Fixed issue 2245 - Creating more than 41 vlabels causes drop_grapth to fail
with "label (relation) cache corrupted" and crashing out on the following
command.
This was due to corruption of the label_relation_cache during the HASH_DELETE
process.
As the issue was with a cache flush routine, it was necessary to fix them
all. Here is the list of the flush functions that were fixed -
static void flush_graph_name_cache(void)
static void flush_graph_namespace_cache(void)
static void flush_label_name_graph_cache(void)
static void flush_label_graph_oid_cache(void)
static void flush_label_relation_cache(void)
static void flush_label_seq_name_graph_cache(void)
Added regression tests.
