[SSSD] [PATCH] Remove replace

[Sumit Bose]

Hi,

this patch removes the replace subdirectory. The code isn't used so far
on the supported Linux platforms and is outdated compared to the
upstream code in the samba tree. If we will need some replacements when
porting to other platforms we might reintroduce the code, use gnulib or
use some other strategy.

bye,
Sumit
