This matches db_tdb_do_locked() and the fetch_locked based fallback in
dbwrap_do_locked().
Calling dbwrap_record_get_value() is not allowed from within
dbwrap_do_locked()!
Now that rec.value is only internal, use it to remember the initial
payload value. This will simplify further code changes as it
makes the fetch_locked case.

Previously, if this function was called without an existing stackframe
then uses of talloc_tos in source3/registry trigger a panic. Since we
intend to add patches that allow access to this call with Python
bindings, that will not typically have a talloc_stackframe already, we
add a talloc_stackframe call around the call to
smbconf_init_reg_internal. This hides the use of talloc_tos in the
registry code from higher level code that needs to call smbconf.

This bases File-Ids on the inode numbers again. The whole stuff was
added because at that time Apple clients
1. would be upset by inode number reusage and
2. had a client side bug in their fallback implemetentation that
assigns File-Ids on the client side in case the server provides
File-Ids of 0.
After discussion with folks at Apple it should be safe these days to
rely on the Mac to generate its own File-Ids and let Samba return 0
File-Ids.

This first gets the clock_gettime_mono() value, converts to an NTTIME (as
this is what is stored in the dos attribute EA), then mixes in 8 bits of
randomness shifted up by 55 bits to cope with poor resolution clocks to
avoid duplicate inodes.
Using 8 bits of randomness on top of an NTTIME gives us around 114
years headroom. We can now guarentee returning a itime-based
fileid in a normal share (storing dos attributes in an EA).
