We now make a copy of the given string, so that we can mark chunks
inline. Then we call dcerpc_binding_set_string_option() in order
to set the elements.

dcerpc_floor_set_rhs_data() handles the special cases now
and we keep the 'host' part unmodified except
EPM_PROTOCOL_IP addresses. No special '\\' handling anymore.

For EPM_PROTOCOL_IP we can only marshal ipv4 addresses,
everything else gets '0.0.0.0' (4 zero bytes on the wire).

They can be used to parse a fragmented NDR byte stream.
ndr_pull_append() appends more data that can be processed
and ndr_pull_pop() removed already processed data.
This will be used to implement dcerpc pipes, where we can get
a verify large amount of pipe chunks, once we processed a chunk
we can forget about the related data, but we may need to keep some
bytes in order to get the alignment right.

If we pull a pipe chunk we need a way to check if we
have enough bytes to parse the complete chunk.
Setting ndr_pull->flags |= LIBNDR_FLAG_INCOMPLETE_BUFFER
would change NDR_ERR_BUFSIZE (and later maybe others)
into NDR_ERR_INCOMPLETE_BUFFER.

This IDL code:
typedef [nodiscriminant] union {
[default] dcerpc_empty empty;
[case(LIBNDR_FLAG_OBJECT_PRESENT)] GUID object;
} dcerpc_object;
Compiles into the following default-before-case marshalling code:
switch (level) {
default: {
NDR_CHECK(ndr_push_dcerpc_empty(ndr, NDR_SCALARS, &r->empty));
break; }
case LIBNDR_FLAG_OBJECT_PRESENT: {
NDR_CHECK(ndr_push_GUID(ndr, NDR_SCALARS, &r->object));
break; }
}
The default entry before case does not change the flow of execution but
is more logical when present at the end of the switch statement.

This extracts the dcerpc_sec_verification_trailer from the end
of an ndr_pull structure, it found it reduces ndr->data_size.
NDR_ERR_ALLOC is the only possible error, all other errors
are ignored and a trailer with command count = 0 is returned.
