For compiling against a checkout of the stand-alone libmdb,
which has a branch 'mdb.master' with its own root:
    git clone --branch=mdb.master <openldap_repo_dir> mdb
    set_mdb="MDB_SUBDIR=`pwd`/mdb/libraries/libmdb"
    ... maybe modify mdb repository for testing ...
    cd <openldap_repo_dir>; make $set_mdb

  database entry in cn=monitor
- improve support for custom attribute/callback registration
  in back-monitor
- design API for registered antry/attr/callback removal in back-monitor

HEADS UP: now back-bdb requires back-monitor to be present, either static
or dynamically loaded __before__ back-bdb/back-hdb is initialized.
This works for sure if both back-bdb & back-monitor are static or dynamic
(provided back-monitor.la is loaded before back_bdb.la); it is not clear
what happens if back-bdb is static and back-monitor is dynamic.  In case,
either make back-bdb monitoring conditional, or hardwire back-monitor
much like back-config and back-ldif.

- BDB context csn codes moved to a separate function in back-bdb/ctxcsn.c

committin what I have so that someone else might be able to work it.
