[PATCHES] Rationalizing and unifing Schannel

[simo]

I have been working on a patchset to enhance the schannel interface and
also to make it possible to share this code between S3 and S4 again.

The first 6 patches shouldn't be controversial.
The last 2 patches remove the use of ldb and goes back to use a tdb for
samba4, the comment on patch 7 explains the rationale.

Unless there are objections I will push this patches during the week.

Simo.
