s3: libsmbclient: Fix cli_splice() fallback when reading less than a complete file.
We were always asking for SPLICE_BLOCK_SIZE even when the
remaining bytes we wanted were smaller than that. This works
when using cli_splice() on a complete file, as the cli_read()
terminated the read at the right place. We always have the
space to read SPLICE_BLOCK_SIZE bytes so this isn't an overflow.

The comment immediately above this code says "don't allow local

whether the request is local or remote.
This means that an intentional remote attach from a client will not
work correctly. No real client should ever do that since clients
attach so they an access databases locally. Perhaps some sanity
checks should be added.
Some compilers (e.g. xlc) ignores unsupported features, generates a
warning, but does not fail compilation.
This ensures that any compiler warnings are treated as errors and the
feature support is correctly identified. This adds equivalent compiler
option to -Werror for xlc.

Make the corresponding change to the semantics in the daemon by

There is a mismatch between the ideas of VNN map and active nodes. A
node that is not in the VNN map but is active can still host database

introduced and then the logic was not updated.
The only place where the VNN map is relevant is when finding the
