From 01c934c81e55b79601122d8e0740c7946077c37e Mon Sep 17 00:00:00 2001

Subject: lib/util: Add back control of mmap and hash size in tdb for top level
 build

This passes down a struct loadparm_context to allow these
parameters to be checked.  This may be s3 or s4 context, allowing the
#if _SAMBA_BUILD_ macro to go away safely.
