ldb ABI versions in 4.17: should it include 2.5.1 & 2.5.2 versions too?

[Michael Tokarev]

I'm not sure if this matter or not (since ldb is tied with samba), but ldb in 4.17.0rc5
lacks versions 2.5.1 and 2.5.2 released within samba 4.16.x series, while previous minor
ldb releases are listed there.

Thanks,
