KCC: Copy KCC core out of samba_kcc into samba.kcc module
The "module" is not actually used at this point, which is just as well
as it would be utterly broken. This copy is just to show that the
eventual move is really a move and not a complete rewrite.
Note that if this file is not executable (and it really shouldn't be),
this commit causes the samba.tests.source test to fail with "Files
with shebang line that are not executable".
