Case-insensitive handling of hostnames in lib/hash.c was removed in this commit 02524bf
This leads to "HOSTNAME" and "hostname" being two separate keys in the hashtable.
Hostnames are converted to lowercase when the path to the rrd file is constructed in write_data_to_rrd (gmetad/process_xml.c) so the aggregated data will likely end up in the same .rrd file anyway. However, it's more efficient to handle the hostnames in a case-insensitive manner first.
