().
- Added the `--max-alloc=SIZE` option to be able to override the memory
allocator's sanity-check limit. It defaults to 1G (as before).
Fixes bugzilla bug 12769.
The client does not pass "none" as a negotiation choice unless it's from
the user's environment list. The server still passes the "none" value
to the client unless its environment var excludes it.
- The env on the server side now affects the negotiated strings
that are sent to the client.
- A too-old remote rsync gets a default negotiated string value
so that an env restriction now handles old clients the same way
as new ones.
- Add the zlibx (external-code compatible) compression name.
- Re-enable zlib support with the external library so it can be
tried as a fallback if zlibx isn't available.
- Add --compress-choice=STR (aka -zz=STR) option.
- Make --cc=STR an alias for --checksum-choice=STR.
- Hook up the new compression negotiation logic.
- Add checksum negotiation to the protocol so that we can easily add new
checksum algorithms and each will be used when both sides support it.
- Increase the size of the compat_flags value in the protocol from a
byte to an int.
If both sides support the "V" compatibility flag, we send the file-list
flags as a varint instead of a 1-or-2 byte value. This upgrades the
number of reserved flag bits from 1 to 17 with very few extra bytes in
typical file-list data.
