TDB allows this for internal databases, but it's a bad idea, since the
name is useful for logging.
They're a hassle to deal with, and we'd just end up putting "unnamed"
in there, so let the user deal with it. If they don't, they get an
informative core dump.

The performance numbers for transaction pagesize are indeterminate:
larger pagesizes means a smaller transaction array, and a better
chance of having a contiguous record (more efficient for
ntdb_parse_record and some internal operations inside a transaction).
On the other hand, large pagesize means more I/O even if we change a
few bytes.
But it also controls the multiple by which we will enlarge the file,
and hence the minimum db size. It's 4k for tdb1, but 16k seems
reasonable in these modern times.

Now our database is always a multiple of NTDB_PGSIZE, we can remove the
special handling for the last block.

As copied from tdb1, there is logic in the transaction code to handle
a non-PGSIZE multiple db, but in fact this only happens for a
completely unused database: as soon as we add anything to it, it is
expanded to a NTDB_PGSIZE multiple.
If we create the database with a free record which pads it out to
NTDB_PGSIZE, we can remove this last-page-is-different logic.
Of course, the fake ntdbs we create in our tests now also need to be
multiples of NTDB_PGSIZE, so we change some numbers there too.

ntdb uses tdb's transaction code, and it has an undocumented but implicit
assumption: that the transaction recovery area is always aligned to the
transaction pagesize. This means that no block will overlap the recovery
area.
This is maintained by rounding the size of the database up, so do the same
for ntdb.

We were missing the last few bytes. Found by 100 runs of ntdbtorture
-t -k.
The transaction test code didn't catch this, because usually those
last few bytes are irrelevant to the actual contents of the database.
We fix the test.

Our external test helper is a bit primitive when it comes to doing STORE or
FETCH commands: let us specify the data we expect, instead of assuming it's
the same as the key.

This is a fairly common pattern in Samba, and if we log an error on
every open it spams the logs. On the other hand, other errors are
potentially more serious, so we still use NTDB_LOG_ERROR on them.

We document that the child of a fork() can do a brunlock() if the parent
does a brlock: we should not log an error when they do this.
Also, test the case where we fork() and return inside a parse function
(which is allowed).

In tdb, we grab the open lock immediately after we open the file. In
ntdb, we usually did some work first. tdbtorture managed to get in
before the creator grabbed the lock:
testing with 3 processes, 5000 loops, seed=1338246020
ntdb:torture.ntdb:IO Error:ntdb_open: torture.ntdb is not a ntdb file
29023:torture.ntdb:db open failed
At cost of a little duplicated code, we can reduce the race.

It was a hack to make compatibility easier. Since we're not doing that,
it can go away: all callers must use the return value now.

This renames everything from tdb2 to ntdb: importantly, we no longer
use the tdb_ namespace, so you can link against both ntdb and tdb if
you want to.
This also enables building of standalone ntdb by the autobuild script.

Judging by code it's tdb1, where you needed to free old key's dptr
manually.

This commit changes the default file server to be s3fs. Existing
installs wishing to keep the ntvfs file server need to set this in
their smb.conf:
server services = +smb -s3fs
dcerpc endpoint services = +winreg +srvsvc

This simplifies our supported configurations down to those that we test and expect
to work. security=domain and domain logons = yes has never made much sense, and
security=ads and domain logons = yes was only ever used in early experiments for
our AD support using smbd.
The correct way to be an AD DC is to set "server role = active directory domain controller"
Andrew Bartlett
This will allow us to detect from the smb.conf if this is a Samba4 AD
DC which will allow smarter handling of (for example) accidentially
starting smbd rather than samba.
To cope with upgrades from existing Samba4 installs, 'domain
controller' is a synonym of 'active directory domain controller' and
new parameters 'classic primary domain controller' and 'classic backup
domain controller' are added.

The IRIX compiler doesn't support '...' in a macro.
