Using public headers to write ABI vscripts

I've been working on a patch to use the mksyms.awk approach to get a
list of public headers and symbols from our public headers files, and
use that instead of just the regular-expression abi_match.

https://git.samba.org/?p=abartlet/samba.git/.git;a=shortlog;h=refs/heads/abi-public-headers

It would be great to get this in to 4.0, but I'm having some waf
challenges I'll need to get past.  The challenge relates to the grouping
from the build ordering, because we need a vscript for libreplace (very
early) but vscripts can depend on pild-generated headers.  We may need
to rely on pure dependencies rather than also the groups.

This came up because I had to bump the ldb ABI (it needed a bump for the
behaviour change, but it spiked my interest) when adding a private,
internal symbol.

I'm also working in this area though my needs are bit different at the moment.

https://git.samba.org/?p=ab/samba.git/.git;a=shortlog;h=refs/heads/stableabi
has number of patches that attempt to introduce API namespaces.

I need stable mapping between API namespace and version node name
associated with it that spans across multiple releases (instead of
SAMBA_<VERSION> default symbol changing every release without actual
semantical and ABI change) for certain important private libraries.

One issue we have currently is that ABI generators expect to use
numbers as versions only. This is done with the idea that vnum

I'm a bit confused.  In what sense is a library that is being linked
