lib/tdb_compat: header for tdb1 vs tdb2. TDB2's API is slightly different from TDB1. In particular, all functions return 0 (TDB_SUCCESS) or a negative error number, rather than -1 or tdb_null and storing the error in tdb_error() (though TDB2 does that as well). The simplest fix is to replace all the different functions with a wrapper, and that is done here. Compatibility functions: tdb_null: not used as an error return, so not defined by tdb2. tdb_fetch_compat: TDB1-style data-returning tdb_fetch. tdb_firstkey_compat: TDB1-style data-returning tdb_firstkey tdb_nextkey_compat: TDB1-style data-returning tdb_nextkey, with TDB2-style free of old key. tdb_errorstr_compat: TDB1-style tdb_errorstr() which takes TDB instead of ecode. TDB_CONTEXT: TDB1-style typedef for struct tdb_context. tdb_open_compat: Simplified open routine which takes log function, sets TDB_ALLOW_NESTING as Samba expects, and adds TDB_CLEAR_IF_FIRST support. Things defined away in TDB2 wrappers: tdb_traverse_read: TDB2's tdb_traverse only uses read-locks anyway. tdb_reopen/tdb_reopen_all: TDB2 detects this error itself. TDB_INCOMPATIBLE_HASH: TDB2 uses the Jenkins hash already. TDB_VOLATILE: TDB2 shouldn't have freelist scaling issues. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

tdb2: tie it into build process if --enable-tdb2-breaks-compat This is simplistic. We need to support making TDB2 a standalone library, but for now, we simply built it in-tree. Once we have tdb1 compatibility in tdb2, we can rename this option to --enable-tdb2. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
