5b3573135b s3:rpc_client: only pass the pipe_name to rpc_transport_np_init_send()
There's no need to have the ndr_interface_table at that stage...

885850b6aa s3/rpc_client: Fix array offset check
Previous to this commit we were modifying the offset before
the array offset check. This was causing a spurious debug
message indicating the offset was out of bounds. An second
problem is that upon detecting the error we don't exit the loop.
A third problem was that when reading the offset the check
didn't cater for the size of the integer address about to be read.

This commit moves the offset check to before the first read,
additionally when an error is detected now we actually exit the loop
and the offset have been corrected to include the size of the
integer to be read

f487211706 s3/rpc_client: Ensure max possible row buffer size is not exceeded
The max buf size of rows buffer should not exceed 0x00004000.
Ensuring this value is within limits means we can safely use
uint32_t offsets.

9b2f2302ee s3/rpc_client: cleanup unmarshalling of variant types from row columns
Prior to this change fn 'extract_variant_addresses' actually returns offsets
to the variant stored not the addresses, additionally the param in the
signature of the method is named offset where the param in reality is a
base address.
This change makes fn 'extract_variant_addresses' actually return addresses
instead of offsets and also changes the name of the incoming param. The
resulting changes are propaged to callers which hopefully makes what the
code is actually doing a little clearer

a61eb70328 s3/rpc_client: change type of offset to uint64_t
Offset can be a 32 or 64 bit address depending on the indexing addressing
mode negotiated by the client
With a 32 bit param we can only specify a 32 bit base address. This change
alone doesn't affect anything as it is the client itself that choses and
passes the base address offset and wspsearch is the only current user of
this code.
In this case even with 64bit addressing negotiated the address passed
represents only the lower 32-bits part of the address.
However, for coverage purposes it would be better for the client to use an
address that covers the full 64bit range of the address (when 64 bit
addressing is negotiated).
This change will alow the wspsearch client in a future commit to pass a
base address value with both the hi and low 32 bits values set to make up
the full 64 bit address.
