CORBA26 — Indirections with chunking & fragmentation

When chunking and fragmenting, it is possible for a chunk length to be
inserted between the indirection tag and indirection offset.
Implementations must be careful to compute the indirection offset
correctly both when writing and reading to avoid errors.

For interoperability, we should elminate this possibility. From an
implementation point of view, the code for handling this special case
should already be there. Please see the original message (see
attachment) for a detailed description of the problem scenario and two
implementation possibilities.

Proposed resolution:

Elminate the possibility of chunk lengths between indirection tag and
indirection offset by changing the following paragraph in CORBA formal
00-11-03 15.3.4.6.
