This takes care of alignment sizes, so that it works on both 32-bit and

In the control request, database id which is a 32-bit integer is sent
on wire as a 64-bit integer rather than a 32-bit integer. If we
convert the database id to 64-bit integer before sending, the order of
32-bits with database id will vary depending on the endian-ness.
Instead send the database id as first 32-bits and zeros as next 32-bits.

In the process, make arguments const so that ctdb_sock_addr_cmp() can

Even though database id is 32-bit, it's sent on wire as 64-bits.
The database id is the first 32-bits on the wire. This needs fixing
eventually, but for now keep the same wire format.

If the header is specified, then the datalen should be incremented.
There are two ways of marshalling ctdb_rec_data:
1. ctdb_rec_data->header is NULL and ctdb_rec_data->data embeds both
the header and the value. Used in recovery for push/pull of records.
2. ctdb_rec_data->header is not NULL and ctdb_rec_data->data embeds
only the value. Used everywhere else.
In both cases, the wire format includes the header and the value.
There is nothing in the wire format to inform the unmarshalling code
whether to extract the header separately or not.
In the current code the header is extracted depending on whether the
header argument to the extractor routine is NULL or not. This is insane
and highly error-prone.
So in the new API, unmarshalling code never extracts the header. If the
caller requires the header, then it can be extracted separately using
special function ctdb_ltdb_header_extract().
