libglusterfs/rbtree: change rbthash_init_table to take no of expected entries in the hash table as argument.
- the expected number of entries is used to create the memory pool of the hash table. Having constant macro for this purpose is not suitable since different users of rbtree based hash table store different number of entries in the table. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 335 (Io-cache optimization) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=335
