For private libraries we don't want versioned sonames,

This will be used to define plugins we provide to be used
via dbopen/dlsym to external consumers.
SAMBA_PLUGIN() is used instead of SAMBA_LIBRARY() in order
to make it more strict that these plugins can't be used as
normal depedency by other subsystems and libraries.
With require_builtin_deps=True we make sure that only
symbols explicitly marked with _PUBLIC_ are exported
and we only link to system libraries and include all
internal depedencies as builtin subsystems.

The 'provide_builtin_linking=True' option that allows wscript files
to specify that a SAMBA_{SUBSYSTEM,LIBRARY} will also create a
builtin version of them in addition.
The logic behind this is very similar to what we already have with the
'--builtin-libraries=BUILTIN_LIBRARIES' configure option.
This avoids the need for manual definitions of SAMBA_SUBSYSTEMS() with
like this:
bld.SAMBA_SUBSYSTEM('replace-hidden',
source=REPLACE_SOURCE,
group='base_libraries',
hide_symbols=True,
deps='dl attr' + extra_libs)
The builtin version will also make sure that it will include all
dependecies (of internal code) also in the builtin variant.
Note that this is also possible if the dependency also
provided 'provide_builtin_linking=True' in order to limit
the scope.
We now imply '-D_PUBLIC_=_PRIVATE_' and 'hide_symbols=True' for
builtin libraries and subsystems in order to avoid exporting
the symbols of them.
With 'require_builtin_deps=True' a library can specify that it
is only able to use libraries/subsystems marked with
provide_builtin_linking=True. As a result it won't
link against any other SAMBA_LIBRARY() dependency,
but link in everything internal. Only system libraries
still get linked dynamically.
Use 'git show -w' to see a reduced diff.

If we build a private library all symbols should be made private based
on a unique suffix.
When we use a unique soname and a unique symbol version suffix it's very unlikely
to hit conflicts due to inherited libraries.
For the abi checking we still use the original vnum as abi_vnum.

Playing tricks with redefining libraries, which may also be installed in
the system with the same version, isn't really a good thing.
It may work in some cases, but there are so many things which may go
wrong. So if we build a library as private/bundled library we should
change the soname of the library.
