Internal functions should not be part of symbols that are visible
outside the library. Using -fvisibility=hidden hides all internal
functions from the public ABI.

I'm happy with that changes. Petri?

small note that it will be much more easy to review if this patch will 
be slitted on 2 parts:
1. new functional (abi_begin.h, abi_end.h,  makefiles and configure.) 2. 
All other files instructed
with begin and end. So I had to apply patch to find proper things.

Thank you,
Maxim.

This adds a lot of machinery that needs to be included in every platform
API file.  The advantage of the abi_begin/end files is that they simply put
this in a common (platform-dependent) separate set of files which can be
maintained in one place rather than being distributed over many files that
all need to be kept in sync.

Note that ODP does not specify what needs to be in those files, so
additional #includes based on specific architecture can similarly be in one
place rather than many.  For now the #pragmas seem to be all that we need
but we can add to that if we determine that more is needed.

Do you have a definitive reason to not use the ABI begin approach, we have
differing ideas so we need to specify the facts supporting the proposals I
think.

Some things that strike me in this proposal of keeping it down in the
reference implementation.

   - It creates more work to maintain, more files
   - Other implementers must also take on the burden of maintaining it
   - It less clear what functions are part of the ABI since a developer now
   needs to look not in a specification but in the reference implementation to
   understand what is part of the ABI, that is much harder to follow.

This topic has had a good discussion in calls.

Petri has reservations that putting this in the spec file will prove to be
insufficient when we take on the bigger ABI issues beyond the packaging
problems we are solving here. But Petri agreed that the API white list for
what symbols appear in the library can be in the spec file for v1.9

Bill agreed to send an updated patch that does not use the term ABI in the
marking macro as this was contentious.
