This is a direct port of the previous patch, to the TDB2 codebase.

This caused a crash on PPC64 when we failed the mmap (found by failtest,
reported by Amitay)

The TDB2 tests are stricter about this; they want every error logged.

It's actually quite a good fit; we use compare_wrong_bucket for dead
records, which is kind of correct (they should be in the free list).

Switch on the TDB_VERSION1 flag.

Finally, we gut tdb1_open() to the tdb1-specific parts, and call it
from tdb_open if they specify the TDB_VERSION1 flag or the version is
a TDB1.
We also unify tdb_close(), based on the TDB_VERSION1 flag.
Note that tdb_open(TDB_VERSION1) will fail on an existing tdb if it's
a TDB2.

Finally, we split out the tdb2-specific parts of tdb_context, and put
them into a "tdb2" sub-struct; the tdb1 parts go into a "tdb1"
sub-struct. We get rido of tdb1_context and use tdb_context
everywhere.

There's also a semantic change here: for tdb1, being read-only meant no
locking, and it was an error to try to lock a r/o database. For TDB2, you'd
need to specify TDB_NOLOCK, which suppresses locking silently.

Because tdb2 allows multiple opens of the same TDB, we separate out
the file information from the struct tdb_context. Do the same for
tdb1.

This means getting rid of TDB_VOLATILE (perhaps we should use an
attribute for that?), TDB_INCOMPATIBLE_HASH (use the
tdb_attribute_hash for that) and TDB_CLEAR_IF_FIRST (use the
tdb_attribute_openhook for that).
We also get rid of TDB_DISALLOW_NESTING: that's the default for TDB2.

To do this, we make sure that the first few fields of tdb1_context and
tdb_context are the same.
This sweep also fixes up a few paths where we weren't setting
tdb->ecode before our old logging function.

We import the entire codebase, putting a "tdb1_" prefix on the files
and changing the "tdb_" prefix to "tdb1_" everywhere.
The next patches will gradually merge it with the TDB2 code where
necessary.
