[389-devel] Please review 48844: Regression introduced in matching rules by DS 48746

[thierry bordaz]

Hello,

The patch for the ticket https://fedorahosted.org/389/ticket/48746 
<https://fedorahosted.org/389/ticket/48745>;, introduced a regression.
This patch contained two parts:

 1. Hardening of MR code to prevent a crash when index_create function
    do not set SLAPI_PLUGIN_OBJECT
 2. rewriting of the code looking for MR plugin that can handle a given OID

The Part 2 of the code was wrong because it did not take into 
consideration old and new MR plugin style that register their indexer 
create function in a different way.
The Patch for 48844 basically revert the second part of the patch 48746.

thanks
thierry
