205e198471 tdb2: careful on wrap.
It's much harder to wrap a 64-bit tdb2 than a 32-bit tdb1, but we should still
take care against bugs.

Also, we should *not* cast the length to a size_t when comparing it to
the stat result, in case size_t is 32 bit.

80c3ba8123 tdb2: add a capability list from the header.
This allows even more extensibility in future: in particular, the top
bits of each capability tell us what to do if we don't understand it:
fail the open, fail to open for write, or don't try to check the
format.

tdb_check needs to understand the capability list so it can know to
skip over it: each element in the list is prefixed with the type tag
and the length.

eff985b7ef tdb2: add an internal TDB_CANT_CHECK flag.
This will be used shortly to indicate that a TDB2 file indicates it
cannot be checked.

2d7c85a971 tdb2: fix prototypes which return enum TDB_ERROR.
Since enums and ints are compatible in C, the compiler didn't warn
that our prototypes for these functions disagreed with the
definitions.

2237daed7e tdb2: add error conversion functions.
This clarifies the code a little, but also provides a more explicit
mechanism which can be used to debug error handling (by introducing
tdb_err_t and making it a pointer type).

8e14a3e06d tdb2: unify tdb1_check and tdb1_summary into tdb_check and tdb_summary.
Switch on the TDB_VERSION1 flag.  Also, change tdb1_check's checkfn argument
to return an error code (and set tdb->last_error accordingly).

c16184f83b tdb2: merge tdb1_context into tdb_context.
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.
